The value of x that makes 2x equal 10 is __ 3
a. a little more than
b. a little less than
c. exactly

A

Step-by-step explanation:

-2x = 10

-2x ÷ 10 = 5

-5 = x

you do not divide 10 by 10 because they cancel each other out, but you do divide 10 into 2 so you can find 1 x.

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.
