Chemical properties of group 18 elements
WebDec 8, 2024 · The number of elements in a period is determined by the maximum number of electrons that may be accommodated in an atom’s various shells. Groups – Groups are the vertical columns in a periodic table. In the long form of the periodic table, there are 18 groups. The elements in a group do not have the same atomic number. WebThe Group 18 elements include Helium (He), Neon (Ne), Argon (Ar), Krypton (Kr), Xenon (Xe), and Radon (Rn). They are referred to as noble gases or inert gases.

WebApr 2, 2024 · All the elements of group 18 i.e. Helium (He), Neon (Ne), Argon (Ar), Krypton (Kr), Xenon (Xe), Radon (Rn), Organesson (Og) are non-metallic elements. The zero group is designated so because of the zero valence electrons that the elements of this group have. Group 18 is placed in the extreme right-hand side of the long periodic table.
WebThe number of valence electrons of an element can be determined by the periodic table group (vertical column) in which the element is categorized. In groups 1–12, the group number matches the number of valence electrons; in groups 13–18, the units digit of the group number matches the number of valence electrons.
