Chemical Properties of Alkaline Earth Metals
Chemical Properties of Alkaline Earth Metals - As alkaline Earth metals have low ionization energies and high electropositive character, they are very reactive and have a strong tendency to lose valence electrons, though less than alkali metals. The reactivit..
Chemical Properties of Alkaline Earth Metals
As alkaline Earth metals have low ionization energies and high electropositive character, they are very reactive and have a strong tendency to lose valence electrons, though less than alkali metals. The reactivity of these elements increases on going down the group. The chemistr..
Stability of carbonates of alkali and alkaline Earth metals
All the carbonates of alkali metals are quite stable towards heat except Li 2 CO 3 , which decomposes easily on heating. The instability of Li 2 CO 3 is due to the small size of lithium ion, which cannot stabilize the bigger carbonate ion. The carbonates of alkaline Earth meta..
The Earth as a Magnet
About AD1600, William Gilbert, who was a court physician of Queen Elizabeth of England, performed certain experiments using spherical lodestones. When he placed small, pivoted magnetic needles at different positions on this sphere, he found that their behavior was quite similar to that of magnetize..

Structure of the Earth - During the formation of the Earth, cooling of gaseous mixtures took place and molten earth condensed to form different earth zones or layers. Each layer that formed on top of the other had a definite chemical composition and thus a di..

The Earth's Early Development
Scientists theorize that the earth began as a waterless mass of rock surrounded by a cloud of gas. Radioactive materials in the rock and increasing pressure in the earth's interior gradually produced enough heat to melt the interior of the earth. The heavy ..

Tutor was excellent, asnwered the question rapidly and provided the information I needed to understand the problem.
This Tutor Vista is GREAT! loved this session, it helped me heaps.
all my questions were answered in a very clear way and i learned a new math rules which i did not know this service is very helpful - mike
Thank you very much for helping to me is very important to have my lessons. Because you manage to take good notes in school thank you Tutor Vista
