Bohr-Bury Scheme
Arrangement of Electrons in an Atom (Bohr-Bury Scheme) - Electrons revolve around the nucleus in different energy levels or shells and each shell is associated with definite energy. The energy of the K shell is the least while those of L, M, N and O shells increases progressively. We also..

Maximum number of electrons that can be accommodated in a shell is given by 2n 2 where n = shell number For 1 st energy level, n = 1Maximum number of electrons in 1 st energy level = 2n 2 2 x (1) 2 = 2 For 2 nd energy level n = 2Maximum number of electrons in the 2 nd energy level = 2n..
Arrangement of Electrons in an Atom (Bohr-Bury Scheme)
Electrons revolve around the nucleus in different energy levels or shells and each shell is associated with definite energy. The energy of the K shell is the least while those of L, M, N and O shells increases progressively. We also know that any system that has least energy is the most stable.1 s..

Fossil Fuels
Meaning - Fossil fuels are energy-rich, combustible forms of carbon or compounds of carbon formed by the decomposition of biomass buried under the Earth over millions of year..
Formation
Petroleum is believed to have been originated from the remains of sea organisms. The micro organisms have largely contributed to the formation of petroleum. Due to the effect of heat, pressure and catalytic action of anaerobic bacteria, the buried remains of sea organisms decomposes very..
Formation of fossil fuels
It is believed that plants and animals that died due to various natural calamities like cyclones, floods, forest fires, earthquakes etc., got buried under soil sediments over a period of millions of years. The remnants of buried plant and animal matter (organic) got subject..

Modes of Waste Disposal
There are different scientific techniques of waste disposal, which depend upon the nature of the waste. Most solid wastes are buried in urban areas as land fills. Some solid wastes like plastics, metals, papers are recycled. Industrial wastes are treated in special plants and valuable wa..

I was very pleased with my sessions the tutors were a great help and helped me through the problems step by step - Molly
I need tutoring from tutorvista till th end of my schooling. Tutors are not only experts they are brilliant enough to make a student like me understand the concepts of differentiation and functions.
All of my 3 kids are getting good grades with the help of Tutor Vista, You are Great-Thank you
Math is no more a problem at all for me, an hour tutoring everyday with an online tutor is helping me to get good grades
