What is the approximate mass of an oxygen atom in atomic mass units?
16 amu
What is the approximate mass of a neon-11 atom?
The approximate mass is 11. Technically you could express this in units of daltons as 11 Da (Daltons previously called amu, atomic mass unit, or as 11 (the dimensionless, relative atomic mass which chemists simply call atomic weight) .
The mass of an atom usually expressed in atomic mass units is its?
Atomic mass
How do scientists determine the number of neutrons and isotopes in an atom?
Atomic mass minus atomic number. This is rather simplified but the atomic mass of an element is the total of all the protons, neutrons, and electrons in an atom. Each proton and neutron has an atomic mass of approximately 1 AMU (atomic mass units) while an electron has an atomic mass of about 0.0005 AMU. So, you don't need to worry about the electrons. The atomic number of an element is simply the number of protons in the atom. So, atomic mass (number of protons and neutrons) minus atomic number (number of protons) equals number of neutrons in an atom.
What determine the mass of a atom?
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 is the approximate mass of an oxygen atom in atomic mass units?
16 amu
How do you determine the atom the atomic mass of an atom?
Proton + Nuetron = Atomic Mass

What does the number of neutrons determine?
they determine the atomic mass of the atom
The mass of an atom usually expressed in atomic mass units is its?
Atomic mass
How do you determine the numbers of the three types of particles in each atom?
In an atom, no. of protons = no. of electrons=atomic no. no. of neutrons=atomic mass-atomic no.
The approximate mass of the hydrogen atom?
The conventional standard atomic weight of the hydrogen atom is 1,008 amu.

How can you determine the number of electrons in a atom?
The atomic number
What determine the atomic number of atom?
The number of protons
What do we do to determine the number of neutrons in a atom?
atomic number
The number of these will determine it's atomic number?
The atomic number of any atom is determined by the number of protons in the nucleus of the atom.
