Tips for Studying the Periodic Method of Chemical Factors
In high school you may have studied the periodic method of chemical elements for the science major. So when you are sitting in high school, you must be familiar with the chemical periodic table. Some students think that learning chemistry is one of the less enjoyable subjects because there are various types of formulas and it is necessary to memorize the chemical elements in it.
Apart from that, there are also students who think that chemistry is a fun subject. Now for those of you who are proven to not like learning chemistry, you can start learning to like learning such things by understanding various types of chemical factors in a periodic order.
Understand the Periodic Table of Chemistry
Before you get to know how to learn how to learn the periodic method of chemical elements, you should first get to know the chemical periodic table. From the periodic table is a table with chemical factors arranged according to atomic number. Such an ordered atomic number can contain the number of protons, the electron configuration and the chemical properties of the chemical elements of such a thing.
So in the chemical periodic table it will be divided into 4 blocks, namely the s, p, d, and f blocks. In one row from the left shows the properties of metals, although from the right shows the properties of non-metals.
Methods of Understanding the Chemical Periodic Table
After you understand what the periodic table is, then you must also know how the system understands it, as follows;
Read the Chemical Periodic Table from Top Left to Bottom Right
The chemical periodic table is organized by the various types of elements according to their atomic number. The more to the right and down, of course the atomic number will be higher. The atomic number is the number of protons that these elements have, and the more to the right the mass number of each atom will increase.
So you should understand the weight of an element even if you only pay attention to its location on the periodic table. The more to the right and down, the atomic mass of the element will increase because it is calculated by the number of protons and neutrons in each atom of this factor. The number will continue to increase because the number of protons will increase. Although electrons have no effect on the number of atomic weights.
Understand Chemical Elements
Next you must understand the most important chemical elements first. It should be noted that each of these factors contains 1 more proton than the atoms on the left-hand side of the periodic table. To be able to recognize, you can pay attention to the atomic numbers arranged from left to right.
These factors are then separated into three groups on the periodic table. For example, the first row shows hydrogen which has atomic number 1 and helium has atomic number 2. It can be concluded that these two factors are located at the left and right ends of the periodic table because they are in different classifications.
Recognize the Classification of Atoms with the Same Physical Properties
The next tip you should recognize is the classification of atoms that have the same external properties in the periodic table. The periodic table displays vertical columns, but in some cases these categories are characterized by the same color. These colors will help you to identify elements that have similar physical and chemical properties.
That way it will be easier for you to predict the reaction of the chemical elements of each particular category with the same number of electrons. Almost all of these chemical elements only belong to one group, apart from hydrogen which can be classified as halogens or alkali metals. On the periodic table of chemistry hydrogen will be in two groups and you have to understand these things.
Observation of Free Space in Table
Next it is recommended to always look at the free space in the table. The formation of factors into classifications and groups can establish the same physical and chemical properties. This way it is certainly easier to understand each factor reacting.
If the chemical elements are added, then the classification will be more difficult and this creates a blank space on the periodic table of chemistry. Suppose the first 3 rows have blank spaces because the functions for transition metals appear on the periodic table. Located at atomic number 21, then there are elements 57 to 71 which are rare earth elements. Not only that, but the soil factor is shown the largest on the right component below the periodic table.
Observe Each Timeline
Surely you already know that in this periodic table there is a time period and it is a must see. Each factor at one time period must have the same number of atomic orbitals and the next can be traversed by electrons. The number of orbitals can be adjusted according to the number of time periods on the periodic table which shows 7 rows and means 7 time periods.
For example, at a time factor of 1 it has 1 orbital. Explain that the 7-period element also has 7 orbitals.
Distinguish Between Metals, Semi Metals, and Non Metal
Studying chemistry, you also need to know the difference between metals, semi-metals, and non-metals. By distinguishing these things, it is possible to find the metal factor on the right of the table even though the non-metallic factor is on the left. For the classification of semi-metals, it is between metals and non-metals.
Closing
The periodic method of chemical elements is studied when you are in high school and of course things like that are not easy. Moreover, some students do not like learning chemistry. You don't need to worry, because some of the tips above can help you understand the periodic table and chemical factors.
