Question

we know that electron affinity is greater in periods but the largest electron affinity of cl is from group were as decreased a electron affinity so why not highest electron affinity from period while from group​

Answer 1

Explanation:

Electron affinity generally increases across a period in the periodic table and sometimes decreases down a group. ... 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.

Answer 2

Answer:

electron has a negative charge Photon has and positive charge and neutron has neutral an carbon atom atomic number is 6 number of electrons is 6 its electronic configuration is 2 4 number of protons in it is is 6 and there are three isotopes of carbon C11 C12 2c 13
