Question

An atom of an element contains 29 electrons and 35 neutrons . no. of paired electorns and unpaired

Answer 1

Answer:

Number of Paired electrons: 28

Number of Unpaired electrons: 1

Explanation:

Electronic Config: 1s^{2} 2s^{2} 2p^{6} 3s^{2} 3p^{6} 4s^{2} 3d^{9}

In the d sub shell there is only one electron without its opposite spin and does not have a pair. Therefore there is only 1 unpaired electrons and the rest of the electrons are paired that is 28.
