What are 5 examples of compounds?
Examples of Compounds:Water – Formula: H2O = Hydrogen2 + Oxygen. … Hydrogen Peroxide – Formula: H2O2 = Hydrogen2 + Oxygen2 … Salt – Formula: NaCl = Sodium + Chlorine. … Baking Soda – Formula: NaHCO3 = Sodium + Hydrogen + Carbon + Oxygen3 … Octane – Formula: C8H18 = Carbon8 + Hydrogen18
What is the most essential element to life?
CarbonCarbon is the most important element to life. Without this element, life as we know it would not exist. As you will see, carbon is the central element in compounds necessary for life.
What is the 5th element of nature?
The fifth element on top of earth, air, fire, and water, is space or aether. It was hard for people to believe that the stars and everything else in space were made of the other elements, so space was considered as a fifth element.
What are the 10 examples of elements?
Pure Element ExamplesHydrogen (H) – nonmetal.Helium (He) – nonmetal.Oxygen (O) – nonmetal.Neon (Ne) – nonmetal.Nitrogen (N) – nonmetal.Carbon (C) – reactive nonmetal.Silicon (Si) – metalloid.Magnesium (Mg) – alkaline earth metal.More items…
What’s the most useful element?
carbonLife demands a huge variety of molecules, with chains and rings and branches and cages—tricks that iron rarely attempts. And so we are left with carbon, the most versatile, most adaptable, most useful element of all. Carbon is the element of life.
What are the essential elements that affect life?
Scientists believe that about 25 of the known elements are essential to life. Just four of these – carbon (C), oxygen (O), hydrogen (H) and nitrogen (N) – make up about 96% of the human body.
What is compound and give 5 examples?

What is an element give 5 examples?
Answer. an element is a substance that cannot be split into simpler substances by a chemical means . for example – hydrogen, oxygen, nitrogen, carbon, iron, aluminium, copper, silver and gold some example of elements.
What are the two essential elements that affect life?
The two essential elements that affect life are carbon and oxygen. Most of the carbon is found in the form of carbon dioxide in the atmosphere.
What is the most expensive element on earth?
franciumThe most expensive natural element is francium. Although francium occurs naturally, it decays so quickly that it cannot be collected for use. Only a few atoms of francium have been produced commercially, so if you wanted to produce 100 grams of francium, you could expect to pay a few billion U.S. dollars for it.
What element do we use everyday?
ELEMENTUSES1)AluminumA light metal used in making airplanes, buildings, pots & pans, etc.2)BromineUsed in photography, medicines, insecticides, etc.3)CalciumA soft, metallic chemical element found in limestone, marble, chalk, etc.4)CarbonFound in coal, oil gas, living things, & inks24 more rows
What elements can you find at home?
A number of elements exist in a pure form in nature such as oxygen and nitrogen (in air), gold, silver, carbon (graphite and diamonds), and sulfur. A few very familar elements include: iron in steel, copper in pipes in your house or the copper coating on pennies, and aluminum popcans.
What is the 5th element of earth?
The fifth element refers to what was known as the aether, a special unknown substance that permeated the celestial sphere and was purer than any of the four terrestrial elements. The notion of a fifth element was broached by Plato and later written about by Aristotle, but neither philosopher used the term.
What are the 5 most important elements?
1. Note that most living matter consists primarily of the so-called bulk elements: oxygen, carbon, hydrogen, nitrogen, and sulfur—the building blocks of the compounds that constitute our organs and muscles. These five elements also constitute the bulk of our diet; tens of grams per day are required for humans.
What are the 7 elements of life?
There are seven of them, namely:Element #1: Physical health.Element #2: Mental health.Element #3: Family health.Element #4: Financial health.Element #5: Vocational health.Element #6: Social health.Element #7: Spiritual health.
