JAIN PHILOSOPIIY & MODERN SCIENCC The nature of the positive and negative particles of a hydrogen atom is as follows
Electron has a diameter of 115,000,000,000,000 inch, a speed of 1,300 miles per second and its weight is 1/2,000 part of a hydrogen atom
Proton has a diameter nearly 10 times that of an electron and its weight 18 equal to 164/1,000,000,000,000,000,000,000,000 gramme
The description of the hydrogen atom can be summarised thus It has a single proton as nucleus; a single electron rotates round it at a speed of 1300 miles per second, practically the whole mass is concentrated in the nucleus and its diameter is only 2 billionth part of an inch It is astonishing but true that a major part of the 'atom' is empty space If we imagine a 'proton' to assume the size of an amlafrut (ie about an inch in diameter), the empty space betwccn the orbit of the electron and proton would be 666 yards and 2 feet OTHER ATOMS In the atomic table, after hydrogen, comes Helium Its nucleus has two protons Two electrons are constantly rotating round the nucleus In the same way there is a consistent increase of one clectron in each element in the sequence. Thus, the third element Lithium and the fourth Beryllium have 3 and 4 protons and electrons respectively; and so on up to the last and the heaviest natural element 'Uranium', in the
