The atomic mass is determined by the contents of the [atomic] nucleus - the sum of the protons and neutrons; in this case the atomic mass {also called the atomic weight} is 31. A dalton is the mass of a hydrogen atom, or ion: that is, a proton.
Phosphorus is a non meta element. Atomic Mass of it is 31. Atomic number of it is 15.
The atomic mass number of phosphorus is 31.
Proton + Nuetron = Atomic Mass
The atomic mass of an atom is the combined mass of the protons and neutrons in the nucleus.
No, the atomic mass is the average mass of the atom and the atomic diameter is the average diameter of the atom
The number of neutrons in an atom can affect the atomic mass of an atom.
Atomic Mass represents the mass of atom. We use mass of protons and neutrons.
The atomic mass of an atom is the mass of 6.011 X 10^23 atoms of that element.
What do you mean? Atomic mass of an atom is the weighted average mass of all the naturally occurring isotopes of that element, measured in amu (=atomic mass unit). I do not know how do you want to call it, it is just atomic mass, average atomic mass, mass of an atom, atom's mass...
No, the atomic mass number is the number of protons plus the number of neutrons. The atomic mass of an atom is the total mass in a motionless atom.
Atomic mass is the mass of an atom in atomic mass units, and includes protons, neutrons, and electrons; and atomic number is the number of protons in the nucleus of the atom.
