A water pipe mounted on the ceiling has a leak and is dripping onto the floor below, creating a circular puddle of water. The area of the puddle is increasing at a rate of 11cm2/hour. Find the area and radius of the puddle after:1 minute92 minutes5 hours1 day

step-by-step explanation:

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.
