Two isotopes of carbon are Carbon-12 and Carbon-14.  Atoms of C-14 will have:

• the same number of protons and neutrons as atoms of C-12

• the same number of protons but 2 more neutrons than atoms of C-12

• 2 more protons but the same number of neutrons as atoms of C-12

• 1 more proton and 1 more neutron than atoms of C-12

Select the TWO that are isotopes.

• Carbon-11 & Boron-11

• Boron-11 & Boron-12

• Sodium-23 & Vanadium-51

• Carbon-12 & Carbon-12

Isotopes are atoms __

• that are different elements that have the same mass

• that are the same element but have different masses

• that are different elements that have different masses

• that have different numbers of protons but the same number of neutrons

What is the correct Isotope Name for an atom that has 9 protons and 10 neutrons?

• Fluorine-19

• Fluorine-10

• Neon-19

• Fluorine-18.998

• Neon-10
