2s - 12 + 2s = 4s - 124s - 12 = 4s - 124s = 4ss = s==========this is an identity and any number can be s
There is only one 2s orbital in an atom.
Sodium (Na) has an atomic number of 11, meaning it has 11 electrons. The electron configuration of sodium is 1s² 2s² 2p⁶ 3s¹. In the second shell, which includes the 2s and 2p subshells, there are 8 electrons (2 in the 2s and 6 in the 2p).
It is a mixed number.
To determine how many 2s go into 18, you can divide 18 by 2. When you perform the calculation, 18 ÷ 2 equals 9. Therefore, there are nine 2s in 18.
The 2s sublevel can hold a maximum of 2 electrons.

To find how many 2s are in a number, you need to divide it by 2. In this case we have 232, so do: 232/2 = 116. Therefore there are 116 twos in 232.
Seven of them.
The difference between the number of 2s and the number of 4s in a sum.
