Valerie and Marco who are cousins are going on a trip to see their grandparents. Each child rides in their own family’s car at the end of the trip valeries family determined they traveled at an average rate of 47.5 miles per hour Marcos family determined they traveled at an average rate of 55 miles per hour

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.

slope is 35 and 20 miles is the y-intercept.
