What are the observed periodic trends in electron affinity check all that apply?
What are the observed periodic trends in electron affinity check all that apply?
Explanation: Electron affinity from close observations on the periodic table increases from left to right across a period and decreases downward a periodic group. Electron affinity is a measure of the readiness of an atom to gain electrons.
What is the periodic trend for electron affinity?
There are general trends in electron affinity across and down the periodic table of elements. Electron affinity generally increases across a period in the periodic table and sometimes decreases down a group.
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 appears to be the trend in the electron affinity as you move from top to bottom down a column?
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.
How do you know which element has the highest electron affinity?
Electron Affinity Trends Therefore, elements with the highest electron affinity in the top right corner of the periodic table.
Which element has highest electron gain enthalpy?
chlorine
Which has more electron gain enthalpy S or O?
Answer. Oxygen does not have a d-orbital, but sulphur has a d-orbital. Whereas sulphur has plenty of space in the d-orbital and has comparatively lesser electron repulsion. Hence, Sulphur has more electron gain enthalpy than Oxygen.
What is the highest electron configuration?
valence shell
Which order of ionization energy is correct?
-That is why the correct order of ionisation energy is C < O < N < F.
What is the electron affinity of mercury?
0 kJ mol‑1
What is the electron affinity of arsenic?
The electron affinity of arsenic is 78 kJ mol‑1.
What group has the highest electron affinity?
Nonmetals
Why does zinc have a positive electron affinity?
Electron affinity is different than electronegativity. Zinc having a higher electron affinity (more positive) indicates that when it gains an electron its energy lowers less than when copper gains an electron, which is consistent with the electronegativity statement.
Which of the following has the highest electron affinity?
O−
Why chlorine is more electron affinity than fluorine?
the electron affinity of the fluorine is less than chlorine because the size of fluorine is too small as size decreases from left to right inside period, whereas chlorine has a larger size to accommodate electrons hence electron affinity of chlorine is more than fluorine.
Why does fluorine have a high electron affinity?
2 Answers. Fluorine, though higher than chlorine in the periodic table, has a very small atomic size. This makes the fluoride anion so formed unstable (highly reactive) due to a very high charge/mass ratio. As a result, fluorine has an electron affinity less than that of chlorine.
