Explanation:
1.32 in the outtermost shell
2. The electrons in the outermost occupied shell (or shells) determine the chemical properties of the atom; it is called the valence shell. The valence shell is the outermost shell of an atom
3.Shell name Subshell name Shell max electrons
K 1s 2
L 2s 2 + 6 = 8
2p
M 3s 2 + 6 + 10 = 18
4.K denotes the first shell (or energy level), L the second shell, M, the third shell, and so on. In other words, the KLMN(OP) notation only indicates the number of electrons an atom has with each principal quantum number (n). ... When l=0, we have an s subshell, which has one orbital ml=0, with room for two electrons.
