40 diagram of covalent bond
One coordinate bond in which both electrons are donated from the N atom to the B atom 4. One coordinate bond in which both electrons are donated from the O atom to the C atom 5. No coordinate bonds (1 mark for each correct dot and cross diagram; 1 mark for correct identification of the coordinate bond or the lack of coordinate bond) 3.2.2. The energy band diagram of a p-type Semiconductor is shown below: A large number of holes or vacant space in the covalent bond is created in the crystal with the addition of the trivalent impurity. A small or minute quantity of free electrons is also available in the conduction band. Coordinate Covalent Bonds. A coordinate bond (also called a dative covalent bond) is a covalent bond (a shared pair of electrons) in which both electrons come from the same atom. A covalent bond is formed by two atoms sharing a pair of electrons. The atoms are held together because the electron pair is attracted by both of the nuclei. Diagram of covalent bond...
