- Guide. Each element header has its name, atomic number, atomic symbol, and color code to indicate the group it belongs to. As an example, Hydrogen is green, so it belongs to the group “other nonmetals.”
- Hydrogen. Symbol: H. Atomic Weight: 1.008. Description: Hydrogen is an explosive gas and also the lightest element. Where It’s Used: Hydrogen makes up about 90 percent of the universe’s atoms.
- Helium. Symbol: He. Atomic Weight: 4.002602(2) Description: Helium is an inert gas and the second-lightest element. Where It’s Used: Helium gas is commonly known to be lighter than air, which leads to its use in weather and party balloons.
- Lithium. Symbol: Li. Atomic Weight: 6.94. Description: Under standard conditions, Lithium is the lightest metal and is soft and reactive. Where It’s Used: Lithium is known most commonly to be used in batteries.
Nov 3, 2023 · Over 99% of a human cell is made up of just five elements: carbon, hydrogen, oxygen, nitrogen, and phosphorus. That same elemental mix exists, with minor variations, in every other living thing on Earth.
May 17, 2014 · Here is a list of elements of the periodic table, their atomic numbers, and element symbols. The list is ordered by increasing atomic number, which is the number of protons in an atom of that element. Each element has a symbol, which is a one- or two-letter abbreviation of its name.
Like the periodic table, the list below organizes the elements by the number of protons in their atoms; it can also be organized by other properties, such as atomic weight, density, and electronegativity.
