10 Class- Periodic Classification of Elements

Periodic Classification of Elements In year of 1800 about 30 elements were known but at present we know about 114 elements. All these elements have different properties. So to study about these elements easily, scientists start searching some patterns in the properties to arrange these elements. Early Attempts in the Classification of Elements                                                                    This …

10 Class- Carbon and its Compounds

Carbon and Its Compounds Allotropes of Carbon – Fulleren-Diamond-Graphite ·             Instead of gaining and loosing electrons, carbon shares its 4-electrons with another element or carbon to form molecule. ·             Covalent bonds are formed as a result of sharing of electrons. Example- H2, O2, N2. Covalent compounds have low melting point and boiling point due to …

10 Class- Metals and Non-Metals

Metals and Non-Metals Metals             Metals are the solid materials which are typically hard, malleable, ductile and conduct heat and electricity, and also posses metallic lusture. Example- Iron, Gold, Aluminium, Silver, Copper etc. Non-metals                     Nonmetals are chemical elements which lacks metallic properties. Non metals are either solids or gases except Bromine (Br2), which occurs …
