Multiple Choice

An atom has the configuration 1s² 2s² 2p³. Will it gain or lose electrons?

It will lose 5 electrons

It will gain 2 electrons

It will gain 3 electrons

It will lose 3 electrons

It will gain 5 electrons

Reorder

Put these in the correct order

Multiple Choice

Which of the following is the electron configuration for neon?

Explanation Slide...

Add up all of the electrons - it has 7 electrons, so it must be nitrogen. Nitrogen has 5 valence electrons, but it wants 8. Therefore, it will steal 3 more electrons to form a charge of -3.
