Answer: Metals transfers electrons to nonmetals. Potassium -K transfers one electron to bromine- Br because K is located in group 1A on periodic table. Br has seven electrons and located group 7A. Both K and Br stable by gaining and losing one electron. The transfer of electrons makes metals to become + positive ions and nonmetal to become - negative ions. An ionic bond is formed, the charges attract each other.
Explanation: Metals donate, or transfer, electrons to the nonmetal.
The transfer of electrons creates a positive ion and a negative ion.
An ionic bond is formed when the charges attract each other.
