Front

What is the difference between equal and unequal sharing of electrons?

Back

Equal sharing results in nonpolar covalent bonds, while unequal sharing results in polar covalent bonds.

Front

What is a Chemical bond?

What is a hydrate?

Back

A compound that contains water molecules within its crystal structure.

Front

What is a covalent bond?

Back

A chemical bond formed by the sharing of electrons between atoms.

Front

What is an ionic bond?

Back

A chemical bond formed through the transfer of electrons from one atom to another.

Front

What are valence electrons?

Back

Electrons in the outermost shell of an atom that are involved in chemical bonding.

Front

What is the octet rule?

Back

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

Front

What is a polar molecule?

Back

A molecule that has a partial positive charge on one end and a partial negative charge on the other end.
