Periodic table

What are the vertical columns on the periodic called?

• groups

• metals

• nonmetals

• periods

• metalloids

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 are the horizontal rows on the periodic table called?

• groups

• periods

• nonmetals

• metals

• metalloids

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

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

• The number of energy levels

The positively charged subatomic particle contained in the nucleus of an atom

• electron

• proton

• neutron

• matter

How do you calculate the number of neutrons?

• Mass - Atomic number = Neutrons

• Atomic number = Neutrons

• Mass = Atomic number - Neutrons

How many valence electrons does the element have?

• 4

• 3

• 2

• 1

What does the 6 represent?

• element name

• atomic number

• chemical symbol

• atomic mass

What are valence electrons?

• electrons located on the first energy level

• electrons located on the outer energy level

• any of an atom's electrons

• electrons not attached to any atom

What group and period does this element belong in?

• Any of an atom's electrons

• period 1 and group 3

• period 3 and group 2

• period 3 and group 1
