WebAug 21, 2024 · It is a stable compound and is non-radioactive. Nitrogen-14 has the most practical uses, and is found in agricultural practices, food preservation, biochemicals, and biomedical research. Nitrogen-14 is found in abundance in the atmosphere and among many living organisms. It has 5 valence electrons and is not a good electrical conductor. WebFor instance, consider the compound NaCl. We know that the valency of sodium (Na) is +1 and Chlorine (Cl) is -1. Both sodium and chlorine have to gain one electron and lose one electron respectively to achieve stable outermost orbit. Therefore, sodium donates an electron and chlorine accept the same electron. This is how the valency is determined.
