Mercury is a chemical element represented by the symbol (Hg), belonging to the twelfth group of the periodic table, called zinc-based, transition color of the silver metal, the only liquid metal under standard conditions of pressure and temperature. Mercury has an atomic number of 80, an atomic weight of 200.59, a melting point of 0.838, 87 ° C and a boiling point of 356.9 ° C. Natural mercury consists of seven different isotopes. As Hindus and ancient Chinese know, they are traceable: Found in the Egyptian tomb of 1500 BC. In China, India, and Tibet, it is widely believed that it can heal fractures, prolong life and stay healthy. The Greeks used creams like the Romans in cosmetics. Chemists believe they are the first to form all other minerals and can be produced by modifying the amount and quality of sulfur in mercury. chemistry analysis
Well known in ancient China and Hinduism, it was discovered in Egyptian tombs 3,500 years ago, pointing out that mercury is not useless, but comes in the form of hydrogen sulfide. Mercury (HgS), it should be noted that Spain and Italy have about half of the mercury content.

It is a very rare element of the earth’s crust representing only 0.08 ppm, mainly in cinnabar, the sulfide of mercury, a red pigment called samba.
It is a relatively low thermal conductor because most metals form excellent thermal conductors.
It is generally forbidden to use this product in airplanes because it mixes easily with the usual aluminum, destroying the oxide layer that prevents the oxidation of aluminum and prevents corrosion.
Although it often shows an equal number of oxidations (+ 1, + 2), it has an equal number of oxidation (+4).
He and his various compounds are highly toxic and should be treated with caution. Please follow special leak cleaning instructions to avoid exposure to toxicity. When heating.
It reacts with oxygen in the air when it is heated to form mercury oxide, which decomposes when heated to higher temperatures.

This is an example post, originally published as part of Blogging University. Enroll in one of our ten programs, and start your blog right.

You’re going to publish a post today. Don’t worry about how your blog looks. Don’t worry if you haven’t given it a name yet, or you’re feeling overwhelmed. Just click the “New Post” button, and tell us why you’re here.

Why do this?

• Because it gives new readers context. What are you about? Why should they read your blog?
• Because it will help you focus you own ideas about your blog and what you’d like to do with it.

The post can be short or long, a personal intro to your life or a bloggy mission statement, a manifesto for the future or a simple outline of your the types of things you hope to publish.

To help you get started, here are a few questions:

• Why are you blogging publicly, rather than keeping a personal journal?
• What topics do you think you’ll write about?
• Who would you love to connect with via your blog?
• If you blog successfully throughout the next year, what would you hope to have accomplished?

You’re not locked into any of this; one of the wonderful things about blogs is how they constantly evolve as we learn, grow, and interact with one another — but it’s good to know where and why you started, and articulating your goals may just give you a few other post ideas.

Can’t think how to get started? Just write the first thing that pops into your head. Anne Lamott, author of a book on writing we love, says that you need to give yourself permission to write a “crappy first draft”. Anne makes a great point — just start writing, and worry about editing it later.

When you’re ready to publish, give your post three to five tags that describe your blog’s focus — writing, photography, fiction, parenting, food, cars, movies, sports, whatever. These tags will help others who care about your topics find you in the Reader. Make sure one of the tags is “zerotohero,” so other new bloggers can find you, too.
