Why does chemistry happen?! Element Stability and the Octet Rule!

The video explains why ions form and elements bond, focusing on the concept of stability. Elements aim for a full outer shell of valence electrons, often following the octet rule, except for hydrogen and helium. Stability can be achieved by transferring or sharing electrons, forming ionic or covalent bonds. Examples include sodium losing an electron to become Na+ and chlorine gaining an electron to become Cl-. Helium is stable with two electrons, as are other noble gases.

What is the main reason elements form bonds?

• To increase their mass

• To become stable

• To change their color

• To decrease their size

What is the octet rule?

• Elements want to have eight neutrons

• Elements want to have eight protons

• Elements want to have eight valence electrons

• Elements want to have eight energy levels

How does sodium achieve stability?

• By losing seven electrons

• By gaining seven electrons

• By losing one electron

• By gaining one electron

What happens when chlorine becomes stable?

• It loses one electron

• It gains one electron

• It loses seven electrons

• It gains seven electrons

Why are noble gases like helium considered stable?

• They have a full outer shell of two electrons

• They have a full outer shell of ten electrons

• They have a full outer shell of eight electrons

• They have no electrons
