A ladder has to be leaned on a tall pole so the top of the pole can be reached. The height of the pole is 30 ft., and the ground distance from the foot of the ladder to the pole is 15 ft. Draw a diagram to model the problem.
What is the angle at which the ladder must be leaned to reach the top of the pole? Show all work and label the answer. Round to the nearest tenth, if needed.

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.
