the nucleus
All protons have the same mass regardless of where they come from. It should be noted, however, that most of the mass in atoms comes from the forces holding the atom together.
The nucleus.
More then 99% of an atoms mass is in the nucleus.

mass of protons + mass of neutrons
The mass of an atom is concentrated in the nucleus (protons+neutrons).
Mass is not used as a method of counting atoms directly. Instead, the atomic mass unit (amu) is used to measure the mass of individual atoms relative to the mass of a carbon-12 atom. The mole is the unit used to count atoms, with 1 mole containing Avogadro's number of atoms.
negatively charged and takes up most of the atoms space Takes up most of the atoms mass and is negatively charged
Most of the mass of glucose comes from carbon atoms, which are incorporated into the glucose molecule during photosynthesis. Carbon dioxide is taken in from the air during photosynthesis and converted into glucose, providing the majority of its mass.
It contains Protons and Neutron's.
The mass numbers are given on the periodic table.
