The rules of the periodic table of chemical elements!

I am hydrogen, I am the lightest, rockets rely on me to transport satellites;

I am helium, I am a rogue, I am the best at gaining and losing electrons;

I am Lithium has a low density and will bubble up when it comes into contact with water and acid;

I am beryllium, a swindler, although it is a metal that is difficult to ionize;

I am boron, black and silver, talking about electrons I am very poor;

I am carbon, react slowly, and can form chains and rings;

I am nitrogen, I am flame retardant, and hydrogenation can synthesize ammonia;

< p>I am oxygen, don’t think about it, you will feel panic if you leave me;

I am fluorine, the most vicious, just grab an electron and be satisfied;

I am neon, not bad either, When electrified, red light is emitted;

I am sodium, I have a strong temper, and I get angry when I encounter acid or water;

I am magnesium, I love beauty the most, and I shoot fireworks in photography;

p>

I am aluminum, bathe in concentrated sulfuric acid at room temperature;

I am silicon, black and gray in color, and I am piled with information components;

I am phosphorus , harmful to people, my name is on the highly toxic list;

I am sulfur, with a long history, best at precipitating metals;

I am chlorine, yellow-green in color, I grab metal electrons Go;

I am argon, with poor activity, I will emit the neon purple light;

I am potassium, add fire, and superoxide will take charge;

I am calcium, body love, bones and teeth are all there with me;

I am titanium, transition comes, I will cover the space shuttle;

I am chromium, hexachromium, alcohol comes here Turn green;

I am manganese, with many valence states, and the heptaoxide explodes violently;

I am iron, with many uses, stainless steel calls me "Master";

I am copper, purple in color, brown and red when nitric acid gas is added;

I am arsenic, dark in color, the trivalent element takes away your soul;

I am bromine, volatile and smelly, liquid If it is not gold, I will show you;

I am rubidium, an alkali metal, and potassium is not as good as firework dipped in water;

I am iodine, a sublimation smoke, and I encounter blue dots of starch;

I am cesium, golden yellow, it will explode if it enters water and the container will break;

I am tungsten, with high temperature, other metals will tremble early;

I am gold, very stable, if thrown into Water regia is invisible;

I am mercury, which is highly toxic, and I am the only liquid metal;

I am uranium, after enrichment, I am the best at making atomic bombs;

I am gallium, which melts easily and has a high boiling point and is difficult to evaporate;

I am indium, which is as soft as gold. Please be careful with slight radiation;

I am thallium, which can cause hair loss and is famous for poisoning. Look at Tsinghua University;

I am germanium, which can be used as a crystal lattice, and the infrared window can be used as a shell;

I am selenium, which can nourish the human body and there is a mystery in the oral solution;

I am lead, I can store electricity, and I am also in the bullet.

Extended information:

The periodic table of elements has 7 periods and 16 groups. Each horizontal row is called a period, and each column is called a family (group VIII contains three columns). These 7 cycles can be divided into short cycles (1, 2, 3) and long cycles (4, 5, 6, 7). There are 16 clans in ***, and each column from left to right counts as one clan (except clan VIII). For example: hydrogen belongs to group I A elements, while helium belongs to group 0 elements.

The position of an element in the periodic table not only reflects the atomic structure of the element, but also shows the gradient of the element's properties and the intrinsic relationship between the elements. It constitutes a complete system and is known as one of the important milestones in the development of chemistry.

In the same period, from left to right, the number of electron shells outside the element's core is the same, the number of electrons in the outermost shell increases successively, and the atomic radius decreases (except for group zero elements). The ability to lose electrons gradually weakens, the ability to gain electrons gradually increases, the metallicity gradually weakens, and the non-metallic property gradually increases.

The highest positive oxidation number of an element increases from left to right (except those without positive valence), and the lowest negative oxidation number increases from left to right (except for the first period, except for O and F elements in the second period) )
