WebThe elements that form bonds by donating electrons are called cations. Aluminum donates the electron of the last shell to form bonds and turns into an aluminum ion(Al 3+). That is, aluminum is a cation element. Al – 3e – → Al 3+ The electron configuration of aluminum ion(Al 3+) is 1s 2 2s 2 2p 6. WebAtomic Number – Protons, Electrons and Neutrons in Gold Gold is a chemical element with atomic number 79 which means there are 79 protons in its nucleus. Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z.
