- Atoms can lose or gain electrons. When they do, they form charged particles called ions: if an atom loses one or more electrons, it becomes a positively charged ion if an atom gains one or more electrons, it becomes a negatively charged ion

There are four ways to find the charge of an element: 1. Use the periodic table. The usual charge of an element is common to its group. Group 1 (Alkali Metals): 1+ Group 2 (Alkaline Earth Metals): 2+ Groups 3-12 (Transition Metals): Variable positive charges Lanthanide and Actinide Series: Variable positive charges Group 13: 3+ Group 14: 4+ or 4- G...
In many texts, the terms charge (or formal charge), valence, and oxidation number are used interchangeably. These three terms are related, but have slightly different definitions: 1. Charge (Formal Charge): Charge is the electrical charge of an atom when all of its ligands are removed homolytically. In homolytic cleavage, electrons sharing a bondar...

Atoms that lose electrons acquire a positive charge because they are left with fewer negatively charged electrons to balance the positive charges of the protons in the nucleus. Positively charged ions are called cations. Most metals become cations when they make ionic compounds.
Jul 18, 2022 · Protons are a type of subatomic particle with a positive charge. Protons are bound together in an atom's nucleus as a result of the strong nuclear force. Neutrons are a type of subatomic particle with no charge (they are neutral).
Jul 29, 2022 · Protons have a positive electrical charge of one \(\left( +1 \right)\) and a mass of 1 atomic mass unit \(\left( \text{amu} \right)\), which is about \(1.67 \times 10^{-27}\) kilograms. Together with neutrons, they make up virtually all of the mass of an atom.
