Chemical Bond-An Introduction

 
        

            CHEMICAL BOND- AN INTRODUCTION 

Octet:-  Eight electrons in the outermost shell of an atom is said to form an octet. 

Duplet:- Two electrons in the outermost shell of an atom just like helium constitute a duplet. 

Q.1. why chemical reaction takes place? 

All elements want to achieve a stable configuration to their nearest noble gas. This leads to chemical reaction. 

Q.2. what types of way an element follows to achieve a stable configuration during chemical combination? 

The following ways are follows by an element to achieve a stable configuration during chemical combination:- 

1. By transfer of valence electrons from one atom to another. 

2. By sharing of valence electrons between two combining atoms. 

 

Chemical bonds:- The attractive force which holds together two atoms, two molecules, two ions or a combination of these is known as a chemical bond. 

Q.3. How many types of bonds are? 

There are two types of bonds are:- 

1. electrovalent bond 

2. covalent bond

Working of the heart

                           WORKING OF HEART   Blood from different parts of the body comes to right atrium, when it expands. Blood is brought from upper part of the body through superior vena cava and from lower part of the body through inferior vena cava.  When right atrium contracts, the blood goes to right ventricle. The atrioventricular aperture is closed by a valve after blood transfer. Valves prevent backflow of blood when the atria or ventricle contracts.    When the right ventricle contracts, blood forced out to the lungs for oxygenation through pulmonary artery, guarded by another valve. In lungs the exchange of gases takes place, blood give off carbon dioxide and takes in oxygen from lungs. Pulmonary vein brings oxygenated blood from lungs to the left atrium, as it relaxes. When the left atrium contract, the blood is transferred to left ventricle, which expands. The aperture be...

Response And Coordination In Plants

                       RESPONSE AND COORDINATION IN PLANTS  Plants movements  Tropic movement:-  The movements of organism in the direction of stimulus or away from stimulus are known as tropic movement or tropism.  It is positive if directed towards the source of stimulus and negative if directed away from stimulus.  Different types of tropic movements:-  Phototropism:- The tropic response of organism to light is called phototropism. If a young green plant takes light from one direction only, it bends towards the light source. So, the stem said to be positively phototropic.  Geotropism:- The tropic response of organism to gravity s called geotropism. If a growing region of plant placed horizontally, the stems tips grow away from pull of gravity while the root grows in direction of gravity. The stem is negatively geotropic and the root is said to be positively geotropic.  ...

A Genius Dmitri Ivanovich Mendeleev

                                           DMITRI IVANOVICH MENDELEEV         Dmitri Ivanovich Mendeleev was born in Tobolsk (Siberia), on 8 February 1934. After his early education, he joined university due to effort of his aged mother. He received a master degree in chemistry in 1856 and doctoral degree in 1865. He was appointed professor of general chemistry in 1867, at university of St. Petersburg. In 1869 he proposed a famous “periodic law” and constructed a periodic table of elements. In this table, he placed certain elements at specific places in accordance with their properties. He also predicted properties of some undiscovered elements.                 Mendeleev was a versatile genius. He was interested in many areas of science. He worked a lot on natural resources too. In 1890, he res...
