<em>Answer:</em>

  • The atom consist of three parts, proton, neutron and electrons. The electrons determine that i will combine or beak from other substances.

<em>Explanation:</em>

The atom consist of three parts which are following

  • proton
  • neutron
  • electron

The proton and neutron form nucleus of an atom. It is present at center of an atom. They have positive charges, while electrons remained outside the nucleus in particular energy levels or shell around the nucleus.

During combination or breaking of substances ,only arrangements of electrons take place. The valence shell electrons decide whether they have to combine or not, while nucleus remained unchanged during any reactions.

The binding energy in MeV per atom is - 63284.56 Mev.

The amount of energy needed to detach a particle from a system of particles or to disperse every particle in the system is known as the binding energy. Subatomic particles in atomic nuclei, electrons attached to atom's nuclei, and atoms and ions bonded together in crystals are three examples of where binding energy is very relevant.

If we have a nucleus with Z protons and N neutrons and mass MA, where A = Z + N then its binding energy in MeV is given by: Eb(MeV) = (Zmp + Nmn - MA) x 931.494 MeV/u

Mass of atom = 69.955264 amu

Mass of proton = 1.007825 amu

Mass of neutron = 1.008665 amu

Binding energy, Mev = (Zmp + Nmn - M) × 931.494MeV/u

                                    = ( 1.007825 + 1.008665 -  69.955264) × 931.494

                                    = - 67.938774 × 931.494

                                    = - 63284.56 Mev

Therefore, the binding energy in MeV per atom is - 63284.56 Mev.

How does a molecular formula differ from a structural formula?
mr Goodwill [35]

Explanation:

Molecular formulas show correct and accurate number of each type of the atoms which are present in molecule.

On the other hand, structural formulas show arrangement of atoms and covalent bonds between them.

For example,

The molecular formula for carbon dioxide is CO_2

The structural formula is O = C = O
