Question

Explain how the element sodium is
monovalent.​

Answer 1

Answer:

Explanation:

Sodium has 1 electron in its outer most shell and to acquire noble gas configuration it will lose one electron and hence sodium is monovalent. ... Sodium is a metal with atomic number 11. ... In order to get stability by acquiring octet configuration sodium prefers to loose 1 electron.

Answer 2

1) The number of protons or electrons (atomic number) in sodium (Na) atom is 11. Therefore the electronic configuration of sodium atom is (2,8,1).

2) In chemical reaction, sodium atom has the capacity to give away 1e- from its outermost orbit to form Na+ ion which stable electronic configuration (2,8).

3) As sodium atom gives away 1e- and a cation of sodium is formed, hence the valency of sodium is 1 and therefore the element sodium is monovalent.
