8 valence electrons.

Front

If electrons are shared equally in a bond, what type of bond is it?

Back

Non-polar covalent bond.

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 covalent bond?

Back

A bond formed when two atoms share one or more pairs of electrons.

Front

What is the difference between polar and non-polar covalent bonds?

Back

Polar covalent bonds have unequal sharing of electrons, while non-polar covalent bonds have equal sharing.

Front

What is ionization energy?

Back

The energy required to remove an electron from an atom.

Front

What is the significance of electronegativity in bond formation?

Back

Electronegativity determines how electrons are shared between atoms in a bond.
