How is the periodic table divided? How to read the periodic table from 113 to 118

The last few elements in the periodic table (elements 113 to 118) often begin with Uu. In fact, this is just a temporary naming rule called the IUPAC element system nomenclature. Next, let's take a closer look at how the periodic table is divided and how to read the periodic table 113 to 118. I hope it will be helpful to you.

How to divide the periodic table

The periodic table of chemical elements is divided into s zone, p zone, d zone, ds zone, and f zone, as follows:

1. The s region includes all elements of the first and second main groups.

2. The p zone includes elements from the third to seventh main groups plus group zero.

3. The d block includes elements from the third to seventh subgroups (except lanthanides and actinides) plus elements from the eighth group.

4. The ds region includes elements of the first and second subgroups.

5. The f-block includes lanthanides and actinides.

How to read the periodic table 113 to 118

The pronunciations of elements 113 to 118 in the periodic table are: "nǐ", "fū", "mò", "lì", "tián", "ào", etc.

No. 113, abbreviated as Nh in English, and its Chinese name is "鉨". (The simplified Chinese version cannot be typed out for the time being) The Chinese pronunciation is "nǐ".

No. 114, abbreviated as Fl in English, is called "鈇" in Chinese and pronounced "fū" in Chinese.

No. 115, abbreviated as Mc in English, is called "镆" in Chinese and pronounced "mò" in Chinese.

No. 116, abbreviated as Lv in English, and its Chinese name is "鉝". Its Chinese pronunciation is "lì".

No. 117, abbreviated as Ts in English, is called "Shitian" in Chinese. (There is a field next to the character "石"). The Chinese pronunciation is "tián".

No. 118, abbreviated as Og in English, is pronounced as “ào” in Chinese.

The last few elements in the periodic table (elements 113 to 118) often begin with Uu. In fact, this is just a temporary naming rule called the IUPAC element system nomenclature.

In this nomenclature, undiscovered elements and discovered but not yet formally named elements are given a temporary Western name and a substitute element symbol, using Latin numerals to name them according to the atomic number of the element.

How many rows are there in the periodic table?

The periodic table has 7 rows, each row is called a period. The elements in the same period have the same number of electron shells, and the atomic number increases from left to right. The period number is the number of electron shells that the elements in the period have. The first period is the shortest, with only two elements. The second and third periods have 8 elements each, which are called short periods. Other periods are called long periods.

From left to right in the same period, the number of electron shells outside the nucleus of the elements is the same, the number of electrons in the outermost shell increases successively, and the atomic radius decreases (except for the elements in Group 0). The ability to lose electrons gradually weakens, the ability to gain electrons gradually increases, the metallic properties gradually weaken, and the non-metallic properties gradually increase. The highest positive oxidation number of the elements increases from left to right (except for those without positive valence), and the lowest negative oxidation number increases from left to right (except for the first period, and the O and F elements in the second period).
