What is the approximate mass of an oxygen atom in atomic mass units?
The approximate mass of an oxygen atom in atomic mass units is 16. Oxygen has an atomic number of 8, which means that its atomic mass is approximately 16 atomic mass units.
Does an atom of aluminum and an atom of gallium have the same atomic mass?
No, an atom of aluminum and an atom of gallium do not have the same atomic mass. Aluminum has an atomic mass of approximately 26.98 atomic mass units, while gallium has an atomic mass of approximately 69.72 atomic mass units.
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 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.
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 is the weight of one hydrogen atom?
The atomic weight of hydrogen is 1,007 94 ± 0,000 07 atomic units of mass.
What is the Mass number of a bromine atom?
Bromine has an approximate atomic mass of 79.904.
What is atomic mass of an atom?
The atomic mass of an atom is the sum of the number of protons and neutrons in the nucleus. It is generally expressed in atomic mass units (amu). The atomic mass is important for determining the overall mass of an atom and for calculating molar masses in chemical reactions.
