Explore Learning – Covalent Bonds Gizmo
Complete the Gizmo for each of the 10 molecules:
1) How many valence electrons does each atom have?
F-14 H-2 O-12 Cl-14 H2O-8 CO2-16 NH3-8 CH4-8 SiO2-16
2) Choose an electron from the outer shell of one atom and move it to the outer
shell of the other atom. Do this so that each atom achieves the stable octet. How many electrons
were shared for each compound?
F2-2 H2-2 O-4 N-6 Cl-2 H2O- N-6
3) Take a screen shot of each stable molecule (Hold down Shift – open apple – 4, then click and drag
over area). Show the Lewis dot structure of each molecule.
