Each element on the periodic table has two important numbers, the atomic number and the mass number. The atomic number is equal to the number of protons and the mass number is equal to the mass of one atom in atomic mass units (amu). ...

isotope, one of two or more species of atoms of a chemical element with the same atomic number and position in the periodic table and nearly identical chemical behaviour but with different atomic masses and physical properties. Every chemical element has one or more isotopes. An atom is first ...
(zg, zgs)The prefix "zepto" means 1/1,000,000,000,000,000,000,000= 1e-21, so 1,000,000,000,000,000,000,000zg = 1e+21 zg = 1 g. 1000 zg = 1 attogram. 1 zg = 1e-24 kg. For comparison, one atom of platinum weighs approximately 3.02e-22 g so 3 atoms of platinum we...
This equation gives only ratios of masses; it is therefore necessary to designate the mass of some one body as the standard mass to which the masses of all other bodies can be compared. The body that has been chosen for this purpose is a cylinder of platinum-iridium alloy. It is known ...
What is the weight of one mole? If the mass of the C atom is 2.0 times 10^{23} kg. What is the density of carbon atoms? What two sets of units can be used to describe density? Why are they interchangeable? Using ...
