Topic: Periodic TableSummaryThe Periodic Table is an important Chemical visualization tool. It is shown below....
Understanding the Periodic TableThe Periodic Table organizes the (known) Chemical Elements in a way that highlights and illustrates the recurring -- the periodic -- trends in the properties. Each block -- each of those colored rectangles with a number and 1 to 3 letters in it -- in the periodic table represents a chemical element. The number in each block is the Atomic Number of that chemical element. The 1, 2 or 3 character letters in each block (ex: H, Au, In, and Uut) is the Chemical Symbol of that chemical element. The different color borders, of the blocks, represent some kind of trend or property. (It is meant to group those chemical elements together, to illustrate that they are somewhat similar.) Alkali MetalsThe (known) Alkali Metals are in the far left column. Specifically, they are: H, Li, Na, K, Rb, Cs, and Fr. Theoretically, the next Alkali metal would have an Atomic Number of 119. Such a Chemical Element does not have a name yet (although it would be easy to guess), and AFAIK has not been observed (either occuring naturally or having been synthetically created). Alkaline MetalsThe (known) Alkaline Metals (also called Alkaline Earth Metals) are in the column, to the right of the far left column -- the column to the right of the Alkali Metals Specifically, they are: Be, Mg, Ca, Sr, Ba, and Ra. Theoretically, the next Alkali metal would have an Atomic Number of 120. Such a Chemical Element does not have a name yet (although it would be easy to guess), and AFAIK has not been observed (either occuring naturally or having been synthetically created). Lanthanoid SeriesThe Lanthanoid Series consists of the Chemical Elements from Atomic Number 57 to 71. Specifically, they are: La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, and Lu. So namely....
Various names are used to name parts of this table. The ones I am aware of are listed following this. Actinoid SeriesThe Actinoid Series consists of the Chemical Elements from Atomic Number 89 to 103. Specifically, they are: Ac, Th, Pa, U, Np, Pu, Am, Cm, Bk, Cf, Es, Fm, Md, No, and Lr. So namely....
Rare Earth MetalsThe Rare Earth Metals (also sometimes called the Rare Earth Elements and sometimes abbreviated to REE) are Chemical Elements in the Lanthanoid Series, plus Sc and Y. So Namely....
