Isotopes

Match it! Select the correct answer from the pull down...Good luck!

The reason isotopes have the same atomic number but different mass numbers is they have different numbers of:

What is the atomic mass number of an oxygen (atomic number 8) isotope that has 10 neutrons?

Every atom of an given element has the same number of what two subatomic particles?

Atoms of the same element that have different numbers numbers of neutrons in the nucleus AND different mass numbers are called:

Oxygen atoms have 8 protons in their nucleus, giving them an atomic number of:

All isotopes of a given element have the same:

Every atom of a given element does NOT have the same number of what subatomic particle?

What is the atomic mass number of an oxygen (atomic number 8) isotope that has 9 neutrons?
