The Pyramid of Khufu in Giza, Egypt was the world's tallest free-standing structure for more than 3,500
years. Its original height was about 144 meters. Its
base is approximately a square with a side length of
231 meters.
The diagram shows a cross section created by dilating
the base using the top of the pyramid as a center. The
cross section has side length of 154 meters.
What is the height of the cross section?

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.
