How is solving for speed similar to solving for time? They both require that two numbers be added.
They both require that two numbers be subtracted.
They both involve writing a rate.
They both use the same units of measure,

They both involve writing a rate.

Step-by-step explanation:

i got it right

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.

answer: 72: 111
