Chemistry Part One- Modified (re:2022)

The Period Table is arranged how?

• By element's discovery

• By Atomic Number

• Alphabetically

• By Physical Properties

What is the difference between Atomic Number and Atomic Mass

• Atomic Number is the number protons and Atomic Mass is the average of isotopes

• Atomic Number is the average of isotopes and Atomic Mass is the number of protons

• Atomic Number is the number of electrons and Atomic Mass is the actual mass of an atom

• Atomic Number is the order of discovery and Atomic Mass is the number of protons

Periods on the Period Table tell us what?

• The number of valence electrons

• The state of matter

• The number of electron shells
