An atom of an element contains 29 electrons and 35 neutrons. Deduce (i) the number of protons and (ii) the electronic configuration of the element.

(i)No.protons = no.electrons in a neutral atom.
The number of protons in the atoms of the element is 29.

(ii)The electronic configuration of this element (atomic number 29) is 1s ² 2s ² 2p ⁶ 3s ² 3p ⁶ 4s ¹ 3d ¹⁰ . The element is copper (Cu).
