What Type Of Element Forms An Anion Charges?
The goal of every element in the periodic table is to stabilize itself. An atom is stable if it has a complete octet in its last valence shell. In very primary terms, every element has the following distribution of electrons through the different shells: 2, 8, 8, 8,……x x represents the number of electrons in the last shell. Remember that the goal is to gain an octet (8 electrons) for the last shell. So, an atom would lose electrons so that its last electron shell is empty. In this way, the second last shell, which has eight electrons, would actually become the last shell in the atom. Sometimes, an electron would gain an electron so that when added to other electrons in the last shell, the total number is eight. Its behavior is determined by what the number of electrons is in the last shell. Mostly atoms that have one or two electrons tend to lose electrons because it is more feasible than gaining 7 -6 electrons.
