The atomic number will always be the same as

• Mass number and number of protons

• Number of neutrons and protons

• number of electrons and protons

• Number of electrons and neutrons

The periodic table is in order by the

• Mass number

• Neutron number

• Atomic number

• APE MAN Number

Which group of the periodic table is composed of inert (not reactive)  gases?

• alkali metals

• alkaline earth metals

• halogens

• noble gases

The atoms along the staircase are called 

• metals

• nonmetals

• metalloids

• noble gases

Elements in a ..................have similar chemical properties.  

• period

• group

• row

As you move down a group, atomic radius increases because - 

• you add more and more neutrons

• you add more and more protons

• you add more and more shells (energy levels)

• you add more atomic mass

If reaction starts with 20g of reactants it should produce 

• a total of 40g of products

• a total of 10g of products

• a total of 80 g of products

• a total of 20g of products
