atomicity of water

Representative Periodic Table for 8 Groups upto Calcium (Atomic Number -20) - Representative elements are those elements whose inner shells are complete and whose outer shell (valency shell) has 1 to 7 electrons. They are also called normal elemen..

Representative elements are those elements whose inner shells are complete and whose outer shell (valency shell) has 1 to 7 electrons. They are also called normal elemen..

The middle carbon atom that attaches to four carbon atoms in the carbon chain of an organic compound, is called a quaternary carbon atom. These carbon atoms are illustrated below. The hydrogen atoms attached to the primary (1 ..

The terminal carbon atoms that attaches to one carbon atom only, in the carbon skeleton of an organic compound, is called a primary (or 1°) carbon atom. ..

Like 1s-orbitals, 2s-orbitals combine by addition and subtraction of overlappingwavefunctions to form bonding and antibonding molecular orbitals. These are labeled as s 2s,and s *2s. These molecular orbitals have exactly the same shapes as s 1s and s *1s MOs but t..

Now if the H atoms are forced to come closer than the equilibrium inter-nuclear distance, the repulsive forces start predominating and the energy of the system increases sharply. ..

A hydrogen atom has a mass of 1.67 × 10 -27 kilogram. Express the mass of 4 × 10 2 hydrogen atoms in scientific notation. => 6.68 x 10 -25 kilogram or 6.68 x 10 29 kilogram or 6.68 x 10 -29 kilogram or 6.68 x 10 25 kilogram..

Atom is the smallest particle of an element, which may or may not have independent existence. It is made up of subatomic particles like electrons, protons and neutrons. Atoms of one type of element differ from those of the other due to different number of subatomic particles. ..

Like halogens, hydrogen is diatomic (H 2 ) whereas metals are monoatomi..

Two hydrogen atoms mutually share one electron each with an atom of oxygen to form a water molecule (Fig. 3.8). Note ..
