Chemical Bonding

Why do atoms tend to lose or gain electrons during chemical bonding?

• to attain beauty

• to attain stability

• to become reactive

• to attain malleability

What is the primary reason for the formation of ionic bonds between atoms?

• to share electrons

• to transfer electrons

• to create a magnetic field

• to form covalent bonds

What type of bond is formed when two atoms share electrons equally?

• ionic bond

• polar covalent bond

• nonpolar covalent bond

• metallic bond

What is the characteristic feature of a polar covalent bond?

• equal sharing of electrons

• unequal sharing of electrons

• transfer of electrons

• formation of metallic bonds

What happens to the charge of an atom when it loses an electron?

• it becomes neutral

• it becomes positively charged

• it becomes negatively charged

• it remains unchanged
