Elizabeth is making a volcano for her science project. she determines that the radius of the base of the volcano needs to be 2.5 inches in the slant height needs to be 8.5 inches. how much paper will she need to cover the outside of the cylindrical volcano? Elizabeth will need ___ pi in^2 of paper.

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.
