A Model Atom
In this lab, you will examine the relationship between an element’s
location on the periodic table and its number of valence electrons.
You will use this information to draw models of three elements and
their valence shells

Answer 1

Let's choose sodium (Na) as an example, which is in period 3.

Sodium has 1 valence electron.

The element next to sodium on the periodic table is magnesium (Mg), also in period 3.

Magnesium has 2 valence electrons, which is one more than sodium.
