From the atomic mass (mass number), one can deduce the number of ___ in each atom of an element. Define: the atomic number, atomic mass, and isotopes. Distinguish between the following terms: Atomic number and Mass number. How many neutrons does element x have if it's atomic number is...
How could Avogadro and his colleagues determine the number of atoms in a given substance, or any quantitative property of a single atom, when the technology to observe individual atoms was not invented until the twentieth century? Pioneering scientists of the atom, such as Avog...
The sum of an object’s mass is determined by the type, density, and the number of atoms in that object. No matter where you transfer the thing—whether into space or to another planet—it stays the same because the density and quantity of atoms remain constant. A measurement of an ...
atoms except the common form of hydrogen contain protons, neutrons and electrons. The atomic number of an element is equal to the number of protons in its nucleus. In a neutral atom, the number of protons equals the number of electrons in shells which is the energy level around the nucleus...

In nuclide (or isotope) tables the neutral atomic mass is not always given, but instead the mass excess (often, unfortunately, also called mass defect). We indicate this as δA and define it as the difference between the measured mass and the mass number of the particular atom: (3.4)δ...

1 pound equals 453.59237 grams. Stones are used to measure people’s weight. 1 stone is about 6.35 kilograms or exactly 14 pounds. Ounces are often used in cooking, especially with ingredients in small quantities. 1 ounce is 1⁄16 of a pound and about 28.35 grams. In Canada, many ...
Atomic mass unit (AMU) 1/12 the mass of a neutral atom of 12C, equal to 931.5 MeV. Atomic number (Z) Integer equal to the number of protons in a nucleus; the order of an element in the periodic table. Atomic weight or nuclear mass number (A) An integer equal to the sum of the...
