When sodium loses its 3s electron, it is then left with a complete 2s
2p
shell, just like neon.

Na ∙ → [Na]
A sodium atom loses one electron to become a positively charged sodium ion.
Positively charged ions such as sodium ions have a complete set of eight electrons in their outermost shell.
However, rather than draw eight dots around the symbol for a positive ion, we instead draw zero dots to
show that the ion was created through the loss of electrons.
Draw the appropriate number of dots around the following symbols to create correct electron dot
structures for the following ions.
