Hannah is performing an experiment by randomly drawing a slip of colored paper from a bag. There are 6 different-colored strips of paper of equal size with one strip of each color in the bag. The following frequency table shows the number of times she drew each color of paper.

72 is the answer to this problem

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.
