Chem Semester 1 Review

Front

What is a non-polar covalent bond?

Back

A non-polar covalent bond is a type of chemical bond where electrons are shared equally between two atoms.

Front

What is a polar covalent bond?

Back

A polar covalent bond is a type of chemical bond where electrons are shared unequally between two atoms, resulting in a partial positive charge on one atom and a partial negative charge on the other.

Front

What particles are found in the nucleus of an atom?

Back

The nucleus of an atom contains protons and neutrons.

Front

What are ions?

Back

Ions are atoms that have gained or lost electrons, resulting in a net electrical charge.

Front

What is a metallic bond?

Back

A metallic bond is the attraction between positive metal ions and free-floating electrons, allowing for conductivity and malleability.

Front

What is the definition of a polar molecule?

Back

A polar molecule is a molecule that has a net dipole moment due to the presence of polar bonds, resulting in a partial positive and negative charge.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons from one atom to another, while covalent bonds involve the sharing of electrons between atoms.

Front

What is electronegativity?

Back

Electronegativity is a measure of an atom's ability to attract and hold onto electrons in a chemical bond.

Front

What is a hydrogen bond?

Back

A hydrogen bond is a weak attraction between a hydrogen atom covalently bonded to an electronegative atom and another electronegative atom.

Front

What is the significance of the octet rule?

Back

The octet rule states that atoms tend to bond in such a way that they have eight electrons in their valence shell, achieving a stable electron configuration.
