10. Let's list the elements of each pair of overlapping sets. Then make a set of common elements in each case. a) b) c) Q P B M A А b i 2 1 7 2 3 6 4 3 4 9 8 12 5 d 10 N C u 15 11. From the given sets, list the common elements in separate sets. Show elements and the common elements of each pair of sets in diagrams. a) A = {1, 2, 3, 4, 5, 6, 7, 8, 9} and B = {2, 3, 5, 7} b) P = {2, 4, 6, 8, 10} and Q = {4, 8, 12, 16}​

a = 3.14

b = 18

c = 18/5 or 3.6 or 3 3/5

step-by-step explanation:

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.
