Hydrogen is particularly notable for its diverse bonding behaviors. It most commonly forms covalent bonds, but it can also lose its single electron in an aqueous solution, leaving behind a bare proton with tremendous polarizing power. [86] Consequently, this proton can attach itself to the lone electron pair of an oxygen atom in a water molecule, laying the foundation for acid-base chemistry. [87] Moreover, a hydrogen atom in a molecule can form a second, albeit weaker, bond with an atom or group of atoms in another molecule. As Cressey explains, such bonding, "helps give snowflakes their hexagonal symmetry, binds DNA into a double helix; shapes the three-dimensional forms of proteins; and even raises water's boiling point high enough to make a decent cup of tea."

[131] Some consider metalloids distinct from both metals and nonmetals, while others classify them as nonmetals. [132] Some categorize certain metalloids as metals (e.g., arsenic and antimony due to their similarities to heavy metals). [133] [n 22] This article includes metalloids for comparative purposes [n 23] and due to their relatively low densities, high electronegativity, and chemical behavior. [127] Types of nonmetals and metals, their average electronegativity values, [74] [n 24] and electronegativity distributions arbitrarily divided into 0.5 spans (for the first 102 elements). For the types of nonmetals, there is a progression from less electronegative to more electronegative. A similar progression occurs for the types of metals. The transition metal values exclude those of the noble metals. Chemically, metalloids generally behave like (weak) nonmetals. Among the nonmetallic elements they tend to have the lowest ionization energies, electron affinities, and electronegativity values, and are relatively weak oxidizing agents. Additionally, they tend to form alloys when combined with metals.
