what do you call an atom of an element that contains the same number of protons as other atoms of that element but a different number of neutrons
Isotope
What is the atomic number of an element
The atomic number is the number of protons in an atom’s nucleus
the sum of the numbers of protons and neutrons in the nucleus is called the
mass number
how much does a proton or a neutron weigh
1 Atomic mass unit
what is an isotope
an atom of an element that contains the same number of protons as other atoms of that element but a different number of neutrons
what is the difference between the atomic number and the mass number
atomic number is the number of protons
mass number is the number of protons and neutrons
