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.
A covalent bond forms between two nonmetals. It involves the sharing of electrons to gain a full valence shell. To determine if a bond is one or the other, look at the electronegativity of the atoms. If the electronegativity difference between two atoms is less than 0.4, the bond is nonpolar (< 5 % ionic character). If the electronegativity difference is between 0.4 and 1.6, the bond is polar covalent (from 5 % to 49 % ionic character).
