Water
About 70-73% of earth is covered by water. Water is available in the form of oceans, seas, rivers, lakes, ponds, pools, polar ice caps and water vapour and this forms the hydrosphere. The main component of hydrosphere is water. Water exists in all the three forms i.e., solid (snow),..
Triple Bond
Nitrogen Molecule Nitrogen atom has five electrons in its valence shell. It requires three more electrons to acquire a stable configuration of the nearest noble gas (neon). This is done by mutually sharing three pairs of electrons as shown below. ..Uses of Noble Gases
Argon is used mainly to provide an inert atmosphere in high temperature metallurgical processes (arc welding of metals or alloys) and for filling electric bulbs. It is also used in the laboratory for handling substances that are air-sensitive. Helium is a non-flammable and light gas. Henc..
Mining of petroleum
Petroleum is brought to the surface by drilling a hole in the Earth's crust and sinking pipes deep down through the impervious cap rock. Natural gas first comes out under high pressure. Then, petroleum is pumped out, collected in tanks and transported, for further processing. ..

Variation in a period
The atomic radius abruptly increases in the case of noble gas element Neon as it does not form covalent bonds. So the value of Neon radius is Van der Waals radius which is considerably higher than the value of other covalent rad..

This explained everything to me clearly and helped me so much and I think it has made a difference in my understanding. Its gone from small to big understanding ,I think it is a magnificent tutoring - Elizabeth
She should be the head of Tutor Vista. She knows how to treat her students. Her teaching style is spectacular.
The tutor really touched the right methods and formulas that would help me the most as well as a helpful practice sheet to test my knowledge of the subject. Great work!
My grades increased drastically with Tutor Vista and I'll definitely recommend this to all students who want to do better in their school. Not only do we learn, we also have fun!
Looking for More Help!
