What does the atomic mass of an atom represent?
the mass of an atom of a chemical element expressed in atomic mass units. It is approximately equivalent to the number of protons and neutrons in the atom (the mass number) or to the average number allowing for the relative abundances of different isotopes.
What does atomic mass represent of an element represent?
Atomic Mass represents the mass of atom. We use mass of protons and neutrons.
Is atomic number the same as mass number?
Atomic number is the number of protons in the atom; atom mass is the total mass of the atom (usually neglecting the mass of the electrons because they have so little).
Why atomic mass is different from the mass numbers?
atomic mass is the number of protons in an atom mass number is the number of protons plus neutrons in an atom
What does the mass number in helium represent?
The mass number in Helium represents how much space a single helium atom takes up (not including electrons, because electrons can be bonded, and my come and go)
What does the Mass number in chemistry represent?
the atomic mass incdicated the amount of protons and neutrons of the atom
Why does not an atom of an element represent the actual mass of its atom?
The atomic mass of an element is measured not in the mass of the atom, but in the number of grams per mole.

What does the number above the symbol represent?
The atomic number.
What does atomic mass represent of an element represent?
Atomic Mass represents the mass of atom. We use mass of protons and neutrons.
What do the numbers on mendeleev's periodic table represent?
The Atomic number which is the number of protons in an atom's nucleus.
What equals the number of neutrons plus the number of protons in an atom?
The mass number is a whole number that is equal to the sum of protons and neutrons in an atom. Mass number is represented by the letter (A) orA= Z + N (Z) represent the atomic number or the number of protons in the nucleus.
What do you get when you change the mass number of an atom?
You can't change the mass number of an atom because the mass number is the number of protons which is the atom's atomic number I hope this helped :)
What is the mass number of a atom?
the mass number is number of protons in an atom, plus the number of neutrons.
What is the number of neutrons in an atom affects the atomic what?
The number of neutrons in an atom can affect the atomic mass of an atom.
