A cumulative compound DC motor is the one in which the series field aids the shunt field i.e. Characteristics of organic compounds. Covalent Nature: Carbon atoms form stable covalent bonds with one another. Because of the greater nuclear charge and smaller size, alkaline earth metals create compounds that are primarily ionic but less ionic than alkali metal compounds. Compounds - Compounds are chemical substances made up of two or more elements that are chemically bound together in a fixed ratio. 1. What are the five characteristics of ionic compounds? high melting and boiling points. A Compound is same throughout in properties and composition. A compound is formed as aresult of chemical reaction, between theconstituent elements. Characteristics of covalent compounds : 1. ii) Due to maximum catenation and tetravalency of carbon, they have tendency to form long open and . Therefore, covalent compounds are usually volatile liquids or gases. When the elements combine, some of their individual properties are lost, and the newly formed compound has new properties. The bases of a compound function both grammatically and semantically as a single word. Learn someth. 1(a), (b) and (c). A compound is made up of one or more atoms of the same or different elements. Combustibility . A compound is a homogeneous substance and the property through out the compound is same. Transmembrane diffusion is non-saturable and depends, on .

It exists as metal carbonates, hydrocarbons, and carbon dioxide gas in its combined state. Aromatic compounds play key roles in the biochemistry of all living things. A compound has a fixed melting point and boiling point. The law of constant composition can be used to distinguish between compounds and mixtures of elements: Compounds have a constant composition; mixtures do not. identical. Its properties are different from the elements that make it up. Different types of chemical bonds and their varying intensity are directly responsible for some of the physical properties of minerals such as hardness, melting and boiling points, solubility, and conductivity. Ionic compounds have high melting and boiling points, again due to strong forces of attraction between the ions. Prominent properties of ionic compounds are: Ionic Compound Properties 1. Atoms are the smallest units of matter that still retain the fundamental chemical properties of an element. Molecules are the simplest unit of a covalent compound, and molecules can be represented in many different ways.
