Answer:
Group 1A
Ionic bond or electrostatic bond
Explanation:
- Bond is a type of energy that is responsible to hold two or more same or different types of atoms.
- On the basis of bond formation, the bond may be an ionic bond, covalent bond, coordinate bond and some other.
- Group 7A elements like chlorine, bromine and some other has 7 electrons in its outermost shell so it receives 1 electron to complete its octet and thus the formation of chloride or other ions takes place having a negative charge.
- So 1A group like sodium and some other has 1 electron in its outermost shell and thus loses 1 electron to obtain octane and thus form a positive ion.
- Thus attraction takes place between positive ions like sodium ions and negative ions like chloride ions and a bond is formed that is known as an ionic bond or electrostatic bond.
