Sam works a total of 30 hours at his two jobs. His job as a yard specialist pays $8 am hour. His job as a babysitter pays $6 an hour. He needs $130 each week. Write a
system of equations that shows the number of hours that he can work at each job.

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.
