halogens
Group-17 elements have negative 1 charge. Examples are chlorine, bromine, iodine etc.
Lithium, sodium, and potassium belong to the alkali metal family in the periodic table. They share similar chemical properties such as being highly reactive and easily forming ions with a +1 charge.
The charges of atoms on the periodic table are determined by the number of protons and electrons they have. Protons carry a positive charge (+1) and electrons carry a negative charge (-1). The charge of an atom is balanced by the number of protons, which equals the number of electrons in a neutral atom.
Elements listed in the periodic table of elements are neutral; they do not have a charge. When they undergo chemical reactions they may become charged ions. There is no single most common charge for ions, but the most common are -1, -2, -3, +1, +2 and +3.
A "family" of elements means the vertical columns in the periodic table. If you look above the periodic table, there will be numbers for each row, numbered from 1 to 18. Each "family" is a column.

Potassium belongs to the alkali metal family on the periodic table. It is in Group 1, which is the first column of the periodic table.
In chemistry, a family is a group of elements that have similar properties and react in a similar way. There are 18 families in the periodic table, each with their own unique characteristics and trends. These families are commonly referred to as groups and are labeled from 1 to 18 on the periodic table.
Lithium on the periodic table is found in the first group or family and the second period. The first family is often called the alkali metal family.
more often called alkali matals, they're any element in the first(left) family(vertical) of the periodic table. they all have a charge of +1
The first family (Group 1) are the alkali metals.
