Atoms Mindmap

1. They are made of smaller particles

2. Electrons are one type of particles found in atoms. they are negatively charged

3. Atoms are to small to see

4. They gain and lose electrons

   • sometimes an atom loses or gains one more electron and gives it a charge
   • charged atoms are known as ions
   • positive ions(+) are formed if atoms lose electrons
   • Negative ions(-) are formed if atoms gain electrons

5. Atoms can join together to make molecules

   • An element is a substance that only has one type of atom- so oxygen is a element
   • when one or more atoms are joined together you get molecules or compounds.
   • a compound is a substance made up of different types of atoms
   • atoms join together using chemical bonds
   • there are two main types of bonding between atoms-ionic and covalent
     • sometimes atoms can share a pair of electrons
       • this is a covalent bond
