4. What type up bond would form between two atoms of chlorine (Cl), a nonmetal?
A. metallic bond
B. nonpolar covalent bond
C. polar covalent bond
D. ionic bond
E. none of these
5. If neutral atoms become positive ions, they
A. gain electrons.
B. lose electrons.
C. gain protons.
D. lose neutrons.
E. gain neutrons.
6. What is the name of the functional group --OH?
A. amino
B. methyl
C. carboxyl
D. hydroxyl
E. oxyhydry

Solution

Solution:
4(B)Two atoms of chlorine (Cl) have non polar covalent bond between them.Cl atom has 7 electrons in its outer shell.Two chlorine atoms will share one electron to complete their outer shell and form a stable Cl2 molecule.This molecule electrically neutral and known as a non -polar covalent bond .

5) (B)If neutral atoms become positive ions, they lose electrons.If neutral atom have negative charge then it gains electrons.

6)(D)The name of the functional group --OH is hydroxyl group in which oxygen atom is attached to the hydrogen atom.
