Physical Science Ch. 18 Chemical Bonds Quiz

What are the two main types of chemical bonds?

• Hydrophobic bonds and hydrophilic bonds

• Ionic bonds and covalent bonds

• Metallic bonds and hydrogen bonds

• Van der Waals bonds and polar bonds

What is ionic bonding and how does it occur?

• Ionic bonding occurs when atoms repel each other due to similar charges

• Ionic bonding is the sharing of electrons between atoms

• Ionic bonding is the result of covalent bonds between atoms

• Ionic bonding is the electrostatic attraction between oppositely charged ions, and it occurs when one atom transfers one or more electrons to another atom.

What is covalent bonding and how does it differ from ionic bonding?

• Covalent bonding involves the attraction of opposite charges between atoms.

• Covalent bonding involves the formation of a crystal lattice structure.

• Covalent bonding involves the sharing of electrons between atoms.

• Covalent bonding involves the transfer of electrons between atoms.

What are the properties of ionic compounds?

• Medium melting and boiling points, conductivity in solid state, and the formation of amorphous lattices

• High melting and boiling points, conductivity in molten or aqueous state, and the formation of crystal lattices

• Low melting and boiling points, non-conductivity in any state, and the formation of gaseous lattices

• High melting and boiling points, non-conductivity in any state, and the formation of liquid lattices

What are the properties of covalent compounds?

• Formed by sharing of electrons between atoms, low melting and boiling points, usually insoluble in water

• Formed by transfer of electrons between atoms, high melting and boiling points, usually soluble in water

• Formed by sharing of protons between atoms, high melting and boiling points, usually insoluble in water

• Formed by sharing of electrons between atoms, high melting and boiling points, usually soluble in water

What are some examples of substances that form ionic bonds?

• Carbon dioxide, water, nitrogen gas

• Iron, copper, aluminum

• Hydrochloric acid, sulfuric acid, nitric acid

• Sodium chloride, magnesium oxide, calcium fluoride

What are some examples of substances that form covalent bonds?

• Oxygen, nitrogen, hydrogen

• Water, methane, carbon dioxide

• Iron, copper, silver

• Sodium chloride, sulfuric acid, ammonia

How do you determine the type of bond formed between two atoms?

• By counting the number of electrons

• By looking at the color of the atoms

• By measuring the size of the atoms

• By seeing if it is a metal and a nonmetal or 2 nonmetals

What is the difference between polar and nonpolar covalent bonds?

• Nonpolar covalent bonds have unequal sharing of electrons.

• Polar covalent bonds have equal sharing of electrons.

• Polar covalent bonds have unequal sharing of electrons.

• Polar covalent bonds have no sharing of electrons.

What is the name for a positively charged ion?

• anion

• ion

• cation

• plus ion
