A chemical element is a pure substance consisting of only one type of atom, identified by its atomic number, that cannot be broken down into simpler substances through chemical reactions.
There are currently 118 confirmed chemical elements on the periodic table, including 94 naturally occurring elements and 24 synthetic elements created in laboratories through nuclear reactions.
Natural elements exist in nature and can be found on Earth or in space, while synthetic elements are artificially created in laboratories through nuclear reactions and are typically radioactive.
The periodic table is an organized chart arranging all chemical elements by increasing atomic number, grouped by similar chemical properties and electron configurations into rows called periods and columns called groups.
Hydrogen is the most abundant element, comprising about 75% of the universe’s mass, followed by helium at approximately 23%, with all other elements making up the remaining 2%.
Gallium is a metallic element with a melting point of only 29.76°C (85.57°F), meaning it liquefies from body heat when held, though it’s non-toxic and safe to touch briefly.
Gold is chemically inert and non-toxic, making it safe to consume. Edible gold leaf is used to decorate luxury desserts, chocolates, and drinks, passing harmlessly through the digestive system.
Ytterby, a small village in Sweden, inspired the names of four elements: yttrium, ytterbium, terbium, and erbium, discovered in minerals from its nearby quarry during the 18th and 19th centuries.
Osmium has a density of 22.59 grams per cubic centimeter, making it twice as dense as lead. A basketball-sized sphere of osmium would weigh approximately 1,000 pounds.
Mercury and bromine are the only elements that exist as liquids under standard conditions, with mercury being a silvery metal and bromine a reddish-brown, corrosive non-metal halogen.
