Question

elements atomic number electronic configuration of sodium chlorine bromine aluminium​

Answer 1

Answer:

group, periods

sodium -11. 1,3

chlorine-17. 17,2

bromine-35. 17,4

aluminum-13. 13,3

Answer 2

Answer:

The p orbital can hold up to six electrons. We'll put six in the 2p orbital and then put the remaining electron in the 3s. Therefore the sodium electron configuration will be 1s2 2s2 2p6 3s1.

Bromine atoms have 35 electrons and the shell structure is 2.8. 18.7. The ground state electron configuration of ground state gaseous neutral bromine is [Ar].

The electron configuration for Aluminum is 1s22s22p63s23p1.2
