Valency is crucial in determining the ratios of atoms in chemical formulas. The valency of oxygen (2) and hydrogen (1) determines the H2O formula for water. 7 Valence Another term for valency Valency The combining power of an element, especially as measured by the number of hydrogen atoms it...
Question: What is a polar molecule? Types of Bonds: There are two main types of strong bonds that occur between molecules, covalent and ionic. Ionic bonds occur when one atom donates electrons to another. Covalent bonds occur when two atoms share electrons. ...
semiconductors are silicon and germanium. The silicon and germanium require lower energy to break their covalent bonds in the crystal. This is the main reason for using these two semiconductors most commonly. Silicon requires 1.1 eV for breaking any covalent bond in its crystal and germanium ...
