bonding

bonding

1. Atomic structure

   • atomic mass-number of protons and neutrons
     • atomic number - number of protons in the atom
     • electrons and protons have some number
       • proton- postive, found in nucleus
         • neutron -neutral, found in the nucleus
           • electron - negative,electrons shells

2. ionic bonding

   • this happens between a metal and a non metal
     • they are strong because they have strong attractions between oppositely charged ions
       • if a atom loses an electron is has a positive charged
         • if an atom gains an electrons it has a negative charge

3. giant ionic bonding

   • they make large structures called lattice
     • they have a very hgih melting point because they have a strong ionic bonds
   • they can conduct electricity when they are dissolved in water or melted

4. metallic bonding

   • metals generally like to lose electrons to form positive ions
     • these electrons being lost are all donated into the sea of eletrons

5. simple covalent

   • covalent bonds happen between a non metal and a non metal , electrons are shared
