You receive a package of tiles. the total charge is $625 for 41 tiles, round to estimate the per tile cost. round to estimate the per tile cost.

Depending on where you round to, you can estimate the tiles are $15 to $16 each. I rounded $625 to $630 and 41 to 40 which is how I got $15.75 which if round to the nearest whole number is $16.

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.
