    • Paramagnetic: Those substances which are attracted by magnetic fields are called paramagnetic substances. Paramagnetic materials such as aluminum and air have permeability’s slightly greater than that of free space (for air μr =1.0000004).
    • Diamagnetic :Those substances which are repelled by magnetic fields are called diamagnetic  substances. A material that turns at a right angle to the field by producing a magnetic response opposite to the applied field is called diamagnetic material such as silver, copper, and carbon have permeability’s slightly less than free space

    The binary compounds of hydrogen with metals and non-metals are called hydrides. The hydrides are of three types:
    (i) Ionic or salt like hydrides: These hydrides are formed by the highly electropositive elements of Group 1 and Group 2 except Be and Mg. They are formed by the transfer of electrons from the metals to the hydrogen atom. As such they are ionic compounds (Li+H-) and thus behave like salts. For example, LiH, NaH, CaH2.
    (ii) Molecular or covalent hydrides: These are formed by elements having higher electronegativity than hydrogen i.e. by the p-block elements. These are formed by sharing of electrons between the element and hydrogen atom. As such they are covalent or molecular compounds.
    (iii) Metallic or interstitial hydrides: The d-block and f-block elements combine with hydrogen to form non-stoichiometric interstitial hydrides. Hydrogen is in the atomic state which occupies interstitial holes in close-packed metal structures. The composition of an interstitial hydride changes with temperature and pressure. These hydrides give out hydrogen easily and hence act as strong reducing agents.

    H2O + F2 ---> HF + HOF oxidation number of F in F2 = 0 oxidation number of F in HF = -1 oxidation number of F in HOF = +1 Here,we see oxidation number of FE decreases from zero to -1(HF) and increase from +1(HOF). This shows that F2 is both reduced as well as oxidised. hence, it is a redox reaction and more specifically , it is a disproportionation redox reaction.

    Zeolites are crystalline solids structures made of silicon, aluminum and oxygen that form a framework with cavities and channels inside where cations, water and/or small molecules may reside. They are often also referred to as molecular sieves. Many of them occur naturally as minerals, and are extensively mined in many parts of the world finding applications in industry and medicine.

    The octet rule is a chemical rule of thumb that reflects observation that atoms of main-group elements tend to combine in such a way that each atom has eight electrons in its valence shell, giving it the same electron configuration as a noble gas.
