elecrtonic structure

elecrtonic structure

1. Atoms with full outer shells are more stable

   • Atoms without full outer shells want to get a full outer shell
     • so they must either gain or loss an electron to be more stable
       • e.g flourine can gain 1 electron to complete an outer shell

2. a change in electrons gives an element a charge

   • because there is more electrons than protons
     • e.g flourine would gain a 1+ charge

3. ion

   • atom with a charge

4. ionic bond=

   • electrostatic attraction between positive and negative charge
   • strong bonds hold the structure together
