20 chemical elements jingle.

Mandarin: hydrogen, helium, lithium, beryllium, boron, carbon, nitrogen, oxygen, neon, sodium, magnesium, aluminum, silicon, phosphorus, sulfur, chlorine, argon, potassium and calcium.

Memory formula: Dear Li, let go and raise happiness. (Hydrogen, helium, lithium, beryllium, boron, carbon, nitrogen, fluorine, neon) That beautiful woman Guilin, beef should be added with calcium. (sodium, magnesium, aluminum, silicon, phosphorus, sulfur, chlorine, argon, potassium and calcium).

Metal active sequence table

Metal active sequence table is a memory method of 20 element symbols, and it is also the basis for convenient subsequent application. The table arranges 20 kinds of metal elements in a certain order, which is convenient for memory and identification. Among them, potassium, calcium, sodium, magnesium, aluminum, zinc, iron, tin, lead, hydrogen, copper, mercury, silver, platinum, gold and other elements have their own unique symbols and naming methods.

This classification method is not only helpful for memory and recognition, but also can be easily applied to other fields, such as chemistry and biology.

universal method

The memory formula of element symbols is a memory method, which helps to remember by comparing the symbols of elements. Among them, the general method is a commonly used method.

For example, elemental tungsten can be combined with tungsten wires in incandescent lamps, and elemental sulfur can be combined with running water in winding streams. Common element symbols are compared and memorized in alphabetical order. This method can help us remember elements faster and improve the efficiency of memory.

Raise a daughter to stick a pot cover, which one has no food?

This is the formula of the top 10 element in the earth's crust, in which the daughter is connected to the pot cover, and which one has no food? It refers to which family has no green vegetables. Oxygen, silicon, aluminum, iron, calcium, sodium, potassium, magnesium, hydrogen and titanium refer to element symbols. This formula means that besides oxygen, silicon, aluminum, iron and calcium, sodium, potassium, magnesium, hydrogen and titanium, there are other elements that have not been mentioned.

The appearance of this formula makes us have a deeper understanding of the characteristics of elements and also makes us understand the importance of diet. In modern society, people pay more and more attention to healthy diet, and green vegetables are one of the essential vegetables. So pay attention to diet, eat more vegetables and stay healthy.

The first letter should be uppercase followed by lowercase letters.

When memorizing 20 element symbols, the first letter should be capitalized and the following letters should be lowercase. This is because the symbol of the element is the abbreviation of the element name, and the initial letter is the initial letter of the element name. For example, carbon c is the name of carbon element, copper Cu is the name of copper element,

Nitrogen N is the name of nitrogen, phosphorus P is the name of phosphorus, sulfur S is the name of sulfur, oxygen is the name of oxygen, aluminum Al is the name of aluminum, iron A is the name of iron, copper Ba is the name of copper, barium Ba is the name of tungsten W, Ag is the name of silver, zinc Z is the name of zinc, iodine I is the name of iodine, and potassium K is the name of potassium.

Br Br H is the name of hydrogen, hydrogen U is the name of uranium, Fe, Fe, Na, Na, Mg, Ca and Ca, Hg and Ag are the names of mercury, Au is the name of gold, and Sn, Sn, Sb and Sb are the symbols of elements. Memorizing these symbols can help us better understand and remember the names of elements and the meanings of symbols.
