Is mass used as a method of counting atoms?
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.
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. Calcium atoms with a mass number of 40 represent the most common isotope, while those with a mass number of 48 are a less common, but still natural, isotopic form of calcium.
What has no charge but add mass to the atoms?
Neutrons and they are found inside the nucleus.
How do you calculate the molecular mass of a compound?
To calculate the molecular mass of a compound, you add up the atomic masses of all the atoms in the compound. This can be found on the periodic table.
What is the mass of x atoms of sulfur?
208
What is the most of the mass of an atoms?
The nucleus.
What subtomic particle account for most all of an atoms mass?
Protons and neutrons, which are found in an atom's nucleus, account for most of an atom's mass. Electrons, which orbit the nucleus, have much less mass compared to protons and neutrons.
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?
the nucleus
Where is most of an atoms mass?
Inside the nucleus.
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 most of the atoms mass?
The mass of an atom is concentrated in the nucleus (protons+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 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.
