distribution of scores was approximately bell-shaped and that the standard deviation was
approximately 41. round your answers to one decimal place as needed.
part 1 out of 2
within what boundaries would you expect 95% of the scores to fall?
about 95% of the scores should fall between
and
as

14

step-by-step explanation:

14 x 3 = 42

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.

80 the answer is 80
