Question

First Ten Elements and Noble Gas Configuration.

a) 1s^1
b) 1s^2
c) 1s^22s^22p^63s^2
d) 1s^22s^22p^63s^22p^6

Answer 1

The first ten elements and their noble gas configurations are provided. Noble gas configuration is a shorthand notation for electron configurations in which the elemental symbol of the last noble gas is used, followed by the configuration of the remaining electrons.

Step-by-step explanation:

The first ten elements and their noble gas configurations are:

1. a) 1s22s22p5
2. b) [Ne] 3s2
3. c) [Ne] 3s23p3
4. d) [Ne] 3s23p6

Noble gas configuration is a shorthand notation for electron configurations. It consists of the elemental symbol of the last noble gas prior to that atom, followed by the configuration of the remaining electrons. For example, the noble gas configuration of sodium (Na) is written as [Ne] 3s1.
