Noble Gases is the answer. These elements have a full outer shell composed of eight valence electrons, meaning that they do not need to gain electrons from other elements in reactions, making them nonreactive (inert).

Answer:
C. They have the same number of protons.
Explanation:
Even though in isotopes, there's uneven number of neutrons, there's always same number of protons.
Hope it helps.
Answer:
To make a 3.50 M solution, 38.5 moles of solute will be needed if 11 liters of solution are required.
Explanation:
Molarity is defined as a concentration unit that indicates the number of moles of solute per liter of solution. That is, it indicates the number of moles of solute that are dissolved in a given volume. Then, the molarity is calculated by dividing the moles of the solute by the liters (volume) of the solution:
Molarity is expressed in units ().
So, knowing the definition of molarity, you can apply a rule of three as follows: if by the definition of molarity in 1 L of solution there are 3.5 moles of solute, in 11 L of solution how many moles of solute are there?
moles=38.5
<u><em>To make a 3.50 M solution, 38.5 moles of solute will be needed if 11 liters of solution are required.</em></u>
