The Reactivity Series of Metals
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..
Table lists out atomic number, electronic configuration
. Any atom with this configuration will be in the minimum state of energy, hence stable. Atoms try to attain the octet or the duplet configuration by either loss or gain of electrons. Metal atoms tend to lose electrons. Non metal atoms tend to gain electrons. Example: Lithium ha..

Very fast and clear. Made sure I understood the concepts instead of giving the answers to the problem.
This Tutor Vista is GREAT! loved this session, it helped me heaps.
It was a great pleasure working with this tutor was able to take me through the steps of my math problems which was very helpful because since I don't have lots of experience with math by the tutor doing the steps it helps me understand a great deal. Im so excited that Im finally getting this amazing service. We got so much done. thank you.
My son really liked the tutors approach! thanks so much he left the computer feeling postive and confident about his test tomorrow. and that make us (mom and dad) happy!!!!!!
