Diragio Lawn Care cuts 42 lawns every week. Each lawn uses 3 16 of a tank of gas when it is cut (on average). Part A: If the lawnmower had no gas at the start of the week, how many times would it be completely filled?

answer: a.   one is a factor of every whole number since every number is divisible by itself.

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.
