Question

do MG+ and NA ions have same number of electrons
​

Answer 1

Answer:

yes

Explanation:

as ec of both becomes 2,8

Answer 2

Answer:

Yes· Both  $Mg^+$ ion and the Na have the same number of electrons·

Explanation:

Sodium is an element that belongs to the first group and the third period in the periodic table· It has an atomic number of eleven and has eleven electrons around the nucleus in its neutral state· Its electronic configuration is $1s^2\ 2s{^2\ 2p^6\ 3s^1$·

Magnesium, Mg is an element that belongs to the second group and the third period in the periodic table· It has an atomic number of twelve and has twelve electrons around the nucleus in its neutral state· Its electronic configuration is $1s^2\ 2s^2\ 2p^6\ 3s^2$·

$Mg^+$ is the cation that formed by the loss of one electron from the valence shell of the magnesium· So its electrons become eleven and the electronic configuration becomes $1s^2\ 2s{^2\ 2p^6\ 3s^1$ which is similar to the electronic configuration of sodium element·

Hence, both $Mg^+$ ion and Na has the same electrons·
