Afinancial planner wants to invest $8000, some in stocks earning 15% annually and the rest in bonds earning 6% annually. how much should be invested at each rate to get a return of $930 annually from the two investments? (hint: let x = the amount, in dollars, invested at 15%, and let y = the amount, in dollars, invested at 6%.)

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.
