The atomic mass of an oxygen atom depends on which isotope of oxygen you are referring to. The AVERAGE atomic mass is approximately 15.9994
They don't contain the same number of particles because some particles are more dense than others making one atom and another atom the same mass but not have the same number of particles.
You can determine the approximate mass of an atom in atomic mass units by summing the number of protons and neutrons in the nucleus of the atom. The mass of a proton and neutron is approximately 1 atomic mass unit (amu), so the total mass of the atom would be the number of protons + number of neutrons in the nucleus.
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.
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) .
an oxygen and a hydrogen atom do not weight the same
The atomic mass of an oxygen atom depends on which isotope of oxygen you are referring to. The AVERAGE atomic mass is approximately 15.9994
An atom of oxygen has twice the weight of an atom of nitrogen since the atomic weight of nitrogen is around 14 amu (atomic mass units), while the atomic weight of oxygen is around 16 amu.
O = 16.00 a.m.u (atomic mass units) Mg = 24.31 a.m.u So, relatively speaking it is 1.519 times heavier
It isn't. Carbon is 6th on the Periodic Table and Oxygen is 8. Oxygen is the heavier element. mass of oxygen / mass of carbon 15.99g / 12.01g = 1.33 heavier than carbon
They don't contain the same number of particles because some particles are more dense than others making one atom and another atom the same mass but not have the same number of particles.
No, an oxygen atom does not have twice the mass of a sulfur atom. An oxygen atom has a mass of approximately 16 atomic mass units (amu), while a sulfur atom has a mass of approximately 32 amu. Therefore, a sulfur atom has twice the mass of an oxygen atom.
You can determine the approximate mass of an atom in atomic mass units by summing the number of protons and neutrons in the nucleus of the atom. The mass of a proton and neutron is approximately 1 atomic mass unit (amu), so the total mass of the atom would be the number of protons + number of neutrons in the nucleus.

Oxygen has an atomic number of 8. This also means that it has 8 protons in its nucleus.
Oxygen has 8 protons in the atom.
