atomicity of gases

Atomicity of Gases - Homoatomic molecules have different atomicity..

Atomicity is the number of atoms of an element present in one molecule of that element. They can be monoatomic (He), diatomic (H 2 ), triatomic (O 3 ) and polyatomic (S 8 ..

Atomicity of Hydrogen and Chlorine Let up take the example of the same reaction between hydrogen and chlorine. We saw earlier that; ..

Kinetic Theory of Gases - The word 'Kinetic' means due to motion. The Kinetic Theory of Gases is based on the idea that gases consist of atoms and molecules moving ceaselessly and randomly with all possible velocities in all directions. Each of these gas part..

Velocity of Sound in Different Gases - As seen from equation (1-28), the velocity of sound in a gas depends on g , the ratio of the principle specific heats of the gas. This, in turn, depends on the atomicity of the gas. An approximate equation connecting g and the degrees of fr..

Properties of Gases in Terms of Molecular Motion - Gases, as well as mixture of gases, behave as seen above, with regard to changes in temperature, pressure or both. The following assumptions can be made on the basis of the kinetic theory of gases: A molecule..

are the most compressible because of large empty space between inter-particles Arrangement of particles The atoms or molecules are tightly packed. There exists a long range order in solids The atoms and molecules are packed slightly loose. Only short range order exists The parti..

. In 1793, he left for Manchester to teach physics and chemistry in a college. In 1801, he observed and discovered the law of expansion of gases on heating. He also enunciated the law of partial pressures and found methods of determining vapour pressure of gases. He invented the..

>The mass of electrons is negligible compared to the mass of the protons. Ordinary hydrogen is the only element that has no neutron in it. According to Bohr electrons revolve around the nucleus in fixed orbits called K, L, M, N etc. The energy of the shells increases as the distance form the nucleu..

Atoms and Ions - Listed below are some elements that attain the octet configuration of Noble gases. Let us see how this happens. Study the given table: Elements Atomic number Electronic configuration Loss/gain of e Sodium 11 281 1 electron lost Oxygen S 16 2 electrons ..
