11 reviews of Favorite / Famous Doughnuts This spot os chill. I used to come over here, super late at night and buy cigarettes here. Their donuts are descent, and the people behind the counter are super cool. I don't know, it was the kick it spot.
In this simulation, students investigate both ionic and covalent bonding. Students will have the opportunity to interact with many possible combinations of atoms and will be tasked with determining the type of bond and the number of atom needed to form each.
To figure this out, you calculate the delta EN (difference in the electronegativities) and then just identify it. If the delta EN = 0 - 0.4, then the bond is non-polar covalent. If the delta EN = 0.4 - 1.9, then the bond is polar covalent. If the delta EN = 1.9 or above, then the bond is definitely ionic. Another theory is the Valence Shell Electron Pair Repulsion (VSEPR) .
