This depends on whether you are referring to the atom as a whole or if you mean what gives the most mass in the nucleus (which is where the most weight is in an atom). The weight of the nucleus or the center of the atom is the number of neutrons plus the number of protons, assuming we calculate by the relative mass of both particles, which is 1 Atomic Mass unit (amu).
Atomic mass = # neutrons + # protons
The neutron has a relative mass of 1 amu, yet its actual mass is about 1.675 x 10-24 grams.
The proton has a relative mass of 1 amu, yet its actual mass is about 1.673 x 10-24 grams.
The electron is not calculated in the atomic mass (not part of the nucleus), as it has a relative mass of 0 atomic mass units (amu), although its actual mass is actually about 9.110 x 10-28 grams.
The particle that weighs the most in an atom is the neutron, although the atomic mass as stated above is the sum of how many neutrons and protons are located in the nucleus.
The nucleus of an atom is the densest part of an atom. It contains the protons and neutrons of an atom.
The nucleus is the positively central part of an atom. It contains protons and neutrons, which are responsible for most of an atom's mass.
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 is the part of an atom that contains practically all its mass. In the nucleus, you can find the proton and neutron. The number of electrons, which move about the nucleus, is equal to the number of protons.
Protons and neutrons, the particles that make up atomic nuclei, are the ones responsible for almost all of the mass of an atom. As the electron has less than 1/1800th the mass of a proton, a whole flock of electrons won't significantly change the mass of an atom. We look to the protons and neutrons (called nucleons when they are being considered as components of an atomic nucleus) to contribute to the mass of an atom, and they will be considered when we derive the atom weight of an element.

The nucleus of an atom is the densest part of an atom. It contains the protons and neutrons of an atom.
The nucleus contains the mass.

the nucleus
The electron is the smallest subatomic particle in an atom and has almost no mass compared to the proton and neutron.
The electron.
The nucleus of an atom is the central core that contains protons and neutrons. Protons have a positive charge, while neutrons have no charge. The nucleus is held together by the strong nuclear force.
The nucleus contains the majority of the mass in an atom. The nucleus contains the protons and neutrons, which each have a relative mass of 1 amu. The electrons surround the nucleus and have a relative mass of 0 amu.
lithium
The nucleus of an atom is the heaviest part and contains most of the atom's mass. It is made up of protons and neutrons. Electrons, which orbit the nucleus, have much less mass compared to protons and neutrons.
The Nucleus contains Protons and Neutrons which comprise practically all the atom's mass.
