... Neutral atoms contain equal numbers of protons (+) and electrons (-). Because of this, you know that neutral atoms of lithium, beryllium, boron and carbon also have 3, 4, 5, and 6 electrons respectively. When two elements are near one another they often react. Much like reactions between two people, ...
