electrostatic attractions

It is the force of attraction existing between the nucleons i.e., between two protons, or two neutrons, or a proton and a neutron. Nuclear force is a short range force and it is effective only when the nucleons are closely packed inside the nucleus. In a heavy atom the size of the atom i..

These types of forces occur in molecular solids which have polar molecules. A polar molecule has separate centres of positive and negative charges. These forces arise due to electrostatic attraction of the other molecule and vice-versa (The positive end of one molecule att..

The electrostatic force of attraction, which exists between the covalently bonded hydrogen atom of one molecule and the electronegative atom of the other molecule is known as hydrogen bon..

Electrovalent substances are made up of ions in the solid state. The oppositely charged ions are held together by strong electrostatic (coulombic) force of attraction. Due to these forces the ions cannot mov..

Ionic compounds have high melting and boiling points. A large amount of energy is required to break the crystal lattice, because the ions are held together by strong electrostatic forces of attraction. The variation in melting point depends upon the charges on the ions and ioni..

Covalent or metallic bonds, ionic bonds Chemical bonds between atoms in molecules such as H2, CH4, NH3, H2CCH2, N2, Cl2 Electrostatic attraction in salt crystals such as NaCl Inter-molecular forces in a solid and liquid Lewis dot structures - Shape of simple molecules ..

All molecules (polar and non-polar) exert a weak attraction upon the other, due to the electrostatic attraction of the electrons of one molecule to the nuclei of the other. These forces are known as van der Waals forces. They occur in all kinds of molecular solids inc..

Question: Name the fundamental force which holds the planets in their orbits around the sun. 1. Gravitational force of attraction 2. Electrostatic static force of attraction 3. Nuclear force of attraction 4. Electro static force of ..

Conclusion - The discovery of gravitation by Sir Isaac Newton, due to his observation of the falling apple, explained the movements of planets and satellites not only in our solar system but also in other systems as well. It explained why the Earth and other planets where spherical or nearly spheri..
