Atoms consist of protons, which carry a positive electrical charge; electrons, which carry a negative charge; and neutrons, which carry no charge. Thus in an ordinary, electrically neutral atom, the number of protons and the number of electrons is equal. ...
Half-life - The time taken for half the radioactive nuclei in a sample to decay.Isotope - Atoms of the same element with different numbers of neutrons.Ionization - The process of adding or removing electrons from an atom or molecule, creating ions.Coulomb's Law - The force between two ...
Use the Periodic Table and mass number to evaluate atomic structure. The atomic number equals protons. The mass number minus the atomic number equals neutrons. In neutral atoms, electrons equal protons. In unbalanced atoms, find electrons by adding the o

mass and can occupy a volume. With this definition of matter, one example of matter is chair since it has a mass and occupies a volume. One characteristic of a matter is that it is made up of atoms and subatomic particles. The subatomic particles are the protons, neutrons, and electrons...
Since an atom contains equal number of protons and electrons, it has no overall charge: the positive charges on all the protons are exactly balanced by the negative charges on all the electrons. But sometimes an atom can gain or lose an electron to become what's called an ion. If it ...
Atoms, the basic building blocks of matter, are made of three basic components: protons, neutrons and electrons. The protons and neutrons cluster together to form the nucleus, the central part of the atom, and the electrons orbit about the nucleus. Protons and electrons both carry an ...
