The periodic table of elements is a great way to visualize the elements and their symbols.
The element Hydrogen with the symbol H is a nonmetal. It is the most abundant element in the universe. Hydrogen combines with oxygen to form water. Water makes up approximately 71% of Earth's surface.
The element Helium has the symbol He and is a noble gas. It is a product of radioactive decay and can be found in the lithosphere where it is dug up.
Lithium has the symbol Li and is an alkali metal. It can be found in igneous rock and as a component of chloride salts.
Beryllium has the symbol Be and is an alkaline earth metal. It is found in igneous rock within the Earth's crust.
Boron has the symbol B and is a post-transition metal. It combines with oxygen to form a chemical known as borate. Boron is found in the sea and in sedimentary rocks.
Carbon has the symbol C and is a nonmetal. It is a component of organic compounds including sugars, starches, proteins, and fats. It is exhaled as carbon dioxide. It is found in the bodies of plants, animals and is a component of fossil fuels. A diamond is a chunk of carbon after it has been compressed over a long period of time.
Nitrogen has the symbol N and is an important nonmetallic element which can be found in proteins like enzymes and hormones. It is found in nucleic acids. The nitrogen cycle on Earth recycles nitrogen between living things and the environment. Approximately 78% of Earth's atmosphere is composed of nitrogen gas.
Oxygen has the symbol O. Twenty percent of the atmosphere is composed of oxygen gas. It is also the most abundant element in earth's crust. It is a component of water and many organic compounds. Plants release oxygen gas as a product of photosynthesis. Ozone, found in the ozone layer of the atmosphere, is composed of oxygen. The ozone layer protects Earth from harmful rays from the sun.
Fluorine is a halogen. Its symbol is F. Fluorine can be found in the Earth's crust in rocks and clay soils. It may sometimes be found in the air with dust particles.
Neon has the symbol Ne and is a noble gas. It is the fifth must abundant element in the universe. It is colorless, odorless, and inert. It is rare on Earth, but can be found in small trace amounts in the atmosphere and crust.
I have included an excellent link to an interactive periodic table so more research can be done on the elements found on Earth.
