Concrete is composed of both ionic and covalent compounds. The main components of concrete, such as Portland cement, consist of ionic compounds formed from calcium, silicon, and aluminum oxide. The aggregates used in concrete, such as sand and gravel, are composed of covalent compounds like silica and quartz.
Cerium typically forms ionic bonds rather than covalent bonds. In its compounds, cerium usually forms the +3 oxidation state, where it loses three electrons to form ionic bonds with other elements.
Water (H2O) - formed by covalent bonds between hydrogen and oxygen atoms. Methane (CH4) - composed of covalent bonds between carbon and hydrogen atoms. Carbon dioxide (CO2) - consists of covalent bonds between carbon and oxygen atoms.
Phosphorus (P) typically forms 3 covalent bonds due to its electronic configuration of 5 valence electrons. This leads to the formation of compounds such as phosphorus trihydride (PH3) or phosphorus trichloride (PCl3).
The main types of chemical bonds are ionic bonds, covalent bonds, and metallic bonds. Ionic bonds form between a metal and a nonmetal through the transfer of electrons. Covalent bonds occur when atoms share electrons, typically between two nonmetals. Metallic bonds are found in metals and involve a sea of delocalized electrons surrounding positively charged metal cations.
The valency of nitrogen is 3 or 5. It can form three covalent bonds in compounds such as ammonia (NH3), or five covalent bonds in compounds such as nitrate (NO3-).
Boron is in group 3 and forms generally 3 covalent bonds. Because forming 3 bonds only gives boron a share of 6 electrons boron compounds are Lewis acids.

There are 6 covalent bonds in a molecule of cyclopropane - 3 carbon-carbon bonds and 3 carbon-hydrogen bonds.

Nitrogen can form three covalent bonds when it has no negative charge.
The element Arsenic would be expected to form 3 covalent bonds in order to obey the octet rule. As is a nonmetal in group 5A, and therefore has 5 valence electrons. In order to obey the octet rule, it needs to gain 3electrons. It can do this by forming 3 single covalent bonds.
