Started Chemistry - The Atom.

An Atom is the the smallest part of an element which still maintains the properties of that element.


We learned also that:

• Protons are found in the nucleus, have a positive charge and a mass of 1 atomic  mass unit.
• Neutrons are found in the nucleus, have no charge and a mass of 1 atomic mass unit.
• Electrons are found orbiting the nucleus, have a negative charge and a mass 1/1840 atomic mass units.

HW - Draw Bohr Models of Boron, Sulfur and Argon atoms.
