Connect the whole numbers on the periodic table to indicate what they represent?

The correct answer is atomic number.  

Atomic number is the whole number that is written above the symbol for an element in the periodic table. The atomic number represents the number of protons in an element.

For example, the whole number 7 is written on the top right corner of the element N. This means that element N or nitrogen has atomic number 7. So N, nitrogen has 7 protons.

explanation:

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.
