Consider a molecule of CO2.
A.) Are the bonds polar or nonpolar?
B.) Is the molecule polar or nonpolar?
Explain your reasoning for each.
B.) The molecule is nonpolar because the dipole moments cancel each other out.
What 2 major conclusions did Ernest Rutherford make from the results of his famous Gold Foil Experiment? For each, explain the specific observation that led to it.
1.) Atoms are mostly empty space (because most of the alpha particles went straight through the gold foil).
2.) Atoms have a small, dense, positively charged nucleus (because some of the alpha particles bounced back after hitting the nucleus).
