Atomic mass is the number at the bottom of the box. Look up all four answer choices and then choose the answer with the highest number.

Stirring will not separate anything. When ever you get a "not" question look for the item that doesn't seem to have anything in common with the other choices.

Metals are the ones from the staircase line all the way to the left. This is most of the elements.

Solution is a liquid combined with a solid. Na by itself would be an element but since it is combined with Cl that is what makes it a compound. Since they are chemically combined they can not be a mixture.

Since water molecules, salt and dihydrogen oxide are chemically combined they can not be separated physically. But the salt in salt water is not bonded to the water so you could separate them from each other by boiling.

The sugar and coolaid flavoring would get dissolved in the water.

Methods of exposure include: breathing in (inhaling), touching and consumption (eating or drinking).

This happens to make clouds, water vapor enters earth's atmosphere and then cools down comes together as it turns into liquid and makes a cloud.

Elements from the same group/family (same vertical column) have the most similiar properties.

Noble gases do not participate in bonding because they have a full outer energy level.
