Worksheet PrintWorksheet 1. If you know the atomic number and the atomic mass of an atom then you should be able to figure out... the number of protons the number of neutrons the name of the element all of these 2. Nitrogen has an atomic number of 7 and it has 7 neutrons. What is...
Atomic number: number of protons in the nucleus of the atom. It defines the chemical properties of the atom. Atomic mass: mass of one mole of atoms, in grams, averaged over all stable isotopes. The atom mass of a pure isotope is equal to the number of protons and neutrons. The unit ...
Atomic Number • Hydrogen has one proton in the nucleus, and 1 electron around its nucleus. • Oxygen has eight protons in the nucleus, and eight electrons around its nucleus. Mass Number • Mass number is made up of the total number of protons and neutrons in the nucleus of an ...
Use these models to explain the difference between atomic weight and number. Make a drawing showing how nuclear fission happens. Label all details. Draw a second picture showing how a chain reaction could be started. Also show how it could be stopped. Show what is meant by a 'critical mass...

The changing models of atomic structure over time and the use of evidence to accept or reject particular models. Atomic structure in terms of the numbers of protons, neutrons and electrons for atoms and ions, given the atomic number, mass number and any ionic charge....
Atomic number of Cr is 24. Atomic Mass (amu) Atomic Mass (amu) In nature, most elements occur as mixture of one or two isotopes. Each isotope has a fixed mass and natural percent abundance. Consider three isotopes of Hydrogen Hydrogen 1 (99.985%) Hydrogen 2 and 3 present in trace amoun...
