Question

ways in which ions may form include ________. select all that apply a exposure to radiation b transfer of electrons between atoms c sharing of electrons between atoms d transfer of protons between atoms

Explanation:

Ions are formed when atoms gain or lose electrons. Exposure to radiation can cause electrons to be ejected from atoms, forming ions. The transfer of electrons between atoms also results in the formation of ions. Sharing of electrons between atoms forms covalent bonds, not ions. Protons are not transferred between atoms to form ions as they are in the nucleus and not easily mobile in chemical - bonding processes.

Answer:

A. exposure to radiation
B. transfer of electrons between atoms
