Given the following information: mass of proton = 1.00728 amu mass of neutron = 1.00866 amu mass of electron = 5.486 × 10^-4 amu speed of light = 2.9979 × 10^8 m/s calculate the nuclear binding energy (absolute value) of 3li^6. which has an atomic mass of 6.015126 amu. j/mol.

The nuclear binding energy of the given element is

Explanation:

For the given element

Number of protons = 3

Number of neutrons = (6 - 3) = 3

We are given:

M = mass of nucleus =

Calculating mass defect of the nucleus:

Converting this quantity into kg/mol, we use the conversion factor:

1 kg = 1000 g

So,  

To calculate the nuclear binding energy, we use Einstein equation, which is:

where,

E = Nuclear binding energy = ? J/mol

= Mass defect =

c = Speed of light =

Putting values in above equation, we get:

Hence, the nuclear binding energy of the given element is

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.
