Write a note on the Covalent bond?

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 …

Why does Lithium show anomalous behavior in its group

Anomalous Behavior of Lithium in its group: Lithium being 1st member of the group 1 with the symbol Li and atomic number 3 and electronic configuration of 1s2 2s1 shows some differences from the rest of the members of its group. (i)  Melting and boiling point of Lithium are much higher than other members of its …

Trends in Chemical properties of elements in period 3

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 …

What is meant by ionization Energy – Digital Kemistry

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 …
