Sons and daughters are integral parts of any family, and their roles and responsibilities within the family dynamic can vary greatly depending on cultural and societal norms. In many societies, there are specific expectations and stereotypes placed on sons and daughters, which can shape their experiences and opportunities in life. In this essay, we will explore the ways in which sons and daughters are treated differently in various societies, and how these differences can impact their lives and relationships with their parents and siblings.

One of the most significant ways in which sons and daughters are often treated differently is in terms of their roles and responsibilities within the family. In many traditional societies, sons are often expected to take on more responsibilities and have more authority within the family, while daughters are expected to focus on domestic tasks and be more submissive to their male relatives. This can create a power dynamic within the family that can be difficult for daughters to navigate, and can also limit their opportunities and potential in life.

Additionally, sons and daughters may be treated differently in terms of their education and career opportunities. In some societies, daughters may be discouraged from pursuing higher education or certain careers, while sons may be encouraged to pursue these paths. This can create a gender-based divide in terms of what is expected of each child, and can have long-term consequences for their future prospects and success.

However, it is important to note that these gender-based expectations and stereotypes are not universal, and there are many societies where sons and daughters are treated more equally. In these societies, both boys and girls are encouraged to pursue their interests and dreams, regardless of gender. This can create a more equal and fair environment for both sons and daughters, and can help to break down the traditional gender roles and stereotypes that can limit the potential of both genders.

In conclusion, sons and daughters are often treated differently in various societies, and these differences can have a significant impact on their lives and opportunities. It is important to recognize and challenge these gender-based expectations and stereotypes, and to create a more equal and fair environment for both sons and daughters to thrive and reach their full potential.

Ionization Energy Definition and Trend

why does ionization energy increase

As the force of attraction between the nucleus and electron increases, it becomes difficult to remove the outermost electron from an atom. Large increases in IE like this indicate changes in the main energy levels of the atom. The negative ions are more significant in the number of electrons than protons. Answer: The first ionization energy is the minimum energy required to remove the first electron from an isolated atom or molecule. Ionization energy deals with the removal of electrons from an atom. The electron removed is at the highest energy, furthest from the nucleus. Ionization Energy Trend Ionization energy is correlated with the number of protons in the nuclei of an atom, and its amount of electron shells.

Likewise, we can have negative ions. The first drop is due to a slight increase in distance from the nucleus as the outer electron occupies a new subshell slightly further away from the nucleus. The periodic table of elements is organized in a way that creates an ionization energy trend. Calculate the wavenumber for the shortest wavelength transition in the Balmer series of atomic hydrogen. For example, both lithium and fluorine have the same amount of electron shells but differ in their number of protons.

why does ionization energy increase

This is due to the shielding or screen effect of the outer electrons from the nucleus and so the attraction is weaker and they are more easily removed. Ionization Energy Definition and Trend. What determines ionization energy? By the method of show and tell normally used in flashcards, the students can retain a lot of information about ions and atomic structures as well as ionic properties and energy. It is expressed in joules or electron volts. Noble gases are considered as the most stable elements in the periodic table. According to the principle, electrons fill orbitals starting at the lowest available energy states before filling higher states e.

Does the ionization energy increase?

why does ionization energy increase

This is due to the fact that the magnitude of nuclear charge is same but number of electrons keep increasing in the shell. So our ionization energy increases steadily when electrons are being taken out of the same shell and our effective nuclear charge is rising. Hence greater will be the attractive force of nucleus towards electron. Similarly the second ionisation energy is used to remove second electron from the already electron deficit atom. The electrons are therefore held less tightly around the nucleus in atoms of elements going down a group. Why does ionization energy decrease from top to bottom on the periodic table? The name itself suggests that first ionisation energy is related to the first electron. Moving left to right across a period, atomic radius decreases, so electrons are more attracted to the nucleus.

Ionization Energy Questions

why does ionization energy increase

How do you know when ionization energy increases? The nuclear charge's pull on electrons has way more effect on the ionization energy than the gradual shielding does shielding will have a bigger impact down the periods because of different energy levels. The reason for the discrepancy is due to the electron configuration of these elements and Hund's rule. This would make it easier to remove that outer electron, and so I would say the opposite: the ionization energy should lower when we go to the right. Provide details and share your research! An increase in electron orbits results in a decrease in ionization energy because the distance between the nucleus and its outermost electrons increases, which decreases the influence the nucleus has on its outermost electrons. The arrangement of chemical elements in the periodic table is done in increasing values of atomic numbers. Because valence electrons are the furthest from the nucleus of the atom, they are influenced the least by the atom's positively charged nucleus the least. Hence, the ionisation energy decreases on moving down the group.

The atomic number increases by 1 as we move ahead in a period. Why does ionization energy increase from left to right? If em radiation of wavelength 242 nm is sufficient to ionize the sodium atom. It is important to know the meaning of ionisation energy first, so we shall discuss about ionisation energy and then continue with our discussion. How does ionization energy change down a group? From what I understand, in a stepwise ionization process, it is always the highest-energy electron the one bound least tightly that is removed first. Helmenstine, Anne Marie, Ph. The notes on ionisation energy provided by Vedantu are well researched and thoroughly evaluated by experts in their fields.

why does ionization energy increase

Charge of the protons is not perfectly shielded by the other electrons, so there's a slight imbalance that manifests as a slightly lower binding energy. The ionization energy of the elements within a group generally decreases from top to bottom. What is the second ionization energy? Therefore the closer the electron to the nuclear the higher the attraction force, and thus the higher the energy required to overcome this attraction and remove the electron. The outermost electrons are further from the positive-charged nucleus, so they are easier to remove. The noble gas has a filled valence shell, so it resists electron removal.

why does ionization energy increase

This happens due to the reason helium holds two electrons in 1s orbit, which means the electron is very close to the nucleus and also unscreened, thus required very high energy to release from the nucleus. There are trends in the periodic table for ionization energy when you go across a period row or down a group column. The higher the ionisation energy, the more difficult it becomes to remove an electron. Therefore, the lowest ionisation energy will be Francium, and the highest ionisation energy will be Helium. Ionization energy is how much energy is needed to remove an electron from the valence shell the outermost shell. More positively charged protons in the nucleus increases the influence on the negatively charged electrons and therefore pulls them more tightly around the nucleus.
