Which group of elements has the lowest ionization energy?
Group 1
Group 2
Group 3
Group 4
Group VIII A elements are called ________________
Alkali metals
Transition metals
Halogen
Noble gases
Group I A elements (not including hydrogen) are called ________________

Which statement about subatomic particles is true?
Protons, neutrons, and electrons all have about the same mass.
Unlike protons or neutrons, electrons have no mass.
Neutrons have no charge and no mass.
An electron has far less mass than either a proton or neutron.
To find the number of neutrons in an atom, you would subtract
mass number from atomic number
atomic number from mass number
atomic number from electron number
isotope number from atomic number
Which statement is true about oxygen-16 and oxygen-18 ?
They do not have the same number of protons
their atoms have identical mass
they are isotopes of oxygen
they have the same mass number

carbon, iodine, tin
tin, copper, cesium
helium, iron, copper
iodine, carbon, argon
