240 ÷ 2 = 120
To determine how many 2s go into 30, you divide 30 by 2. The calculation is 30 ÷ 2 = 15. Therefore, there are 15 twos in 30.
96 ÷ 2 = 48
64 ÷ 2 = 32
214 ÷ 2 = 107
Exactly 45 of them

2. Because 2 squared (2x2) equals 4
thirty 60 / 2 = 30
The 2s orbital can hold a maximum of 2 electrons.
