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..

Lithium - For refining copper and nickel. For producing thermo nuclear energy for propelling rockets and guided missiles. For the manufacture of various alloys such as lithium lead alloy, lithium aluminium alloy etc. Lithium and its compounds are used as reagents in a number of organic sy..

Sodium Carbonate (Na 2 CO 3 ) - Sodium carbonate exists as anhydrous (Na 2 CO 3 ) and also as hydrated salt. The decahydrated salt (Na 2 CO 3 .10H 2 O) is known as washing soda while the anhydrous salt is called soda ash. It occurs native as Na 2 CO 3 .NaHCO 3 .H 2 O) in Egypt, ..

The total number of protons and neutrons present in one atom of an element is known as its mass number. Mass number = number of protons + number of neutrons It can also be said that: Mass number = Atomic number..

The nuclei of atoms are made up of protons and neutrons. These two components of the nucleus are referred to as nucleons. The electrons occupy the space outside the nucleus. Since an atom is electrically neutral, the number of protons in the nucleus is exactly equal t..

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 neutron..

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 electrons, having the same ch..

Avogadro's number is the number of elementary units (atoms, molecules, or ions) present in one mole of a substance, and it is equal to 6.023 x 10 2 3 . The concept of a mole being equal to a number 6.023 x 10 2 3 is akin to the concept of a dozen being equal to a 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..
