PLEASE HELP Carbon-14 is a radioactive substance that decays over time. This expression models the
percentage of carbon-14 that remains in a sample after t years:
100()***
What does the number 5,730 represent?
the number of years it takes for the carbon-14 to decay completely
the original amount of carbon-14 in the sample
the number of years it takes for half of the carbon-14 to decay
the amount of carbon-14 in the sample after 100 years

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.
