What does Hund's rule state?
telo118 [61]

Answer:

Explanation:

Hund's Rule of Maximum Multiplicity states that electrons go into degenerate orbitals of sub-orbitals(p, d and f) singly before pairing commences.

Hund's rule is useful in determining the number of unpaired electrons in an atom. Hence, it explains some of the magnetic properties of elements.

An element whose atoms or molecules contain unpaired electrons is paramagnetic.

The element whose atoms or molecules contain orbitals that are all filed up with paired electron is diamagnetic.

Scientists found a fern fossil in some rock layers of the Grand Canyon. They estimated that a sample of one of the fossils origi
icang [17]
This question is dealing with the half-life of carbon-14 which can be used to determine the age of a substance according to the following equation:

t = [ln(N/No)/(-ln2)] · t1/2

N = # of carbon-14 atoms presently = 250 atoms
No = # of carbon-14 atoms initially = 1000 atoms
t1/2 = half-life = 5730 years for carbon-14

We can now input all of the information into the formula to find the age of the fossil:

t = [ln (250/1000)/-ln2] x 5730 years

t = 11460 years

The fossil should be found to be roughly 11,460 years old.
