Barry is trying to calculate the distance between point E(3, 1) and point F(4, 7). Which of the following expressions will he use? Your

square root of the quantity of 7 minus 1 all squared plus 4 minus 3 all squared

­

square root of the quantity of 7 minus 3 all squared plus 4 minus 1 all squared

­

square root of the quantity of 7 minus 4 all squared plus 3 minus 1 all squared

­

square root of the quantity of 4 minus 7 all squared plus 1 minus 3 all squared

b) well because you get well

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.

i would say b) is your answer

sorry if im wrong

step-by-step explanation:

look at the picture i have filled out a table for it. hope this .
