Question 1

What are isotopes?

Answer 1

Atoms with the same number of protons but a different number of neutrons (and therefore a different mass).

Question 2

What do isotopes have?

Answer 2

Identical chemical properties since is the # of electrons that determines chemical reactivity, but they will have slightly different physical properties due to the difference in mass.

Question 3

What are some isotopes? What these isotopes called?

Answer 3

Radioactive and emit radiation (alpha, betta. and gamma); these are called radioisotopes.

Question 4

What are all elements beyond atomic number 88?

Answer 4

Radioactive

Question 5

What does the existence of isotopes contribute to?

Answer 5

The average atomic masses of elements on the periodic table.
