Lanas family is planning a rectangular garden. they make a scale diagram of the garden using a scale of 1 in. to 0.5 meter. if the length of of the scale diagram is 24 in., and its width is 16 in., what is the perimeter of the actual garden?

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.
