Sami planned to spend the weekend camping, so on Friday night he drove from his house to the nearest campsite at a speed of 60 miles per hour. After the weekend was over, he
drove the same way home, but drove at a speed of 40 miles per hour because of the bad
weather. If he spent a total of 7 hours driving, how many hours did the trip to the campsite
take?

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.

d.) yes, because the volume of the cone is greater than the volume of the sphere
