Hurry will mark brainliest if correct what is the nuclear binding energy of an atom that has a mass defect of 1.643 10–28 kg? use e = mc2. (remember: the speed of light is approximately 3.00 108 m/s.) 1.83 10–46 j 4.93 10–20 j 1.48 10–11 j 5.48 1045 j

The energy which is required to split a nucleus into its discrete neutrons and protons is said to be nuclear binding energy.

Using the formula for nuclear binding energy:

E = Δmc²

where,

E = nuclear binding energy

Δm = mass defect

c = speed of light

Substitute the given value of mass defect and speed of light in above formula:

E =

E =

= Joule.

E=

Thus, nuclear binding energy of an atom is .

b..

is the correct one

explanation:

covalent bonds form as valence electrons are shared between two atoms. lewis structures and structural formulas are common ways of showing the covalent bonding in organic molecules. formal charge describes the changes in the number of valence electrons as an atom becomes bonded into a molecule.
