oxygen
hydrogen
nitrogen
carbon dioxide
argon
question 12 (1 point)
which best describe a molecular compound?
a substance composed of non - metals.
a chemical compound stabilized by covalent bonds.
a connection between atoms resulting in the sharing of electrons.
a chemical compound held together through electrostatic forces.
all of the above are molecular compounds.

Explanation:

Question 11

Argon is a noble gas. Noble gases have a full valence shell of electrons (8 electrons for argon, which follows the octet rule). This full valence shell makes them very stable and they do not readily form bonds with other atoms. Oxygen (\(O_2\) is a common form), hydrogen (\(H_2\)), nitrogen (\(N_2\)) form di - atomic molecules through covalent bonding. Carbon dioxide (\(CO_2\)) has covalent bonds between carbon and oxygen atoms.

• A molecular compound is a chemical compound stabilized by covalent bonds.
• While molecular compounds are often composed of non - metals (but this is not the most precise definition as some compounds with a few metal - non - metal combinations can also have covalent character in some cases), the key defining feature is the covalent bond.
• A connection between atoms resulting in the sharing of electrons is a description of a covalent bond, but a molecular compound is the compound itself, not just the bond.
• A chemical compound held together through electrostatic forces is an ionic compound.

Answer:

argon
