All atoms share the same basic structure...
Protons (positive charge +)
Neutrons (Neutral charge )
Electrons (Negative charge -)
These smaller inner particles are located within the nucleus
5
All atoms share the same basic structure...
Multiple scientists spent years to describe or model what the atom looked like
John Dalton was the first to say that all matter is composed of tiny particles called atoms & could not be divided any further
JJ Thompson & Rutherford discover the inner particles (i.e. electron, neutron, & proton)

Elements
Elements differ in the # of Protons
The atomic # of an element is defined by the # of protons
The # of electrons of each element determines the properties of that element (i.e. gas, liquid, solid, metal. nonmetal)
Compounds involve two different elements bonded together (Ex: H2O & CO2)

Atomic Love Connection?
A molecule is 2 or more atoms held together by covalent bonds. Almost all of the substances that makeup organisms (i.e. ATP, DNA, RNA, Water) are molecules.
