Older houses donât have their data inputted into the database as of yet. If youâre lucky enough to live in one of these older buildings you should check as to whether your property is in the database. If it isnât, your housing deed documents are important. Keep them safe and keep them secure.
In terms of non-metals, the electrons are held tightly by the nucleus. Therefore nonmetals are very unwilling to give their electrons away. Nonmetals don't donate electrons as easily as metals, so society and chemists from the early ages distinguished between metals and nonmetals, Regards, Mike
Nonmetals also have high electron affinity. This means that it is energetically favorable to add an electron to a nonmetal. So, nonmetals can be easily reduced. Metals tend to have low electron affinity so it is more difficult to add electrons (or reduce them). In short: Metals have low ionization energies and low electron affinities so they are readily oxidized. Nonmetals have high ionization energies and high electron affinities so they are readily reduced.
