>If A, G, H are the A.M., G.M., H.M. respectively between non-zero positive numbers a and b, then (a) A, G, H are in G.P. (b) A>G>H. In particular, if a = b = c, then A = G = H. (i) A sequence is said to be an arithmeticco-geometric sequence if terms of the sequence are the products..

In the Daniel cell, the valencies of zinc and copper are the same, i.e., n=2. However, the electrode potential of a cell in which the valencies of the two metals used in the two half cells are not same e.g., The two half-cell reactions are: Two electrons are released by one Cu-atom and only on..

Nuclear Stability and Neutron/Proton Ratio - It has been found that the stability of nucleus depends upon its neutron to proton (n/p) ratio. A plot of N (the neutron number) against Z (atomic number or number of protons) show that for stab..

The nuclei of atoms are made up of protons and neutrons. These two components of the nucleus are referred to as nucleon..

This is the number of protons present in the nucleus or the number of electrons present outside the nucleus. It is denoted by the letter Z. Atomic number (Z) = Nuclear charge or number of protons (p) = Number of electrons ..

Atomic Number - The number of protons or the number of electrons in an atom in its normal state is called the atomic number and is denoted by Z. The nucleus of every element contains Z protons and some number of neutrons. The ele..

The sum of the number of protons and neutrons in the nucleus of an atom is called the mass number. It is represented by the letter A. Mass number (A)= Number of protons (p) + number of neutrons (n) From the knowledge of atomic h..

>Each hydrogen atom is having one electron while its nucleus has one proton and so there is no net charge on each atom of hydrogen. The oxidation number of hydrogen in hydrogen molecule is zero. Electrons shared between two unlike atoms are counted with more electronegative atom..
