What is Chemistry?
Chemistry is the study of everything if you can feel it taste it or smell its matter therefore everything.
electrons are?
Negative Charged
Proton is?
Positive charge!
Neutron is?
Neutral Charge!
Atoms consists of?
Protons Neutrons Electrons
Atoms “like” how many Electrons?
Atoms “like” 8 Electrons
Whats the atomic theory?
1) All matter is made up of tiny invisible particles called atoms.
2) Atoms are made up of smaller particles called sub-atomic particles.
3) The number and arrangement of the sub-atomic particles determines the size, shape and characteristics of the atom.
4) This arrangement also determines the type of compounds the atom can form.

3.Two of the basic parts are contained in the nucleus, the proton and neutron.
4.The third part circles the nucleus, the electron
5.Protons have a positive charge
6.Neutrons have no charge
7.Electrons have an negative charge.
What is a Ion?
An atom that has gained a positive or negative charge by losing or gaining an electron(s)
Whats an isotope?
An atom whose atomic mass varies from that of the common atomic mass of atoms of the same element. This is due to having a different number of neutrons than the most common form of that element.
