1 Answer

Answer :

The number of electrons in an atom is a unique number. The structure of which gives an idea of the properties of atoms. According to the laws of quantum mechanics, a certain number of electrons in an angle are arranged in different orbitals of different energy levels and sub-energy levels of that atom. This arrangement of electrons in different orbitals of atoms is called electron configuration of atoms. The electron configuration of an atom follows a number of general rules. The rules are as follows: (a) Pauli's Exclusion Principle ( b) Aufbau Principle ( c) Hund's Rule

(4) less soluble in blood than nitrogen at high pressure Explanation: Deep-sea divers have their oxygen supply mixed with helium in order to avoid the toxic nature of oxygen under extreme pressures. The Helium atom is much smaller than the Nitrogen molecule, has a smaller electron cloud and is less polarizable. It, therefore is less soluble in blood than nitrogen and prevents the formation of nitrogen bubbles in blood which blocks blood flow as the diver comes to the surface of the sea from underwater.
