Question

State everything you know about the following atoms. Do NOT assume that they are balanced or neutral.
Atomic number = 98
Mass number = 101

Answer 1

Everything I know??? That might be volumes. It might also be minuscule. At any rate, what the problem is getting at is for you to look at the periodic table and identify element #98. I am having trouble with the mass number of 101 (I might believe number of neutrons = 101 which would make the mass number 199). Here is a site that will give you more information.

Answer 2

I put down that there are 98 protons, 3 neutrons

Answer 3

That would be right for a mass number of 101 and an atomic number of 98. Do you know why that is highly unlikely? Mostly because the repulsive force between 98 protons is enormous; more neutrons must be in the mix to help hold the nucleus together.
