Answer 1

Question #48813, Chemistry, Inorganic Chemistry

The ground state of K (at. No =19) how many electrons have $m_{1} = +1$ as one of their quantum numbers?

Answer:

Potassium is in the fourth period of the table. The magnetic quantum number is an integer of from -1 to +1 through zero, i.e. 2l + 1 values.

m

0(s) 0

1(p) -1; 0; +1

2(d) -2; -1; 0; +1; +2

This shows that the quantum number $+1$ have only $p$ orbitals.

Each orbital owns 2 electrons: $2^{*}2 = 4$
