Question
An atom of an element contains 29 electrons and 35 Deutrons. Deduce (i) the number of protons and (ii) the electronic configuration of the element.
Solution
We know for neutral atom,
Number of protons = Number of electrons = 29
Thus atomic number of the element = 29
Electronic configuration of element (Z = 29) can be represented as 29Z ;
1s22s22p63s23p64s13d10
or [Ar]184s13d10
