Flashcards

What is the charge of alkali metals?

Group 1 elements are called alkali metals and always have a +1 charge. This means they lose one electron to become stable.

What is the charge of alkaline earth metals?

Group 2 elements are called alkaline earth metals and always have a +2 charge. This means they lose two electrons to become stable.

What is the typical charge of group 3 elements?

Group 3 elements typically have a +3 charge. This means they lose three electrons to become stable.

What is the charge of noble gases?

Group 18 elements are called noble gases and are very stable. They have a full outer shell of electrons and do not need to gain or lose any electrons to become stable, so they have no charge.
