The element Z = 114 has been discovered recently. It will belong to which of the following family group and electronic configuration?

Solution & Step-by-step Explanation

The atomic number Z = 114 .Radon (R n) is the noble gas with Z = 86 .Following the Aufbau principle:The configuration fills as: [R n] 7 s^{2} 5 f^{14} 6 d^{10} 7 p^{2} .Total electrons = 86 (R n) + 2 + 14 + 10 + 2 = 114 .Since the valence shell configuration is n s^{2} n p^{2} (specifically 7 s^{2} 7 p^{2}), it belongs to Group 14, which is the Carbon family.

Try it yourself before checking the explanation above.
