Write a note on the Covalent bond? ANSWER: COVALENT BOND: INTRODUCTION: G.N Lewis proposed that atoms could attain stable electronic configuration by sharing electrons between them. Covalent Bond Definition: The bond which is formed by the mutual sharing of electrons is called a covalent bond. REPRESENTATION OF COVALENT BOND: The shared pair of electrons are …

What is an Ionic bond? Ionic Bond Definition: In simple words, an ionic bond is a chemical bond which is formed due to the complete transfer of electrons from one atom to another atom. An ionic bond is also called an electrovalent bond. How is an ionic bond formed? Following are the conditions which are …

Trends in Chemical properties of elements in period 3 : Period 3 of the table consists of Sodium, Magnesium, Aluminum, Silicon, Phosphorus, Sulphur, Chlorine and Argon. They can be roughly divided into metals (Na, Mg and Al), metalloids (Si) and non-metals (P, S, Cl, and Ar), and therefore the elements within these groups tend to …

The energy required to remove an electron from an atom or ion, or its propensity to give up an electron, is measured by the ionisation energy or ionisation potential in chemistry and physics. The ground state of a chemical species is often where electron loss occurs. Ionization energy, also called ionisation energy, is the measure …

Electron Affinity Key points: Electron Affinity is the energy released when an electron is added to the outermost shell of an isolated, neutral gaseous atom. The electron affinity increases from left to right in a period. The electron affinity decreases down the group. Factors affecting Electron Affinity: The key factors that influence electron affinity are …
