Chemical Bonding Review

Front

What is a valence shell?

Back

The outermost shell of an atom that contains the valence electrons, which are involved in chemical bonding.

Front

How many valence electrons does Neon have?

Back

8 valence electrons.

Front

What is the octet rule?

Back

Atoms tend to bond in such a way that they have eight electrons in their valence shell, achieving a stable electron configuration.

Front

Why are atoms more stable when bonded together?

Back

Bonding allows atoms to achieve a full valence shell, which lowers their energy and increases stability.

Front

What type of bond is present in CCl4?

Back

CCl4 has only single covalent bonds; it has no double bonds.

Front

What is a covalent bond?

Back

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

Front

What is the number of valence electrons for Oxygen?

Back

6 valence electrons.

Front

What is an ionic bond?

Back

A chemical bond formed through the transfer of electrons from one atom to another, resulting in the formation of charged ions.

Front

What happens to the valence electrons in an ionic bond?

Back

One atom loses electrons (becoming a positive ion) while another atom gains those electrons (becoming a negative ion).

Front

What is the significance of the periodic table in understanding chemical bonding?

Back

The periodic table helps predict how atoms will bond based on their position, which indicates their number of valence electrons.
