kindly restate your question. it doesnt makes sense
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.
The nucleus of an atom represents most of an atom's mass.
The Hydrogen atom. Beware, Hydrogen has an atomic mass based on one proton, as it doesn't have a neutron. So Helium has a mass of four times Hydrogen.
Adding a neutron increases the atom's mass by about 1 AMU assuming it remains stable.
Mass of an atom is determined by the no. of protons+ no. of neutrons in the atom.
99.9% of the mass of an atom is located in the nucleus

Yes, the mass of an iron atom is different from the mass of a copper atom. The mass of an iron atom is approximately 56 atomic mass units, while the mass of a copper atom is approximately 63.5 atomic mass units. Therefore, there is a difference of about 7.5 atomic mass units between the two.
The atomic mass of an atom is the combined mass of the protons and neutrons in the nucleus.
There exists no mass less atoms. Every atom has a mass.
The mass of a carbon atom is approximately 12 atomic mass units.
The mass of a calcium atom is around 40 atomic mass units (u), while the mass of a helium atom is around 4 atomic mass units (u). Therefore, the mass of a calcium atom is 10 times greater than the mass of a helium atom.
