REVIEW: Subatomic Particles and Nuclear Reactions

RECALL:

• Atom, which is the basic unit of matter is composed of protons, neutrons, and electrons.

• Protons are responsible in setting the identity of an element (e.g. 1 proton = hydrogen, 2 protons = helium, 3 = lithium and so forth...)

• Neutrons act as the "glue" or binding force that hold the nucleus together.

• Electrons are mainly responsible for chemical bonding (next lesson)

ATOMS CAN UNDERGO CHANGES THROUGH VARIOUS MEANS. THIS TIME, OUR FOCUS IS ON:

• Nuclear Changes - analyzed with the help of nuclear equations

Let us have a quick review first of the subatomic particles before reviewing about nuclear equations.
