Which group will have a charge of +2 when ionized? O A. Alkali Earth metals
OB. Halogens
C. Alkali metals
D. Noble gases

Alkaline earth metals

Explanation:

Group 2 has 2 valence electrons that they lose when being ionized, thus making  their charge 2+.

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.
