The periodic table organizes elements according to similar properties in order to predict the characteristics of an element just by looking at its position on the table. Earlier the periodic table was used to predict the chemical and physical properties. But …
The noble gases are the chemical elements in group 18 of the periodic table and were previously referred to as the “inert gases” due to the fact that their filled valence shells (octets) make them extremely nonreactive.
Alkaline earth metals are the second group of the periodic table. This family includes the elements beryllium, magnesium, calcium, strontium, barium, and radium (Be, Mg, Ca, Sr, Ba, and Ra, respectively). Group 2 elements share common characteristics. Each metal is …
The Group 1 elements other than hydrogen are called the alkali metals. The Group 1 elements are: Hydrogen Lithium Sodium Potassium Rubidium Caesium Francium The Group 1 metals are all highly reactive metals that are so reactive that they are generally …
Right side group elements of columns 13, 14, 15, 16, 17 and 18 of the periodic table are known as P- Block Elements. These elements have 3,4,5,6,7 and 8 electrons in their outer most shell respectively and the last …
Electrochemistry: Electrochemistry is the Study of relationship between chemical energy and electrical energy and how one can be converted into another. Some of the important metals like Chlorine and Florine are produced from methods of electrochemistry. Battery and fuel cell …
Conductance of electrolytic solution:- Electrolytes conduct electricity by decomposition. Electrical resistance:- If voltage v is applied to the ends of the conductor and current “I” flows through it, then the resistance “R” of the conductor is V/I (ohm). Electrical conductance:- The reciprocal of electrical resistance …
Electrode Potential:- The electrical potential difference set up between metals and its ions in the solution is called electrode potential. Cell potential or EMF of a cell:- The difference between the electrode potential of the two half-cell is known as cell …
