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. Th..
Comparative Properties of Metals and Non-Metals
. Non-metal exhibit both electrovalency or covalency. Deposition during electrolysis They are always deposited at the cathode. They are always deposited at the anode. Redox reaction These lose electrons and hence get oxidized. These gain electrons and hence get reduced. Redox ag..

..Metals
All elements except hydrogen, which form positive ions by losing electrons during chemical reactions are called metals. Thus metals are electropositive elements. They are characterized by bright lustre, hardness, ability to resonate sound and are excellent c..
a) With Non-Metals
With hot concentrated nitric acid, non-metals are oxidized to their oxide while the acid itself gets reduced to nitrogen dioxide. In all the reactions described below, the nascent oxygen is released during the thermal decomposition of the acid, wh..

Calcium hydroxide, which is a base, reacts with carbon dioxide to produce a salt and water. Since this is similar to the reaction between a base and an acid, we can conclude that nonmetallic oxides are acidic in nature..

Tutor Vista perceived the math apps well and I enjoyed getting to work with Tutor Vista - Savannah
I uploaded a worksheet and I wanted to follow it with the tutor so I could learn the technical parts. It took just a few minutes to get the understanding of what I needed with the tutor. I even get through all the examples on the sheet in 25 minutes that we were focused on it.
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.
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!
Looking for More Help!
