Front

Water is an example of a(n) ____ compound.

Back

polar covalent

Front

What is the electron configuration for silicon?

Back

1s² 2s² 2p⁶ 3s² 3p²

Front

Type of compound in which there is little to no difference in electronegativity between atoms, such as N₂?

Back

nonpolar covalent

Front

Which of the following is a nonmetal?

Back

oxygen (O)

Front

Which group is completely stable and will not bond with other atoms?

Back

noble gases

Front

Define a polar covalent bond.

Back

A bond where electrons are shared unequally between two atoms, resulting in a molecule with a slight charge difference.

Front

What is the significance of the octet rule in chemistry?

Back

Atoms tend to bond in such a way that they have eight electrons in their valence shell, achieving stability.

Front

Describe the characteristics of ionic compounds.

Back

Ionic compounds are formed from the electrostatic attraction between oppositely charged ions and typically have high melting and boiling points.

Front

What distinguishes a nonpolar covalent bond from a polar covalent bond?

Back

Nonpolar covalent bonds occur between atoms with similar electronegativities, resulting in equal sharing of electrons.

Front

Identify the main characteristics of noble gases.

Back

Noble gases are colorless, odorless, and tasteless gases that are nonreactive due to having a full valence shell.
