Select the correct answer. You reflect triangle PQR, with vertices P(-2,-4), 91-3,-1), and R(-4,-4), across the y-axis to get triangle P'Q'R'. What are the coordinates of triangle P'Q'R?

whats the

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.

its an acute right triangle

step-by-step explanation:

the radius is 2 times the diameter.
