That worked out perfectly! I understand where you're going now! THANK YOU SO MUCH!!!
Use the electron-dot symbols to show how the bonding (covalent or ionic) takes place. Use as many of each atom as needed for:
1. Carbon and Hydrogen
2.Silicon and Fluorine
try combinig the atoms in carbon and hydrogen; silicon and fluorine by using the perdioc table
CH4 and SiF4 are the formulae.
These are VERY hard to draw on the computer. I will do CH4 and you can do SiF4.
  H

H:C:H

  H
See how that looks. I may change it.
That's probably close enough for you to see how it's done.
