Chemical bonding is a fundamental concept that explains how atoms combine to form compounds. There are several types of bonds, each with distinct properties and behaviors. Ionic bonds form when electrons are transferred from one atom to another, resulting in the formation of positively and negatively charged ions. These ions are held together by electrostatic forces. Covalent bonds occur when atoms share pairs of electrons, leading to the formation of molecules. Metallic bonds, found in metals, involve a 'sea' of delocalized electrons surrounding positive metal ions. Each type of bond influences the physical properties of the substance. For example, ionic compounds typically have high melting and boiling points and conduct electricity when molten or dissolved in water. Covalent compounds can have varying physical states and usually do not conduct electricity. Metals are characterized by their malleability, ductility, and electrical conductivity. Which type of bond is responsible for…
The “octet rule” in chemistry helps predict the types of bonds thatatoms will form. In general, an atom will be most stable if it fills itsouter shell of 8 electrons. Atoms with fewer than 4 valence electronstend to donate electrons and those with more than 4 valence electronstend to accept additional electrons; those with exactly 4 can do both.Using this rule, determine what category each of the followingelements falls into: N, S, C, P, O, H, Ca, Fe, and Mg. (You will needto work out the valence of the atoms.)
