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...

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...

Respiration Notes For Class 10

RESPIRATION NOTES FOR CLASS 10 Respiration:- Respiration commonly involves the use of oxygen to break down carbohydrates and other organic molecules, giving usable energy, carbon dioxide and water in this process. Anaerobic respiration:- Partial oxidation of food in the absence of oxygen, resulting in release in some amount of energy is called anaerobic respiration. 1. How pyruvate is formed in anaerobic respiration? => Glucose has 6 carbon atoms joined to each other by covalent bond. Hydrogen and oxygen atoms are also attached to these carbon atoms. In anaerobic respirations of glucose; some of hydrogen atoms are removed and resulting in its oxidation. After a series of reaction the glucose get converted into two molecules of pyruvate, containing 3 atoms of carbon. This reaction also produces two molecules of ATP. Glycolysis:- The oxidation of glucose in a series of reactio...
