Question

na+nca+2 has completely filled k,l,n,m cells​

Answer 1

Answer:

na+ has completely filled K and L shells. Explain.

Answer:

Sodium is a member of the alkali metal family with lithium and potassium. Being one of the two elements in our table salt is its the biggest claim to fame.

Atomic number of sodium (Na) = 11

Number of electrons in sodium (Na) = 11

Electronic configuration of sodium [Na] = 1s2 2s2 2p6 4s1

Na+ ion has one electron less than Na atom i.e. it has 10 electrons. Therefore, 2 electrons go to K-shell and 8 electrons go to L-shell, thereby completely filling K and L shells.
