Answer:
Element
Explanation:
Because elements can be made with only one atom the rest of the answers cant be
we have to know the spin of valence electrons of carbon-14
There are four unpaired electron which are called as valence electron also.The spin of the four unpaired electron is either upfilled or down filled.
The ground state electronic configuration of C-atom is 1s²2s²2p² and one electron from 2s orbital gets excited to 2p orbital. The elctronic configuration in excited state is 1s²2s¹
.
The electron jumps because half-filled orbitals are more stable. Exchange energy is less than pairing energy.
