Unit 3: Chemical Bonding Grade Replacement

Front

What are covalent bonds?

Back

Covalent bonds are chemical bonds formed between two non-metal atoms that share pairs of electrons.

Front

What type of bond is formed between two fluorine atoms?

Back

A covalent bond, specifically a nonpolar covalent bond, since both atoms have the same electronegativity.

Front

Which elements typically form ionic compounds?

Back

Ionic compounds are typically formed between metals and non-metals, such as lithium (Li) and sulfur (S).

Front

What charge does an atom have if it loses two electrons?

Back

If an atom loses two electrons, it will have a +2 charge.

Front

How do intermolecular forces affect boiling points?

Back

Substances with stronger intermolecular forces have higher boiling points than those with weaker intermolecular forces.

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 polar covalent bond?

Back

A polar covalent bond is a type of bond where electrons are shared unequally between two non-metal atoms, resulting in a molecule with a slight charge.

Front

What is an ionic bond?

Back

An ionic bond is a chemical bond formed through the transfer of electrons from one atom to another, typically between a metal and a non-metal.

Front

What is the difference between a polar and nonpolar molecule?

Back

Polar molecules have a partial positive and negative charge due to unequal sharing of electrons, while nonpolar molecules have an even distribution of charge.

Front

What happens to the charge of an atom when it gains electrons?

Back

When an atom gains electrons, it becomes negatively charged.
