Question

2/14
each box on the periodic table represents
one atom of that element
one electron of that element
one molecule of that element
one chemical reaction of that element

Explanation:

The Periodic Table's boxes represent elements, and each box corresponds to one atom of the element (elements are made of atoms). Electrons are sub - atomic particles, molecules are for compounds or diatomic elements (not the basic box representation), and a box doesn't represent a chemical reaction. So the correct option is "One atom of that element".

Answer:

One atom of that element
