Chemical Bonding

Front

What is the octet rule?

Back

Elements gain or lose electrons to fill their outer shell with 8 electrons.

Front

Why do elements want to bond?

Back

To be like the noble gases which are stable with full valence electron shells.

Front

What is a covalent bond?

Back

A bond between atoms where electrons are shared.

Front

What is a compound molecule?

Back

When different atoms bond together.

Front

What type of bond is formed between a metal and a nonmetal?

Back

Ionic.

Front

What is an ionic bond?

Back

A bond formed when one atom transfers electrons to another atom.

Front

What are valence electrons?

Back

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

Front

What is the difference between a polar and nonpolar covalent bond?

Back

Polar covalent bonds have unequal sharing of electrons, while nonpolar covalent bonds have equal sharing.

Front

What is electronegativity?

Back

A measure of an atom's ability to attract and hold onto electrons.

Front

What is a molecule?

Back

A group of two or more atoms bonded together.
