Question

all isotopes of the SAME atom will always have the same ___________ or ______ count.please help have a test tomorrow, and this is the study guide

Answer 1

Isotope means that the same element can have a different mass number.
What is the formula for mass number that you know?
What do you know about proton and mass number?

Answer 2

it has the same amount of protons and electons? and the mass #'s formula is protons+neutrons= mass number?

Answer 3

Yes, proton=atomic number
So it will have same amount of proton.
Since the same atom will always have the same atomic number. The proton will always be the same and so is electron because electron charge+proton charge=0
You were right.

Answer 4

Isotopes have same protons and electrons.
