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

Explanation

Since the atom contains 29 electrons , the atomic number of element is 29
`therefore` The number of protons is also 29
The element is copper
It electronic configuration is `1s^(2)2s^(2)2p^(6)3s^(2)3p^(6)3d^(10)4s^(1)`.
