In an experiment to learn if substance M can help restore memory, the brains of 22 rats were treated to damage their memories. The rats were trained to run a maze. After a day, 11 rats were given M, and seven of them succeeded in the maze; only two of the 11 control rats were successful. The z test for "no difference" against "a higher proportion of the M group succeeds" has what values for the z-statistic and P-value

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.
