The number of covalent bonds an atom can form is called the valence of the atom. What are the characteristics of covalent bonds? We can represent the two individual hydrogen atoms as follows: In contrast, when two hydrogen atoms get close enough together to share their electrons, they can be represented as follows: By sharing their valence electrons, both hydrogen atoms now have two electrons in their respective valence shells. Beryllium makes two bonds (it is the only element in group 2 to make covalent compounds). There are three types of carbon atoms: sp, sp2, and sp3. (example CH4 - One carbon atom has combined with 4 hydrogen atoms , which can only form one bond each ). In each case, the sum of the number of bonds and the number of lone pairs is 4, which is equivalent to eight (octet) electrons. Phosphorus forms two chlorides PCl3 and PCl5. Thus, boron commonly forms three bonds, BH 3start text, end text, start subscript, 3, end subscript, with a total of six electrons in the outermost shell. General physical properties that can be explained by the covalent bonding model include boiling and melting points, electrical conductivity, bond strength, and bond length. The third bond that bromine can form with chlorine is a metallic bond. It is a strong acid due to the formed hydrogen bonds in the dissolved state. Since it has 4 valence electrons, it needs 4 more to electrons to fill its outer energy level. to the bond; it can therefore form single bonds with four neighbouring atoms. H forms only one bond because it needs only two electrons. But since hydrogen wants a complete shell, it can have 2 covalent bonds with 2 electrons. Carbon with four unpaired valence electrons forms four bonds in its allotropic forms* and typically in compounds.
