This is the least massive part of the atom.
What is an electron?
100
The vertical columns of the periodic table are called these.
What are groups?
200
These are atoms of two or more different elements that are chemically bonded.
What are compounds?
200
You use this to convert from grams to moles or moles to grams.
What is the molar mass?
200
These parts of the atom make up the nucleus.
What are protons and neutrons?
