The Atomic Mass number or nucleon number. The atomic mass number is written in superscript on the left of the elements symbol.
What else can I help you with?
The sum of the numberof protons and nuetrons in the nucleus of an atom?
The sum of the number of the protons and neutrons in the nucleus of an atom is called as atomic mass.
What would you find in an atom?

Is the very small dense center of an atom?
Nucleus
What is the sum of the number of protons and the number nuetrons in an atom?
mass number
Why is the helium atom's nucleus postively charged?
Anything that is positively charged means that it has an extra number of protons. 1. PROTONS = Positive 2. NUETRONS = Neutral 3. ELECTRONS = Negative The Helium atom could have 6 protons, 5 nuetrons, and 5 electrons. The extra proton would make the atom Positive.

The nucleus
What is the total the number of protons and nuetrons in the nucleus of an atom?
Z, also known as the mass number, describes the total number of protons and neutrons in a nucleus.
How are protons and nuetrons a like?
They are both found in the nucleus of an atom.
What parts of an atom are found inside the nucleus?
protons and neutrons
Central part of atom that containes protons and nuetrons?
The part of the atom that contains neutrons and protons is called the nucleus.
What does the atomic mass tell us?
it tells us that the number is equal to the number of protons plus the number of nuetrons in the nucleus of an atom
What would you find in an atom?
protons and nuetrons in the nucleus and electrons in a lcoud sorrounding it
