3. Group (periodic table) - Wikipedia

   en.wikipedia.org/wiki/Group_(periodic_table)

   In chemistry, a group (also known as a family) [1] is a column of elements in the periodic table of the chemical elements. There are 18 numbered groups in the periodic table; the 14 f-block columns, between groups 2 and 3, are not numbered.

4. List of chemical classifications - Wikipedia

   en.wikipedia.org/wiki/List_of_chemical...

   Chemical classification systems attempt to classify elements or compounds according to certain chemical functional or structural properties. Whereas the structural properties are largely intrinsic, functional properties and the derived classifications depend to a certain degree on the type of chemical interaction partners on which the function is exerted.

   Chemistry is the scientific study of the properties and behavior of matter. [1] It is a physical science within the natural sciences that studies the chemical elements that make up matter and compounds made of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during reactions with other substances.

7. List of chemistry mnemonics - Wikipedia

   en.wikipedia.org/wiki/List_of_chemistry_mnemonics

   A mnemonic is a memory aid used to improve long-term memory and make the process of consolidation easier. Many chemistry aspects, rules, names of compounds, sequences of elements, their reactivity, etc., can be easily and efficiently memorized with the help of mnemonics.

8. Periodic table - Wikipedia

   en.wikipedia.org/wiki/Periodic_table

   The chemical elements are what the periodic table classifies and organizes. Hydrogen is the element with atomic number 1; helium, atomic number 2; lithium, atomic number 3; and so on. Each of these names can be further abbreviated by a one- or two-letter chemical symbol; those for hydrogen, helium, and lithium are respectively H, He, and Li. [6]

9. Chemical species - Wikipedia

   en.wikipedia.org/wiki/Chemical_species

   The chemical species can be an atom, molecule, ion, or radical, with a specific chemical name and chemical formula. [ 2 ] In supramolecular chemistry , chemical species are structures created by forming or breaking bonds between molecules, such as hydrogen bonding , dipole-dipole bonds , etc. [ 3 ] These types of bonds can determine the ...
