For reasons of space, [30] [31] the periodic table is commonly presented with the f-block elements cut out and positioned as a distinct part below the main body. [32] [30] [23] This reduces the number of element columns from 32 to 18. [30] Both forms represent the same periodic table. [6]

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.
This is a list of chemical elements and their atomic properties, ordered by atomic number (Z).. Since valence electrons are not clearly defined for the d-block and f-block elements, there not being a clear point at which further ionisation becomes unprofitable, a purely formal definition as number of electrons in the outermost shell has been used.
The most common values of atomicity for the first 30 elements in the periodic table are as follows: Atomic Number ... 21 Scandium (Sc) 1 22 Titanium (Ti) 1 23 ...
