Question

why sodium atom has lower electron affinity than chlorine atom

Answer 1

do u know what is electron affinity?
@runel

Answer 2

yes

Answer 3

explain :)

Answer 4

tel me the answer first i need it fast

Answer 5

what is the nature of chlorine?

Answer 6

idk

Answer 7

its electronegative

Answer 8

and it needs 1 electron to fill its octet @runel

Answer 9

k

Answer 10

so its accepts the electron easily whereas Na is electropositive
it does not need

Answer 11

Don't 'k' rvc. r00d.

Answer 12

Electron affinity-energy associated with adding electrons usually to fill an orbital to achieve a stable or an 8 electronic configuration. Energy may be released or required to fill an atom. Energy release is favoured. for example, Chlorine and sodium, when chlorine gain an extra electron it releases energy -(value), the larger the value of negative the more favoured. Sodium gains that electron, sodium does not want that electron so energy is required to put that electron (+ve) value.
