Selena is graphing the inequality x less-than negative 2. She begins by drawing a number line and placing an open circle at –2. A number line going from negative 7 to positive 3. An open-circle is at negative 2.

Which could be Selena’s next step?

shading the number line to the left of the open circle

shading the number line to the right of the open circle

shading the number line to the right and left of the open circle

shading in the open circle

a is the right answer

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.
