#1 Predict the electron and molecule geometry with 6 bonding domains and a single lone pair. Bad answers will get reported. Correct answers get 50 points and brainliest!

According to VSEPR theory the molecule with six binding domains and single lone pair will have the pentagonal bipyramidal geometry. As it is known that six binding domains means six bonds and a single lone pair means one pyramidal bond, so that it does not repel bonds to a higher extent. Hence, total of seven bonds are required which is provided by the pentagonal bipyramidal geometry. The number of electrons of the molecule will be fourteen 2 from each of the 6 binding domains that makes up to 12 and 2 from the lone pair.

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6
