In science the basic unit is the atom which is composed of neutrons, protons, and electrons. Electrons are generally considered to small to count as part of the mass. Atomic Mass is the sum of neutrons and protons. For example: Oxygen has 6 protons and, in its natural state, 6 neutrons. This means that its atomic mass is 12.

What does the atomic mass equals the number of?
An isotope's mass number is the sum of the protons and neutrons in each atomic nucleus of the isotope.
Atomic mass equals the number of what?
The atomic mass NUMBER equals the number of protons and neutrons in an atom. DO NOT confuse this with the mass of an atom.
What is the atomic mass-?
The atomic mass is the mass of a molecule, atomic particle or sub-atomic particle.
What is the atomic mass of colbat?
Cobalt is an atomic mass of 58.93 atomic mass units
The equation of atomic mass?
== The equation of atomic mass is protons+nuetrons== atomic mass. ===
Atomic mass equals 140.12?

What does the atomic mass equals the number of?
An isotope's mass number is the sum of the protons and neutrons in each atomic nucleus of the isotope.
Which element has an atomic mass equals 16?
umm oxygen
Why is the atomic mass scale also called the relative atomic mass scale?
All atomic masses are determined by comparing them to the mass of an atom of carbon12. One atomic mass unit equals one twelfth the mass of an atom of carbon12. That's why its called relativeatomic mass.
Mass number - atomic number equals?
Mass number minus the atomic number equals the number of neutrons. Mass number is the number of particles in an atom that have significant mass. Electrons are assigned a value of 0 since the mass is so much smaller than protons and neutrons. Protons and neutrons are similar in mass and are assigned mass number of 1. The formula for calculating atomic mass atomic mass = # protons + # neutrons.
One atomic mass unit equals 931 MeV?
The atomic mass unit is equal to 931,494 061(21) eV/c2.
What is the total mass of an atom of nitrogen known as?
It is known as the atomic mass of nitrogen. It equals 14.00674
What is the atomic mass of a atom that has 6 neutron 6 protons and 6 electron?
Number of protons = atomic number = 6 atomic units Number of protons + neutrons = mass number = 13 atomic units
What The atomic mass of an atom equals the sum of the masses of the?
Protons and neutrons.
What is hydrogen's number of neutrons equals mass number - atomic number equals?
A hydrogen atom has one proton, one electron and '''zero''' neutrons. Rephrased, the question is: Hydrogen's number of neutrons equals mass number - atomic number.
Atomic mass equals the number of what?
The atomic mass NUMBER equals the number of protons and neutrons in an atom. DO NOT confuse this with the mass of an atom.
Does water have a mass of 18 grams?
