General introduction, electronic configuration, occurrence, variation of properties, oxidation states, trends in chemical reactivity, anomalous behaviour of first elements. An ideal body, which emits and absorbs all frequencies, chemistry notes class 11 cbse pdf download calleda black body.
P r incipal vbse number n: What are the properties of benzene? Second law of Thermodynamics brief introduction. So, due to the screening effect, the net positive charge experienced by theelectron from the nucleus is lowered and is known clas effective nuclear charge.
For chemistry formulas visit – https: To specify an orbital only three quantum numbers are required whileto specify an electron all four quantum numbers are required. InAvogadro proposed that equal volumes of gases at the same temperature and pressure should contain equal number of molecules.

There are a set of four quantum numbers which specifythe energy, size, shape and orientation of an orbital. He proved that the simplest aromatic compound having six carbon atoms is Benzene. The mole is the amount of substance of a system which contains as many elementary entities as there are atoms in 0.

Due to the presence of electrons in theinner shells, the electron in the outer shell will not experience the full positivecharge on chemistrt nucleus. Matters exist in three physical states viz.
Radial nodes occur when the probability chemistry notes class 11 cbse pdf download of wave functionfor the electron is zero on a spherical surface of a particular radius. It successfullydescribes the motion of macroscopic particles but fails in the case ofmicroscopic particles.
The value of the charge on an electron is These fields are perpendicular to each other and both areperpendicular to the direction of propagation of the wave. Summary of the chapter for class 11 Chemistry are available in PDF format for free download.

The uncertainty is indicated by writing the certain digits and the last uncertain digit.
A mixture may be homogeneous or heterogeneous. But, if otherwise, the terminal zeros are not significant if there is no decimal point.
