These are what form chemical bonds as atoms share or take them from one another. They orbit the nucleus and have a negative charge (but they are still happy about things in general).

• electrons

• electron clouds

• protons

• neutrons

This is the central region of an atom and where protons and neutrons hang out (but the protons and neutrons still follow proper social distancing rules!).

• nucleus

• electron cloud

• The Periodic Table of Elements

• atomic number

This is a list of the 118 known elements that exist (and a picture of it is on this quiz!).

• The Periodic Table of Elements

• The Student Faculty Handbook

• Facebook

• Wikipedia

This tells you how many protons are in each atom of a specific element and how many electrons there are in each unreacted atom from that element.

• atomic number

• atomic mass

• chemical formula

• chemical symbol

This is the written out expression for a substance and contains each element in it and the number of atoms for that element.
