Question

electronic configuration of atom'B' given below B=1s² 2s² 2 p⁶ 3s² 3p⁶ 3d⁴ 4s² find the atomic number of B​

Answer 1

Answer:

24

Explanation:

The atomic number (Z) of an element is the number of protons found in the nucleus of every atom of that element. It is identical to the charge number of the nucleus. In an uncharged atom, the atomic number is equal to the number of electrons. Considering atom B to be uncharged, in this case, we can say that the number of electrons is equal to the number of protons. The number of electrons is the sum of electrons in all the s, p, d orbitals. Thus the sum is 24 (2+2+6+2+6+4+2=24). Hence the atomic number is 24
