21 lip 2022 · Any ion with a positive charge is referred to as a cation. Nonmetals, on the other hand, tend to gain electrons. This means the ion formed from a nonmetal atom with end up with more electrons than protons and have an overall negative charge. An anion is the general name given to any negatively charged ion. Hydrogen behaves a little differently ...

If the charge is a single positive or negative one, the number 1 is not written; if the magnitude of the charge is greater than 1, then the number is written before the + or − sign. An element symbol without a charge written next to it is assumed to be the uncharged atom.
Ion, any atom or group of atoms that bears one or more positive or negative electrical charges. Positively charged ions are called cations; negatively charged ions, anions. Ions migrate under the influence of an electrical field and are the conductors of electric current in electrolytic cells.
An ion (/ ˈaɪ.ɒn, - ən /) [1] is an atom or molecule with a net electrical charge. The charge of an electron is considered to be negative by convention and this charge is equal and opposite to the charge of a proton, which is considered to be positive by convention.
Remember that ions are formed only when electrons move from one atom to another; a proton never moves from one atom to another. Compounds formed from positive and negative ions are called ionic compounds. Individual atoms can gain or lose electrons. When they do, they become monatomic ions.
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.
An ion is an atom or molecule with either a positive or negative electrical charge. An ion has a charge because the number of protons does not equal the number of electrons; to find the number of protons and electrons, check out this article.
