What is the general trend regarding electron affinity?

The general trends of the electron affinity are that it increases from left to right across the periodic table due to an increase in the nuclear charge, and it increases from bottom to top due to the effect of atomic size.

What is the general trend for electron affinity values going across a period?

Electron affinity generally increases across a period in the periodic table and sometimes decreases down a group. These trends are not necessarily universal. The chemical rationale for changes in electron affinity across the periodic table is the increased effective nuclear charge across a period and up a group.

What is the trend down a group of electron affinity?

When moving down a group, the electron affinity generally decreases. This is because as you go down the period table, new valence shells are added increasing the atomic radius. The new orbital is further away from the nucleus, meaning the attraction between the positively charged nucleus and the new electron decrease.

What does electron affinity depend on?

factor which affect electron affinity are: atomic size and Nuclear charge. As atomic radii increases, electron affinity increase. As nuclear charge increase, electron affinity increase. it decrease down a group and increases across a period.

What are the trends and exceptions to the trends in electron affinity?

What are the trends and exceptions to the trends in electron affinity? The electron affinities of the elements in Group 17 are larger (more negative) than the elements in Group 1. Elements in Group 14 have larger (more negative) electron affinities than elements in Group 15.

What is the increasing order of electron affinity?

Hence, correct order of increasing electron affinity is: I.

Which of the following is the increasing order of electron affinity of halogen?

Electron affinity increases in a period and decreases in a group. But, fluorine atom, due to its small size cannot release high amount of energy. Hence, among halogens, chlorine atom has high value of electron affinity and the order is Cl>F>Br>I.

What is the order of increasing electron affinity?

Patterns in Electron Affinity. Electron affinity increases upward for the groups and from left to right across periods of a periodic table because the electrons added to energy levels become closer to the nucleus, thus a stronger attraction between the nucleus and its electrons.

What is the order of electron affinity?

Electron affinity is the tendency is attract shared pair of electron towards itself. Its value decreases in a group and increases in a period. The correct order of electron affinities is as follows N.

What is the trend in electronegativity from top to bottom?

From top to bottom down a group, electronegativity decreases. This is because atomic number increases down a group, and thus there is an increased distance between the valence electrons and nucleus, or a greater atomic radius.

What is the general trend of electronegativity as you go down the periodic table?

On the periodic table, electronegativity generally increases as you move from left to right across a period and decreases as you move down a group. As a result, the most electronegative elements are found on the top right of the periodic table, while the least electronegative elements are found on the bottom left.

Why electron affinity decreases down the group?

Electron affinity decreases down the groups and from right to left across the periods on the periodic table because the electrons are placed in a higher energy level far from the nucleus, thus a decrease from its pull.

Why does electron affinity increase from bottom to top?

Electron affinity increases from left to right within a period. This is caused by the decrease in atomic radius. Electron affinity decreases from top to bottom within a group. This is caused by the increase in atomic radius.

What is the order of decreasing electron affinity?

Which has highest electron affinity?

Chlorine
Chlorine has the highest electron affinity among the elements. Its high affinity can be attributed to its large atomic radius, or size.

Which of the following is a general trend for the electronegativity of elements in the periodic table?

On the periodic table, electronegativity generally increases as you move from left to right across a period and decreases as you move down a group.

Why do ionization energy and electron affinity have the same trend?

The general trend in the electron affinity for atoms is almost the same as the trend for ionization energy. This is because both electron affinity and ionization energy are highly related to atomic size. Large atoms have low ionization energy and low electron affinity. Therefore, they tend to lose electrons.
