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:

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

- calcium has greater affinity to bond with electron receptors than hydrogen does and hence, it has the ability to replace hydrogen in most of its compounds.

- lithium has 2 valence electrons in the product because it can make only 1 bond with hydrogen. beryllium has 4 valence electrons in the product because it can only make 2 bonds. it has fewer electrons than neon and can react with electron donors. each hydrogen has 2 valence electrons, the same as helium.

- the covalent bond formed between carbon and hydrogen is polar because carbon is more electronegative than hydrogen and it attracts the bonded electron pair closer to itself, thus giving hydrogen a partial positive charge.

- a hydrogen bond is a relatively weak bond that hydrogen atoms make with the electronegative atoms nitrogen, oxygen or fluorine.

so the best choice is a.) 2 calcium (ca) atoms
