3. Valency
The members of group VA generally show trivalent character but nitrogen shows more than one valency ranging from +1 to +5. Example: Oxide of Nitrogen N 2 O NO N 2 O 3 NO 2 N 2 O 5 Name Nitrous Oxide Nitric Oxide Nitrogen Trioxi..
Determination of the Structure of a Complex Using Werner's Theory
Example: In the complex between CoCl 3 and NH 3 the ionizable chloride ions are found by precipitation with AgNO 3 . The remaining Cl and NH 3 are present around the central Co in such directions so as to minimize repulsion and are linked by secondary valencies..

Formation of magnesium chloride
Magnesium whose atomic number is 12, has 2, 8, 2 configuration. So, it has two electrons in its valence shell. The electronic configuration of chlorine (At. no. 17) is 2,8,7. So it has seven valence electrons. Since, magnesium has two electrons in excess of the neon c..

Oxidation states
These elements have five electrons in the valence shell. The loss of five electrons is quite difficult because of energy considerations. Hence they do not form ionic compounds by loss of 5 electrons. On the other hand, these elements can also gain three electrons to c..
The Reactivity Series of Metals
Although most metals are usually electropositive in nature and lose electrons in a chemical reaction they do not react with the same vigour or speed. Metals display different reactions towards different substances. The greater the ease with which an element loses its electrons and acquir..

I love the interaction and ability to explain the process of math problem in depth! Would like see the same for all future lessons one on one! THANK YOU!!!
Even though I don't feel good, the tutor helped me by totally helping me understand!
Very good, Tutor was clear and guided me through the whole algebra problems
This Tutor Vista is GREAT! loved this session, it helped me heaps.
Looking for More Help!
