4. A plane flew 2,190 kilometers from Chicago to Flagstaff. Another plane flew 2,910
kilometers from Chicago to Oakland. How
much farther did the plane that flew to
Oakland fly than the plane that flew to
Flagstaff?

i'm pretty sure it's 477,585,296, but perhaps my math is incorrect.

78.59 is the mean

step-by-step explanation:

answer: approximately 206 bones

i hope this u out a branlist and a would be greatly appreciated :

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.
