Which shell is occupied by the last electron of Neon?
K shell
L shell
M shell
N shell
Electronic configuration of Neon- 2,8.
Hence, the last electron is filled in Shell- L.
Which element has :
(a) two shells, both of which are completely filled with electrons?
(b) the electronic configuration 2, 8, 2?
(c) a total of three shells, with four electrons in its valence shell?
(d) a total of two shells, with three electrons in its valence shell?
(e) twice as many electrons in its second shell as its first shell?
