Line a) the common endpoint of two segments or rays that form the "corner" of an angle line segment b) part of a line that has two endpoints ray c) a location, has no dimension point d) part of a line that has one endpoint and continues in one direction infinitely vertex e) an infinite number of points extending in opposite directions that has only one dimension

step-by-step explanation:

options

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.
