Find the range of values of m for which the roots of the equation below is real. 3x^2 - 3mx + (m^2 - m -3) = 0

The range is -2 ≤ m ≤ 6

Step-by-step explanation:

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.

idk the answer i want to say 10 but then it would be equal so try 9 but then yeah so yeah we love edgen
