Atoms,Isotopes, Ions, Periodic Table

Atoms: Atoms consist of three basic particles: protons, electrons, and neutrons
Isotopes: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
An ion is an atom or molecule that has a different number of electrons than protons, so it has a charge.
Periodic Table: a table of the chemical elements arranged in order of atomic number, usually in rows, so that elements with similar atomic structure (and hence similar chemical properties) appear in vertical columns.
1. The number of the periodic table is the number of atoms of an element.
An atom becomes charged when the number of protons does not equal the number of electrons. For example, if an element has six protons but only five electrons, the net charge of the element is +1. Conversely, if an element has six protons but seven electrons, then the net charge of the element is -1.
When you write an element, you write the elements name, atomic mass, and number of protons (atomic number)
