Energy level formula

2n(2) (2n Squared)

What is the total number of electrons needed to fill the second main energy level?

8. Because 2nsquared=2(2)squared = 8

Cation

Positive charge

Anion

Negatively Charged

There are 7 energy levels and 7 periods on the periodic table

True

If an atom is positively charged it...

Lost one electron

If an atom is negatively charged it...

Gained one electron

Exponents

Number of electrons

A single orbital holds only two electrons

True

Noble Gases are...

Relatively unreactive and have a complete outer shell.
