Question

Explain the process of ionic bond formation between K

(potassium, a metal) and Br (bromine, a nonmetal).
I

Answer 1

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.

Answer 2

Metals transfers electrons to nonmetals. So K transfers one electron to Br because K is located at 1A in the periodic table. Br has seven electrons, now both K and Br are stable by gaining and losing one electron. The transfer of electrons makes metals to become positive ions and nonmetal to become negative ions. When an ionic bond is formed, the charges attract each other.
