Ihave 11 red marbles and 4 blue marbles in a bag if i choose one what color will it be

11/15 red, 4/15 blue

Step-by-step explanation:

There are 15 marbles in all so that is the denominator.

The numerator is the number of marbles for each color.

So...

11 red marbles / 15 total marbles

4 blue marbles / 15 total marbles

if x = 1, then the answer is 3.5

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.
