Chemical elements are homophonic and funny

The homonym of chemical elements is funny as follows:

1. The first cycle: ammonia hydroxide-infringement.

2, the second cycle: boron, carbon and nitrogen oxyfluoride-carp skin holding carbon eggs to nourish fu milk.

3, the third cycle: sodium magnesium aluminum silicon phosphorus sulfur chlorine box-that beauty Guilin leaves green teeth.

4, the fourth cycle: potassium, calcium, vanadium and chromium-marry and change Kangtai. Iron Diamond, Nickel, Copper and Zinc Marry Germanium —— A New Marrier with Iron Gu Pinching Pain. Arsenic, selenium, Australia and nitrogen-angry shock.

5, the fifth cycle: riveting steel red fault-so tell you. Nail it-it's terrible. Ming Yin Fu Gang Xi Rui-Lao Ba Yin Ge Yin Xi Di. Tiao iodine-place fairy.

6, the sixth cycle: bell-colored shell blue river. Tungsten money-but seeing a crow attracts a goose. Platinum, mercury and lead-a white towel for him to hold. Needle puncture-you must not love winter.

7, the seventh cycle: spinning radium steel-lightning protection.

The importance of chemistry:

1. Ensure the survival of human beings and continuously improve their quality of life. For example, chemical fertilizers and pesticides are produced to increase grain output. Chemical synthesis of drugs is used to inhibit bacteria and viruses and protect human health. Using chemistry to develop new energy and new materials to improve human living conditions. Using chemistry to comprehensively apply natural resources and protect the environment to make human life better.

2. Chemistry is a practical subject, which, together with mathematics and physics, has become the basis for the rapid development of natural science. The core knowledge of chemistry has been applied to all areas of natural science, and chemistry is an important pillar of the powerful force to transform nature. At present, chemists use the viewpoint of chemistry to observe and think about social problems, and use chemical knowledge to analyze and solve social problems.

3. The intersection and infiltration of chemistry and other disciplines has produced many marginal disciplines, such as biochemistry, geochemistry, cosmochemistry, marine chemistry, atmospheric chemistry, etc., which has led to the rapid development of science and technology such as laser, geology and ocean, which have improved the measuring device of oxygen content in the air of biology, electronics, aerospace and junior high school chemistry experiments.

4. Cultivate the psychology of continuous progress, discovery, exploration and curiosity, stimulate human's desire to understand nature and enrich people's spiritual world.
