• Atom: the smallest possible unit of an element that maintains the properties of that element
• the basic structural components of a typical atom are proton, neutron, and electrons.
• proton- positive charge
• neutron- neutral charge
• electron- negative charge
• nucleus- positive charge
• - the atoms of one element differ from those of another element in the number of protons. This number is called the element's atomic number.
• - if atoms are neutral, then they have the same number of protons and neutrons
• - an element is a form of matter made up of one type of atom. The atoms of an element are basically alike, though the number of neutrons may vary.
• elements can be represented by chemical symbol
