Electrons in Atoms Neon (Ne)
In chemical reactions,
atoms tend to gain or
lose electrons so that
their outer shells are full.
The first shell around the
nucleus is full when it
contains two electrons.
The second shell is filled
when it has eight
electrons. Neon has two
full shells.
Complete the model of
a neon atom by
dragging and dropping
electrons onto the rings
that represent each shell.
