In math math what is the difference between independent and dependent variables

Independent variables means it is not affect by the other variables(be it unknown or the dependent ones).

Example being the number of hours you take to travel from one place to another.

But a dependent variable's value is affected by the independent variables. So taking the earlier example, the speed you travelled at is based on the time taken and the distance of the place from the other.

So, to sum it up, an independent variable will change the value of a dependent variable, but a dependent variable cannot change the value of an independent variable, and the value of the dependent variable is determined by the value of the independent variable.

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.
