which of the following properties is being utilized. xy=yxcommutative property of addition distributive property identity property of multiplication commutative property of multiplication

We have the expression:

We have two factors, x and y, and we altered the order of them, but the result does not change and the equality stands: x*y=y*x.

This is the commutative property of multiplication.

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.
