The properties of compound are different from its constituent elements. Water which is a compound of oxygen and hydrogen has property to extinguish fire though its constituent elements do not...

(a) Yes. The atoms of all the three elements lithium, sodium, and potassium have one electron in their outermost shells. (b) Both helium (He) and neon (Ne) have filled outermost shells....

For hydrogen like atom. En \(\propto\) -\(\frac{Ƶ^2}{n^2}\) En = -k\(\frac{Ƶ^2}{n^2}\) for hydrogen atom- E4 = -k\(\frac{(1)^2}{4^2}\)  E4 = \(\frac{-k}{16}\)  given, E4 = € \(\because\) k = -€ x 16----(1) For Li+2 E1 = \(-\frac{k(3)^2}{1^2}\)  = -k x 9 using equation (1) we get E1 = € x 16 x 9 E1 = 144 €

Hydrogen can be considered a cleaner fuel because its burning produces water vapour which is non-polluting. However, due to explosive nature of hydrogen, its storage and transportation is difficult

Inter and Intramolecular hydrogen bonding.

In sulphur dioxide (SO2), the oxidation number (O.N.) of S is +4 and the range of the O.N. that S can have is from +6 to –2.  Therefore, SO2 can act...

Atomic hydrogen atoms are produced by the dissociation of dihydrogen with the help of an electric arc. This releases a huge amount of energy (435.88 kJ mol–1 ). This energy...

Deuterium and tritium. The importance of heavier isotopes of hydrogen is in nuclear reactor.

Homolysis of HCl does not takes place and in the case of HI homolysis takes place but the iodide free radical combine with the similar free radical to form I2...
