  • C1.1
    • Atoms
      • Atoms have tiny nucleus surrounded by electrons
      • Atoms are represented by a chemical symbol e.g O for Oxygen
    • Elements
      • Each element is made up of one type of atom
      • Elements in the periodic table are arranged in columns called groups
      • When elements react their atoms connects with other atoms of other elements
      • Compounds are formed when two are more elements are combined together
    • Atomic Structures
      • Protons have a positive charge
      • The nucleus which is at the centre of the atoms contains two type of particles, called protons and neutrons
      • Neutrons have no charge
      • Electrons have a negative charge
      • The Mass number is the total number of particles in the nucleus of an atom. So it is the number of protons + number of neutrons
      • Elements are arranged in order of their atomic number
    • Electrons in Atoms
      • Elements in the same group in the periodic table have the same number of electrons
      • Each electron is a atmos energy level
      • The lower the number on the outer shell, the more reactive it is.
    • Forming bonds
      • When different elements combine they form a compund
      • When a metal reacts with a non metal ions are formed
      • Metal atoms lose one or more electrons to form a positively  charged ions
      • Non- Metals atoms gain electrons to form a negatively charged ion.
      • When non- metals combine their atoms, share electrons to form a covalent bond and molecules are formed
      • The chemical formula of a moleule tells us the number of atoms that have bonded together in the molecule
  • Atomic Structures
    • Protons have a positive charge
    • The nucleus which is at the centre of the atoms contains two type of particles, called protons and neutrons
    • Neutrons have no charge
    • Electrons have a negative charge
    • The Mass number is the total number of particles in the nucleus of an atom. So it is the number of protons + number of neutrons
    • Elements are arranged in order of their atomic number
  • Electrons in Atoms
    • Elements in the same group in the periodic table have the same number of electrons
    • Each electron is a atmos energy level
    • The lower the number on the outer shell, the more reactive it is.

I will be doing a whole series of these mind maps.

Let me know if you want any other revision notes
