Ionic vs Covalent Bonds

Why do most atoms prefer to bond with others?

• To create more protons

• To reach the most stable or lowest energy state

• To become electrically charged

• To increase their energy state

What rule states that many atoms are stable when their valence shell is filled with eight electrons?

• The neutron rule

• The octet rule

• The proton rule

• The electron rule

Which of the following elements only needs two electrons to fill its valence shell?

• Nitrogen

• Carbon

• Oxygen

• Hydrogen

What type of bond is formed through the transfer of electrons from a metal to a non-metal?

• Covalent bond

• Ionic bond

• Metallic bond

• Hydrogen bond

What is the result of an ionic bond between sodium and chlorine?

• Sodium bicarbonate

• Sodium chloride

• Sodium carbonate

• Chlorine dioxide

What type of structure do ionic compounds form?

• Amorphous solids

• Single molecules

• Crystal lattices

• Linear chains

What type of covalent bond involves an even sharing of electrons?

• Nonpolar covalent bond

• Polar covalent bond

• Ionic bond

• Metallic bond

How many covalent bonds can carbon form?

• 1

• 2

• 4

• 3

What causes a molecule to have a polar covalent bond?

• Absence of electrons

• Unequal sharing of electrons

• Equal sharing of electrons

• Transfer of electrons

What is the significance of atoms forming bonds and compounds?

• To increase atomic mass

• To form the basis of life and diversity on Earth

• To create elements

• To destroy chemical structures
