Hello Debabrat,
Both MBA and M.Sc are good options in their respective fields. With MBA, you get expertise in management field. It opens up a lot of opportunities depending on the specialisation you opt. Most students opt for MBA and is recommended if you are not interested in pursuing higher education in the technical line. M.Sc, on the other hand, enriches your technical knowledge further. Various job profiles available for graduates in M.Sc. Chemistry is listed below:
Analytical Chemist
Teacher
Lab Chemist
Production Chemist
Research & Development Manager
R & D Director
Chemical Engineering Associate
Biomedical Chemist
Industrial Research Scientist
Materials Technologist
Quality Controller
Production Officer
Safety Health and Environment Specialist
Major employment areas recruiting graduates in M.Sc. Chemistry are given below:
Pharmaceutical Companies
Agrochemical Industry
Petrochemical Industry
Toiletry Industry
Plastic Manufacturing Units
Chemical Manufacturers
Food Processing Firms
Paint Manufacturing Companies
Plastics Industries
Textile Industries
Educational Institutes
Independent laboratories
Environmental Law

Space Exploration Agencies
Forensic Science Department
Ceramics Industry
Paper Industry
Military Systems Department
Therefore, it depends on your sole interest on which course you wish to pursue further.

Hi Neeraj,
An isotope is a form of a chemical element whose atomic nucleus contains a specific number of neutron s, in addition to the number of proton s that uniquely defines the element. The nuclei of most atom s contain neutrons as well as protons. (An exception is the common form of hydrogen, whose nucleus consists of a lone proton.) Every chemical element has more than one isotope. For any element, one of the isotopes is more abundant in nature than any of the others, although often multiple isotopes of a single element are mixed.
Some carbon-14 is found in nature. An atom of carbon-14 contains 6 protons and 8 neutrons and is denoted 14 C. Over time, 14 C decays into 12 C.
Sometimes the isotope of an element is denoted by writing the nucleon number after the chemical symbol, and not as a superscript. Thus, some texts will denote carbon-14 as C-14 or C14 instead of 14 C.
Certain isotopes of elements are unstable, giving off ionizing radiation, also known as radioactivity. Such an isotope is called a radioisotope. Carbon-14 is a radioisotope of carbon. In the case of an element that is radioactive in all its known forms, such as uranium (U), certain isotopes are more radioactive than others, and/or give off different proportions of the various types of ionizing radiation.
All the best.

Hi Manish,
Slater's Rules:
1) Write the electron configuration for the atom using the following design;
(1s)(2s,2p)(3s,3p) (3d) (4s,4p) (4d) (4f) (5s,5p)
2) Any electrons to the right of the electron of interest contributes no shielding. (Approximately correct statement.)
3) All other electrons in the same group as the electron of interest shield to an extent of 0.35 nuclear charge units
4) If the electron of interest is an s or p electron: All electrons with one less value of the principal quantum number shield to an extent of 0.85 units of nuclear charge. All electrons with two less values of the principal quantum number shield to an extent of 1.00 units.
5) If the electron of interest is an d or f electron: All electrons to the left shield to an extent of 1.00 units of nuclear charge.
6) Sum the shielding amounts from steps 2 through 5 and subtract from the nuclear charge value to obtain the effective nuclear charge.
Examples:
Calculate Z* for a valence electron in fluorine.
(1s2)(2s2,2p5)
Rule 2 does not apply; 0.35 6 + 0.85 2 = 3.8
Z* = 9 3.8 = 5.2 for a valence electron.
Calculate Z* for a 6s electron in Platinum.
(1s2)(2s2,2p6)(3s2,3p6) (3d10) (4s2,4p6) (4d10) (4f14) (5s2,5p6) (5d8) (6s2)
Rule 2 does not apply; 0.35 1 + 0.85 16 + 60 1.00 = 73.95
Z* = 78 73.95 = 4.15 for a valence electron.
Shielding:
The first ionization energy for hydrogen is 1310 kJmol1 while the first ionization energy for lithium is 520 kJmol1. The IE for lithium is lower for two reasons;
1) The average distance from the nucleus for a 2s electron is greater than a 1s electron;
2) The 2s1 electron in lithium is repelled by the inner core electrons, so the valence electron is easily removed.
For reason #2 the inner core electrons shield the valence electron from the nucleus so the outer most electron only experiences an effective nuclear charge. In the case of the lithium the bulk of the 1s electron density lies between the nucleus and the 2s1 electron. So the valence electron 'sees' the sum of the charges or approximately +1. In reality the charge the valence electron experiences is greater than 1 because the radial distribution show their is some probability of finding the 2s electron close to the nucleus.
All the best.
