Question

write the number of p electrons in 1 . magnesium 2. phosphorus​

Answer 1

Answer:

2,8,2 and 2,,8,5

Explanation:

magnesium has atomic number 12 so electronic configuration is 2,8,2 it has 2 electron in K shell 8 electRon in L shell and 2 electron in M shell the valence shell so no of electron is 12 as p=e=z

Phosphorus atomic number 15 so electronic configuration is 2,8,5 it has 2 electron in K shell 8 electRon in L shell and 5 electron in M shell the valence shell so no of electron is 15 as p=e=z
