How do you get atomic mass?
Atomic mass is found by adding together the individual masses of the numbers of protons, neutrons, and electrons in the atom.--> Atomic Mass = protons + neutrons
The atomic mass equals what?
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 parts of an atom are equal to each other?
It depends on what you mean by what parts are equal. Protons and electrons both have the same magnitude of charge with opposite signs and electrons are much less massive than protons. Protons and neutrons are approximately equal in mass but protons have a charge of +e Coulombs while neutrons have a charge of 0. Atoms can often exist with unequal numbers of protons and electrons. Such atoms are called ions and have a negative charge if they have more electrons than protons and positive charge if they have more protons than electrons.
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.

Neutral atom with 53 protons in its nucleus would have how many electrons orbiting the nucleus?
For a standard atom, the number of protons, electrons, and neutrons is the same. For example: 2 Protons - 2 Neutrons - 2 Electrons Helium 3 Protons - 3 Neutrons - 3 Electrons Lithium 4 Protons - 4 Neutrons - 4 Electrons Beryllium So... 53 Protons - 53 Neutrons - 53 Electrons Iodine
Protons neutrons electrons for lithium?

How many protons neutrons electrons are found in the beryllium atom?
All beryllium atoms have 4 protons and 4 electrons. The number of neutrons is characteristic of a particular isotope, not of beryllium as a whole, and may be determined by subtracting 4, the number of protons, from the mass number of the isotope.
