Two isotopes of a certain element have binding energies that differ by 3.8580 mev. the isotope with the larger binding energy contains one more neutron than the other isotope. find the difference in atomic mass between the two isotopes, by taking the energy equivalent of 1 u to be 931.50 mev. express your answer in atomic mass units.

The difference in atomic mass between the two isotopes is 1.00452329 atomic mass unit.

Explanation:

For an isotope-I (heavier)

Mass of an isotope-I=M

Number of neutrons = n+1

Number of protons = p

For an isotope-II

Mass of an isotope-II=M'

Number of neutrons = n

Number of protons = p

Difference in binding energy:

(general binding energy expression)

Binding energy difference between two isotopes:

..(1)

The difference in atomic mass between the two isotopes is 1.00452329 atomic mass unit.

a. hope i'm right

explanation:

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
