Bonding and Lewis structures

Front

What is a polar covalent bond?

Back

A type of chemical bond where two atoms share electrons unequally, resulting in a partial positive charge on one atom and a partial negative charge on the other.

Front

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

Back

+2

Front

Which element has a higher electronegativity: Nitrogen (N) or Arsenic (As)?

Back

Nitrogen (N) has a higher electronegativity than Arsenic (As).

Front

What type of bond occurs between metals and nonmetals?

Back

Ionic bond.

Front

What is a metallic bond?

Back

A type of bond where electrons are shared in a 'sea' of electrons, allowing for conductivity and malleability.

Front

Define electronegativity.

Back

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

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 non-polar covalent bond?

Back

A type of bond where two atoms share electrons equally, resulting in no charge separation.

Front

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

Back

It becomes negatively charged.

Front

What is the octet rule?

Back

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