What type of bond shares electrons equally?

Back

A nonpolar covalent bond shares electrons equally between atoms.

Front

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

Back

If an atom loses two electrons, it will have a +2 charge.

Front

What happens to an atom when it loses an electron?

Back

When an atom loses an electron, it becomes a positive ion.

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 between atoms.

Front

What is an ion?

Back

An ion is an atom or molecule that has a net electrical charge due to the loss or gain of one or more electrons.

Front

What is a polar covalent bond?

Back

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

Front

What is the octet rule?

Back

The octet rule states that atoms tend to bond in such a way that they have eight electrons in their valence shell, achieving a stable electron configuration.

What is the role of electrons in chemical bonding?

Back

Electrons, particularly valence electrons, play a crucial role in chemical bonding by being shared or transferred between atoms.
