An atom of an element contains 29 electrons and 35 neutrons. Deduce:(a) the number of protons.(b) the electronic configuration of the element. |

Answer» So, a positive molecule will contain a higher number of a proton(H+ions), a negative particle will have a higher number of electrons(e-ions), and a neutral atom will contain the same number of protons & electrons. Hence, (i) For an atom to be neutral, the number of protons= number of electrons. So, Number of protons in the atom of the given element = 29 (ii) The electronic configuration of the atom is 1s2 2s2 2p6 3s2 3p6 4s1 3d10. Hence, it is the electronic configuration of copper " |
