(ii) electronic configuration of the element 'A'.

Question

An element 'A' has mass number 23 and atomic number 11. State the — (i) no. of neutrons in it's shell, (ii) electronic configuration of the element 'A'.

KnowledgeBoat · Accepted Answer

Given, mass number 23 and atomic number 11. So, Protons (P) = 11 and (i) Neutrons (n) = A - P = 23 - 11 = 12 (ii) As number of electrons (e) = 11 ∴ Electronic configuration of A = 2, 8, 1
