Study Notes
- Nonmetals are located on the right side of the periodic table, including groups 13-18 and families such as noble gases, halogens, some unclassified nonmetals, and metalloids.
- Nonmetals have high ionization energy, preventing them from easily losing electrons.
- They have high electronegativity, forming ionic or polar covalent compounds when reacting with metals.
- Nonmetals have low boiling points.
- They are poor conductors of heat and electricity (insulators).
- There are 23 total nonmetals on the periodic table.
- Metalloids, a group between metals and nonmetals, are sometimes considered nonmetals or weak nonmetals.
- Metalloids possess properties of both metals and nonmetals, acting as semiconductors.
- Reactive nonmetals, or halogens, are highly corrosive and reactive, forming ionic bonds with metals of low ionization energy and electronegativity.
- Noble gases are located to the right of reactive nonmetals and are nonreactive due to their fully filled outer electron shells.
- Nonmetals generally show opposite characteristics to metals.
- Periodic table is organized by atomic number, valence electrons, and electron orbitals, leading to a trend of electronegativity increasing and atomic radii decreasing.
