Which numbers are a distance of 5 units from 8 on a number line? select the location on the number line to plot each point.

  and

Step-by-step explanation:

Observe the number line attached.

In order to find which numbers are a distance of  from   on a number line, you can follow these steps:

First step: You must locate the number   on the number line.

Second step: Move to the left. Notice that the distance between the numbers   and   is

Third step: Move  to the right. Observe that the distance between the numbers  and   is

You can also verify this through the following addition and subtraction:

Therefore, the numbers that are a distance of  from   on a number line, are:

  and

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.
