Atoms

Atoms

1. Sub-Atomic Atoms

   • Protons
     • Positively Charged
   • Electrons
     • Negatively Charged
   • Neutrons
     • Neutral Charge

2. Atomic Structure

   • 2 Goes in the first shell
     • 8 in 2nd 3rd 4th etc.

3. Ions

   • An atom which has lost or gained electrons
   • When a atom loses an electron, it becomes a posotive ion

4. Balacing Equations

   • H2+CL2=2HCL
   • The same amount of atoms need to be on each side.

5. Bonding

   • Covalent
     • Sharing electronic pairs between atoms
   • Ionic

6. Bonding

   • Covalent
     • A chemical bond that involves the sharing of electronic pairs between atoms.
   • Ionic
     • The bonding between a metal and a non metal that occurs when charged atoms loses one or more electron.

7. Questions of atoms

   • Why is sodium not very stable?
     • It on;y has 1 electron in its outer shell.
   • Why does Neon not bond with other elements?
     • Because it has a full outer shell and doews not react.

8. Bonding

   • Ionic
     • Bonding between a metal and a non metal that occurs when charged atoms attracts one electron.
   • Covalent
     • A chemical bond that involves the sharing of electronic pairs between atoms.

9. Questions about atoms.

   • Why is sodium not very stable?
     • It only has 1 electron in its outer shell.
   • Why does Neon not bond with other elements?
     • Because it has a full outer shell.
