Sal has already finished five nights of the 45 math problems he was assigned if each math problem took him three fifths of a minute to finish and this pace continues which expression can be used to determine the amount of time it will take him to finish his remaining homework a. 45* 5/9 *3/5
b. 45* 5/9 divided by 3/5
c. 45 * 4/9 * 3/5
d.45 * 4/9 / 3/5

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.

hi how are you doing today? if you ever need just tell me
