Elementary table formula junior high school jingle

Elementary table formula junior high school jingles are as follows:

1. The valence should be accurately recorded, namely univalent potassium sodium silver chloride, bivalent calcium barium magnesium zinc oxide, aluminum trisilicate tetraaluminum pentavalent phosphorus;

It is not difficult to talk about price changes. Iron, iron, carbon and sulfur are all complete, and copper and mercury are the most common.

Do not divide atomic groups, univalent ammonium hydroxide, bivalent sulfate carbonate and trivalent phosphate.

2. Monovalent iodine and hydrogen, as well as metal potassium, sodium, silver, bivalent barium oxide, calcium, magnesium, zinc, aluminum, silicon and silicon are all fixed;

Pay attention to the valence changes of chlorine and nitrogen, such as copper, mercury, gold, lead, iron, sulfur and phosphorus;

3. Fuwan is iodine negative; Silver monohydride and potassium sodium. Remember the negative two of oxygen first; Magnesium, calcium, barium and zinc were positive.

Positive three is aluminum positive silicon, and then change the valence. All metals are positive, and one or two copper makes two or three iron.

Manganese is 24 and 67; Remember carbon 24. Non-metallic negative body is uneven; Chlorine is negative, one is positive and the other is 57.

Nitrogen and phosphorus are negative three and positive five; Different phosphorus, three nitrogen, two four. Sulfur has negative two plus four six; Remember, it's cooked after use.

4. Potassium, sodium, silver and hydrogen are univalent, while calcium, magnesium, barium and zinc are bivalent;

Aluminum is n-trioxane and negative dioxane, and chlorine is the most common one.

Sulfur has negative two positive four six, positive two positive three iron changes;

Simple materials with positive one, two, two, copper, two, four, carbon and zero price will never change;

Other elements have valence changes, and they are counted after death.
