Answer this multiple choice question for 30 points and !

Step-by-step

To answer this question, we can simplify each expression and then substitute n.  

If you use a calculator, you can just plug-in n=2 to see which one is the greatest.

A. n^5*n^2/n^4 = n^(5+2-4) = n^3

B. n^2*n^3/n = n^(2+3-1) = n^4

C. (n^2)^3/n = n^(2*3-1) = n^5

D (n^5)^2/n^4 = n^(5*2-4) = n^6

As long as n>1, the higher power n has, the larger is the number.

Therefore (n^5)^2/n^4 = n^(5*2-4) = n^6 is the winner!

10/60

step-by-step explanation:

if you divide 10 by 60 the answer is 0.166666 while if you divide or solve the other problems it equals 0.6

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.
