How do we read and understand the periodic tables of chemical elements?

Periodic Table of Elements (Periodic Table of Elements is one of the most important tools in chemistry, which forms all known chemical elements in tables according to atomic sequences (i.e. protons), electronic decomposers and similar chemical properties. The curriculum is compulsory for both junior and senior high school students and for scientific staff.

1. Periodicity and ethnicity (Peroods and Groups)

The periodic tables are designed to be extremely logical and are divided mainly into rows and columns:

Periodic (line): Tables with cross-references called cycles (Perood) totalling 7 cycle. The same-cycle elements have the same quantity of electronic layer (shell layer). The number of atomic extra-electronics of elements is increasing gradually from the left to the right, and the nature of the elements is also characterized by a pattern of transition from metallic to non-metallic.
Group (Leave): The column in the table is called Group, which is 18 years old. Family. The same elements of the race have the same amount of electronics at their outermost (priced electronic) level, which means that they display very similar chemical properties in their chemical reactions. For example, no. 1 All ethnic groups (alkalin metals) are very active and highly susceptible to electronic loss; The 18th (recent gases) is fully fledged and extremely inactivated.

Classification of elements and blocks

In our interactive periodic tables, elements are divided into different categories by different colours (blocks):

Alkaline metal & Alkaline earth metal: They are very lively metals at the leftmost side of the table (except hydrogen).
Transitional metals: Central blocks of the table, including common metals such as iron, copper, gold, silver, etc., are usually hard and have high melting points.
Non-metal and halogens: At the top right of the table (except hydrogen), it contains carbon, nitrogen, oxygen and live halogens (e.g. fluorine, chlorine) essential for life.
Rare gases: The top right column is extremely stable in chemical properties and hardly reacts to other elements.
The gills and the gills: For layout and beauty purposes, they are usually moved separately to two rows at the bottom of the table, which are internal transition metals, most of which are radioactive.

3. What are the parameters on the cards?

Click on any element of the above periodic table to see its detailed attribute card:

Atoms (Atomic Number): The only number determining the identity of the elements represents the number of protons in the atomic core.
Atom mass (Atomic Mass): The average mass of protons and neutrons is summarised, reflecting the weight of the elements.
Electronic release: The distribution of electrons in different energy levels (s, p, d, f) determines the chemical bonding capacity of the element.
ELECHROONGAVIVITY: Atoms are capable of attracting electrons in molecules. Non-metal Etherness is high (e.g. highest fluorine) and metal Etherness is low.

With this tool you can readily pass the fast-tracking element of Chinese name, English name, symbol spelling or atomic sequence, as a strong assistant for chemical operations and research!
