An atom's mass is concentrated in its nucleus, which is located in the center of the atom. Protons and neutrons within the nucleus are responsible for its mass; the electrons, which are located outside of the nucleus, don't contribute to the mass of the atom.

Neutrons and they are found inside the nucleus.
What is true of an atoms nucleus?
It contains Protons and Neutron's.
Most calcium atoms have an atomic number of 20 and a mass number of 40 but some calcium atoms have a mass number of 48 What word could you use to describe these two kinds of calcium atoms?
Isotopes.
Is mass used as a method of counting atoms?
Most of the time yes. People and Scientists believe it is the easiest and most accurate way of measuring atoms.
Most atoms are composed of electrons protons and neutrons. Which particles are found in the nucleus of a gold atom?
Not just "most" atoms , but all atoms are composed of protons and neutrons, which are found in the nucleus, and electrons surrounding the nucleus in the electron cloud. And these atoms include gold.
What is the most of the mass of an atoms?

Most of the mass of the atom is where?
More then 99% of an atoms mass is in the nucleus.
What does most of the atoms mass come from?

Does most of the mass in atoms due to electrons?
no
What is atoms mass most made up off?
mass of protons + mass of neutrons

What is the formula mass of O5F2?
formula mass= atomic mass(found at the bottom of the element in question on the periodic table) multiplied by the quantity of atoms, repeat for other atoms and add together
What is most of the atoms mass?
The mass of an atom is concentrated in the nucleus (protons+neutrons).
If five atoms of hydrogen are reactants in a chemical reaction then how many atoms of hydrogen will be found in the products of that reaction?
Mass is conserved in a chemical reaction, so the mass before must equal the mass after. If you have five atoms before, you must have five atoms after.
What is true of an atoms's nucleus?
negatively charged and takes up most of the atoms space Takes up most of the atoms mass and is negatively charged
Is every thing on earth made of atoms?
Atoms exist throughout the universe. the most common atom in the universe is hydrogen. Helium is the second most common found in the universe, and oxygen is the third.
