The halogens, listed in column 17 of a wide form periodic table.
combined form
Because of the lattice mobile
a group that forms anions with a -1 charge
group 1
Group that tend to form -1 ions include group VIIA
Most likely, hydrogen will form a cation, meaning it will have a positive charge of +1
The charge of group 7A elements when forming ions is -1 (negative 1).
The group 2 elements form ions with a 2+ charge. For example, Mg2+ and Ca2+. The group 16 elements form ions with a 2- charge. For example, O2- and S2-.
You need to indicate which form.
lose 2 electrons and form ions with a 2+ charge.
Elements of group 1 readily form ions having a charge of +1.
Alkali metals are found in group 1 of the periodic table. They will form ions with a 1+ charge. If you meant alkaline earth, they are found in group 2, and will form ions with a 2+ charge.
