Covalent Compounds Flashcard

Front

What is a covalent bond?

Back

A covalent bond is a chemical bond formed when two atoms share one or more pairs of electrons.

Front

What types of elements typically form covalent bonds?

Back

Covalent bonds typically form between nonmetals.

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.

Front

What is a molecule?

Back

A molecule is a group of two or more atoms bonded together by covalent bonds.

Front

What is a chemical formula?

Back

A chemical formula shows the number and type of each atom in a compound.

Front

What does a coefficient in a chemical equation indicate?

Back

A coefficient indicates the number of molecules or moles of a substance in a reaction.

Front

What is the significance of subscripts in a chemical formula?

Back

Subscripts indicate the number of atoms of each element in a molecule.

Front

What is electronegativity?

Back

Electronegativity is the tendency of an atom to attract electrons in a chemical bond.

Front

What is a polar covalent bond?

Back

A polar covalent bond is a type of covalent bond where electrons are shared unequally between atoms, resulting in partial charges.

Front

What is a nonpolar covalent bond?

Back

A nonpolar covalent bond is a type of covalent bond where electrons are shared equally between atoms.
