CHEMISTRY

1. In the nucleus of an Atom

   • Protons: Positively Charged
   • Neurons: No charged
   • Electrons: Negatively charged

2. Atomic Number: An atomic number is the number that tells us how many protons and element has and there for the number of neutrons and electrons it has.

3. Anions (Negative Charge): Ions which have gained electrons so they have more negative charges than positive charges

4. Covanlent= Two non-metals

   • Ionic= Non-metal + Metal

5. Ions are atoms that have gained or lost electrons.
