Week 1 Quiz - Intro to Chemistry

What are the three main groups of the periodic table?

• groups

• metal

• nonmetals

• metalloids

• periods

What do the vertical columns on the periodic table tell us?

• The number of orbitals

• The number of valence electrons (electrons on the outer most shell)

What do the horizontal rows on the periodic table tell us?

• The number of orbitals

• The number of valence electrons (the electrons on the outer most shell)

What does the number of proton tell us?

• electrons

• atomic number

• atomic mass

• neutrons

How do you calculate the number of neutrons? *

• Mass = Atomic number - Neutrons

• Mass - Atomic number = Neutrons

• Atomic number = Neutrons
