A hypothetical element has two main isotopes with mass numbers of 93 and 96. If 66.00% of the isotopes have a mass number of 93 amu, what atomic weight should be listed on the periodic table for this element?

120,630,890

step-by-step explanation:

110+10=120,620+10=630,880+10=890

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates
