I would say the centre. keep in mind that the electrons are about 1/2000th the mass of a proton or neutron which are equivalent - and at the centre of the atom.
The number of neutrons in an atom can affect the atomic mass of an atom.
An atom's mass does not change when it emits gamma radiation. Gamma radiation is a type of electromagnetic radiation with no mass or charge, so the total mass of the atom remains constant. The energy and momentum carried by the gamma radiation may cause the atom to recoil, but the mass of the atom itself does not change.
A face-centered cubic crystal has 12 nearest neighbors surrounding each atom.
The majority of an atom's mass is found in its nucleus, which is located at the center of the atom. The nucleus is composed of protons and neutrons, which are much more massive than the electrons that orbit the nucleus.
Essentially all of the atom's mass is in the nucleus. In the lightest atom, that of hydrogen, it's about 99.95 percent. In the heaviest naturally occurring atom, that of Uranium238, it's about 99.979 percent.
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.
