The atomic mass of an atom is equal to the sum of numbers of what?
protons + electrons= atomic mass NUMBER, not the atomic mass.
The atomic mass refers to the number of what?
The atomic mass is approximately the sum of the number of protons and neutrons.
What is atomic number and atomic mass or weight?
Atomic number is the number of protons in an atom and atomic mass is the sum of the number of protons and neutrons.
What term best describes the sum of the number of protons and neutrons in an atom?
Atomic mass or mass number.
The formula mass of a molecule or an ion is?
The formula mass of a molecule or an ion is the sum of the atomic masses of all the atoms in the formula unit. This value is expressed in atomic mass units (amu) and is used to calculate the molar mass of the compound.
Which term describes the sum of the number of protons and neutrons in an atom?
when you could check in most of atoms that we have you will see that the sum of protons and electrons equals to or is called the atomic weight or atomic mass...that is if you add protons to electrons you have your atomic mass.
How are atomic mass and atomic number related?
The Atomic Mass number is the sum of the atomic number, the number of protons, and the number of neutrons in the nucleus of the atom.
What is the atomic mass of a atom?
The atomic mass of an atom is the total mass of protons, neutrons, and electrons in the atom, measured in atomic mass units (amu). It is approximately equal to the sum of the number of protons and neutrons in the atom's nucleus.
What number is the atomic mass equal to?
The atomic mass of an element is equal to the sum of the number of protons and neutrons in its nucleus. It is not directly related to the atomic number, which represents the number of protons in an atom.
What is the atomic mass number of an isotope that has an atomic number of 5 and 6 neutrons?
The Atomic Mass is, basically, the sum of the protons (the "atomic number"), and the number of neutrons.
What is the atomic mass number of an isotope that has an atomic number of 5 and has 6 neutrons?
The Atomic Mass is, basically, the sum of the protons (the "atomic number"), and the number of neutrons.
What is the atomic mass of an isotope that has an atomic number of 5 and includes 6 neutrons?
The Atomic Mass is, basically, the sum of the protons (the "atomic number"), and the number of neutrons.
