Types of Particles
• Protons: positively charged particles (1 atomic mass unit)
• Neutrons: neutrally charged particles (without charge/ 1 amu)
• Electrons: negatively charged particles (too small to include in
mass)
Symbols and location:
• (p+) and (n0) are found in the nucleus of the atom
• (e-) swarm about the nucleus in a cloud
• The number of protons = the number of electrons
• p+ = e-
Draw and lable this:
Number of protons;
Identifies element
Number of protons +
neutrons;
Does not ID the element
Atomic Charge
• When the number of protons and electrons are equal the
atom has no charge
• (p+) = (e-) the atom has no charge
• A charge indicates the gain or loss of electrons.
• Add an (e-) = a negative charge
• Take away an (e-) = a positive charge
