Don’t mind the incorrect part & da last part for model 3

The second model.

Explanation:

In a Bohr Model, you have your nucleus in the middle, in #1, it's the relatively large black circle, and in #2, it is the large grey dot with the number of protons & neutrons in the center. Now the first ring of a Bohr Model can hold a maximum of 2 electrons. The second ring of a Bohr Model can hold a maximum of 8 electrons. If the element has more than 10 electrons, there will be a third ring (as is shown on your worksheet), and the third ring can hold a whopping 18 electrons!

(Continued from my last answer)

In question #3, the first model follows the orbital rules, as we have 2 electrons on the first ring, 8 electrons on the second ring, and 6 electrons on the third ring. On the other hand, the second model does not follow the orbital rules, as we have 2 electrons on the first ring, only 4 electrons on the second ring, and 10 on the third ring. The mistake here is found on the second ring, as we must hold the max amount of electrons on a ring before moving to the next ring. If the second model were to be correct, it would be shown as 2 electrons on the first ring, 8 electrons on the second ring, and 6 electrons on the third ring.

it is important to conserve water because there is very limited amount of freshwater here on earth and if we are not smart about how we use it we will only be runnning out of our supply faster than neccessarry.

they vary. it used to be meat, grain, bread, candy, beverages, donuts, and fruits/vegetables. now they added exercise in.
