Chalcogens
Group 6A elements, known for their similarities with group 5A, including oxygen and sulfur.
Diatomic Molecules
Molecules composed of two atoms, such as O2 and N2, which are gases and nonmetals.
Polyatomic Molecules
Molecules composed of more than two atoms, like P4 and S8, which are solids and nonmetals.
Metalloids
Elements with properties between metals and nonmetals, such as arsenic and selenium.
Network Covalent Elements
Elements with covalent bonds forming a continuous network, like antimony and tellurium.
Synthetic Elements
Man-made elements, highly radioactive with short half-lives, such as Moscovium and Livermorium.
Electrical Conductivity
The ability of an element to conduct electricity, increasing as elements become more metallic.
Allotropes
Different structural forms of the same element, like ozone and orthorhombic sulfur.
Ozone
A bluish, pungent-smelling allotrope of oxygen, part of the ozone layer, reacting with UV light.
Orthorhombic Sulfur
The most stable form of sulfur, consisting of eight sulfur atoms in a cyclic structure.
Amorphous
A form of matter with atoms arranged randomly, lacking a defined shape, like amorphous tellurium.
Crystalline
A form of matter with atoms arranged in a repeating pattern, like hexagonal crystalline tellurium.
Electronegativity
A measure of an atom's ability to attract electrons, decreasing down group 6A.
Ionization Energy
The energy required to remove an electron from an atom, decreasing down group 6A.
Atomic Size
The size of an atom, increasing down group 6A due to additional electron shells.
