What is the monovalent formula for potassium, sodium, silver and hydrogen?

Potassium, sodium, silver, hydrogen, positive bivalent, calcium, magnesium, barium, zinc, positive bivalent, fluorochlorobromo, iodine, negative bivalent, usually oxygen is negative bivalent, 12 copper, 23 iron, 3 aluminum, 4 silicon, 5 valent phosphorus, 246 sulfur, 24 carbon, elementalValencyis 0.

In any compound, the algebraic sum of positive and negative valencies is zero, where hydrogen is usually +1 and oxygen is usually -2. Metallic elements.

It usually has a positive valence and non-metallic elements usually has a negative valence. The valency of the elements in the element is zero, many elements have variable valency, and the same element can show different valencies in different compounds, such as FeO, the valency of iron in Fe2O3 is +2 and +3 respectively.

Introduction to valency :

Valence is the property of an element that manifests itself when one atom is atomized with other elements.

In general, the valence of valence is equal to the number of electrons gained and lost by each atom during compounding, that is, the number of electrons gained and lost when the element can reach a stable structure, which is often determined by the electronic configuration of the element, mainly the outermost electron configuration, and of course may also involve the sub-layers that the subouter shell can reach.

composed of substable structures.

The mantra for potassium, sodium, silver and hydrogen is "kuai na yin qiang pai".

The mantra is made up of the pronunciation of the chemical symbols for the elements potassium (k), sodium (na), silver (ag) and hydrogen (h). It can help to memorize the positive monovalent state of these elements in chemical reactions. Note that these elements may also have other valence states in different cases.

The chemical symbol for potassium (k) is derived from Latin"kalium", pronounced with"Fast"Similar.

The chemical symbol for sodium (Na) is derived from Latin"natrium", pronounced with"Take"Similar.

The chemical symbol for silver (ag) is derived from Latin"argentum", pronounced with"Silver"Similar.

The chemical symbol for hydrogen (H) is derived from Latin"hydrogenium", pronounced with"Hydrogen"Similar.

This mantra can help learners memorize the positive univalent state of these elements, which is convenient for application and memorization in chemistry learning.

Monovalent potassium, sodium, silver chloride, divalent oxygen, calcium, barium, magnesium, zinc, trialuminum, tetrasilicon, pentacarbon, phosphorus, di-iron, ditetracarbon, tri-nitrogen, 246 sulfur are complete, and copper and mercury bivalent are the most common. This is what our teachers teach

In junior high school, in fact, just look at the number of electrons of the atom, for example: 8 electrons, the first layer is: 2, and the second layer rows:

6 pcs. Our stable electron arrangement is that the first shell is:2 and the second shell:

8, 2 are missing, and 2 are stronger than others, which is -2 price. Similarly.

Monovalent potassium, sodium, silver chloride, divalent oxygen, calcium, barium, magnesium, zinc, there is no need to memorize, do more questions, naturally remember, and there is the periodic table, in the first few columns is the valence, and the negative ones are used to get the valence of the negative elements with -8.

I think the valency formula made up by our teacher is quite effective

The apparent negative valence of oxygen is minus two, and the valency of the elements in the element is zero.

Hydroxide OH negative monovalent ammonium NH4 is positive.

Carbonate CO3 negative bivalent Sulfate SO4 negative bivalent.

Nitrate NO3 is negative monovalent.

Metallic Substances:

Potassium, sodium, silver, hydrogen +1 valence.

Aluminum-iron +3 price [ferrous +2 price].

The rest +2 valence.

Negative valency of non-metallic substances:

Chlorochlorobromoiodine-1 valence.

Oxysulfur -2 valence.

Phosphorus and nitrogen -3 valence.

The positive valence of the rest of the non-metallic substances can be calculated by looking at the chemical formula

The active ingredient of household bleach is Naclo, in which the chemical valence of chlorine is [+1] Analysis: because the sum of the chemical formula is zero, that is: Na+Cl+O=0 1+Cl-2=0, so Cl is +1 valence.

Because it is annoying to keep track of the positive valency of non-metallic elements, it is good to calculate it yourself when the time comes

Sulfate -2 valence.

Carbonate -2 valence.

Nitrate -1 valence.

Ammonium +1 valence.

Hydroxide -1 valence.

If you don't know about the valency, you can ask me again
