PERIODIC TABLE NOTES

PERIODIC TABLE NOTES. Periodic Table Facts. The periodic table lists all of the elements. Most of the elements occur naturally; however, several are man-made. The elements are arranged according to their atomic numbers (number of protons in the nucleus of the atom).

The Atom

The Atom. Smallest particle of an element that retains the properties of the element. The beginning. Democritus first suggested the existence of atoms in the 4 th century BC. John Dalton was the first to perform scientific experiments to test and correct his idea of the atom.

ATOMIC STRUCTURE

ATOMIC STRUCTURE. R.SANGEETHA VSMHS SCHOOL, CHENNAI. ATOMS AND SUBATOMIC PARTICLES. An atom is very small. Its mass is between 10-21 and 10-23g. A row of 107 atoms (10,000,000 atoms) extends only 1.0 mm. The subatomic particles are: 1.proton(+ve charge) 2.electron(neutral)

Atomic Number = number of protons Mass Number = number of protons + number of neutrons

Atomic Number = number of protons Mass Number = number of protons + number of neutrons Isotopes = atoms of the same element (having the same number of protons) having different numbers of neutrons. White, cloudy stuff (precipitate) forms
