A compound is a pure substance that is formed by the combination of atoms of two or more elements by either transfer or by sharing of electrons. The atoms of the different elements in a compound are chemically combined in a fixed and constant proportion. If this proportion is di..

(KNO 2 ), carbon dioxide (CO 2 ) and carbon monoxide (CO). The properties of compounds are absolutely different from the properties of the elements that constitute the compound. For instance, hydrogen is combustible and oxygen is a supporter of combustion. But their product, wat..

The steps in writing Lewis structures of covalent compounds are as follows: of the molecule by placing the atoms of the combining elements properly. Usually an atom, which forms the largest number of bonds with other atoms is written as the central atom of the structure. For example in PC..

This balance consists of a beam and two scale pans (shown in figure below), the beam being balanced at its mid point on a knife-edge. The scale pans also hang on knife edges and rest on the base board. When the balance is not in use the beam rests on the beam support. A Laboratory Bala..

The electrostatic field of an ion is nondirectional.Each positive ion attracts several negative ions around it depending upon its size or radius and vice-versa ,resulting in a three dimensional solid aggregate called an ionic crystal in which oppositely charged ions alternate in regular,continuous..
