Answer:
Explanation:
The atom X has 1 1 protons (atomic number) and thus would have 11 electrons. This means the atom X would have 1 valence electron in it's outermost shell. While the atom Y has 17 protons (atomic number) and thus would have 17 electrons. This means the atom Y would have 7 electrons in it's outermost shell.
The type of bond this atoms (X and Y) would form is an Ionic (or electrovalent) bond. <u>This bond/combination involves the transfer of electron(s) and a molecule is not formed</u> as seen in the image below.

Answer:
<h2>
The answer is $6.52.</h2>
Explanation:
Firstly, let's check out the given:
1. Sports Utility Vehicle's (Original SUV) avg gas mileage - 17.5 miles per gallon (mpg)
2. SUV's (Hybrid SUV) avg gas mileage - 21.5 miles per gallon (mpg)
3. Gas price - $2.59 per gallon
What is asked? How much would you save driving 237 miles in the hybrid SUV compared to the original SUV?
Next, you have to know how much gallons each car consumes upon driving 237 miles. You can do division in this step.
1. Original SUV = 237 miles ÷ 
= 13.54 gallons
2. Hybrid SUV = 237 miles ÷ 
= 11.02 gallons
Now that you know how much gallons each car consumes, you can now get the gas price for the gallons.
1. Original SUV = 13.54 gallons × $2.59 per gallon = $35.06
2. Hybrid SUV = 11.02 gallons × $2.59 per gallon = $28.54
In order to check the difference, you have to subtract.
- $35.06 - $28.54 = $6.52 (this is the amount of money that you can save driving 237 miles in the hybrid SUV compared with the original SUV)
