Chemical Bonding Flashcard

Front

What is a covalent bond?

Back

A type of bond that occurs when two atoms share a pair of electrons.

Front

Define a chemical bond.

Back

A lasting attraction between atoms, ions, or molecules.

Front

Why do chemical bonds form?

Back

To fill up the outer shell and become more stable.

Front

What is an ionic bond?

Back

A chemical bond formed between two ions with opposite charges.

Front

When do covalent bonds form in chemical compounds?

Back

When pairs of electrons are shared between two nonmetal atoms.

Front

What is a nonpolar covalent bond?

Back

A type of covalent bond where electrons are shared equally between two atoms.

Front

What is a polar covalent bond?

Back

A type of covalent bond where electrons are shared unequally between two atoms.

Front

What is electronegativity?

Back

The tendency of an atom to attract electrons in a bond.

Front

What is the octet rule?

Back

Atoms tend to form bonds in such a way that they have eight electrons in their outer shell.

Front

What is a metallic bond?

Back

A bond formed by the attraction between positively charged metal ions and the electrons in a metal.
