What does a subscript in a chemical formula represent?

• The number of molecules

• The charge of the ion

• The number of atoms of the element in the molecule

• The atomic number of the element

How can you determine whether an element will form an ionic or covalent compound using the periodic table?

• By looking at the element's atomic number

• By checking the element's position in the periodic table

• By observing the color of the element on the periodic table

• By the size of the element's atomic mass

Which type of bond is formed by the sharing of electrons between atoms?

• Metallic bond

• Ionic bond

• Covalent bond

• Hydrogen bond

What is the primary difference between ionic and covalent compounds?

• Ionic compounds are usually gases at room temperature, while covalent compounds are liquids.

• Ionic compounds involve the transfer of electrons, while covalent compounds involve the sharing of electrons.

• Ionic compounds can only be formed by metals, while covalent compounds are formed by nonmetals.

• Ionic compounds dissolve in water, while covalent compounds do not dissolve.
