Cleaning up that snake-like house is comparable to a damn bud

The reason is that at the beginning, many people couldn't memorize the high holes, and people made this song in order to memorize the periodic table of chemical elements, so that everyone can remember the dry memories in Qizhong, and at the same time, it can also stimulate students' interest and potential in the subject of chemistry.
-
Because it can make students memorize better, the periodic table of chemical elements is more varied, and it is interesting to make a song, and it can strengthen memory.
-
The main purpose is to memorize the elements in the periodic table, remember the position of the elements, characteristics, quality, use, and so on.
-
The periodic table of chemical elements rolls or the knowledge that must be mastered in the chemistry discipline of the town, and the periodic table of chemical elements in the form of songs can allow us to better remember this knowledge in the songs.
-
Make it easy for everyone to remember and catchy to read.

The periodic table of chemistry is as follows:
Hydrogen (H), Helium (He), Lithium (Li), Beryllium (Be), Boron (B), Carbon (C), Nitrogen (N), Oxygen (O), Fluorine (F), Neon (Ne), Sodium (Na), Magnesium (Mg), Aluminum (Al), Silicon (Si), Sulfur (S), Chlorine (Cl), Argon (Ar), Potassium (K), Calcium (Ca).
Origin of the chemical element:
The origin of the idea of elements is very early, the ancient Babylonians and ancient Egyptians once regarded water (and later air and earth) as the main elements of the world, forming the three-element theory. The ancient Indians had four major doctrines, and the ancient Chinese had the Five Elements Doctrine.
The doctrine of the elements, that is, the doctrine of the elements as the simplest constituent parts of all real objects in nature, has arisen since time immemorial. However, in ancient times, the modern notion of the elements as a concrete form of matter did not exist.
Whether in the ancient philosophy of our country, or in the ancient philosophy of India or the West, the element is regarded as an abstract, a manifestation of the primitive spirit, or the basic nature of matter.
In the same period, from left to right, the number of electrons in the outer shell of the element is the same, the number of electrons in the outermost shell increases sequentially, and the radius of the atom decreases (except for group zero elements). The ability to lose electrons is gradually weakened, the ability to gain electrons is gradually increased, the metallicity is gradually weakened, and the non-metallic ability is gradually enhanced. The highest positive oxidation number of an element 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, except for the O and F elements in the second period).

2" is comparable to being tired of covering words (this teacher said that it is so prepared!) I'm too tired to cover the words) 3" touched the aluminum (female) good news her. >>>More
I'm a liberal arts major, so I'm only going to carry a column of alkali metals. Leave the milky shop (hydrogen, lithium, sodium, potassium, rubidium, cesium, francium).
