1.	An atom of an element contains 29 electrons and 35 neutrons. Deduce (i) the number of protons and the (ii) the electronic configuration of the element.
Answer» No. of electrons in the atom of an element = 29 No. of neutrons in the atom of an element = 35 (i) Number of protons = 29 (ii) Electronic configuration (At. no = 29) = 1s² 2s² 2p⁶ 3s² 3p⁶ 3d¹⁰ 4s¹.

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

Answer»

No. of electrons in the atom of an element = 29

No. of neutrons in the atom of an element = 35

(i) Number of protons = 29

(ii) Electronic configuration (At. no = 29)

= 1s² 2s² 2p⁶ 3s² 3p⁶ 3d¹⁰ 4s¹.
