They are often used in signs as they glow in bright colors when an electrical current is passed through them.Īlkali Metals - These elements have just 1 electron in the outer shell of their atom and are very reactive. It is also used in lighting, lasers, and cryogenic refrigeration. It is known for its characteristic bright orange-red glow when used in signs and advertising. This means they don't react much with other elements. Neon is a chemical element with atomic number 10 and is a noble gas. They are unique in that the outer shell of their atoms is full of electrons.

The periodic table of chemical elements, often called the periodic table, organizes all discovered chemical elements in rows (called periods) and columns (called groups) according to increasing atomic number. Noble Gases - Helium, neon, argon, krypton, xenon, and radon are all noble gases. The ‘What Element Am I’ quiz uses a range of questions to associate your personality traits with a particular element. Calcium, abbreviated as Ca on the periodic table, is a chemical element with the atomic number 20. Of these, only 94 are thought to naturally exist on Earth.Įlements are sometimes grouped together because they have similar properties. Depending on how carbon atoms fit together they can form diamond, coal, or graphite. ![]() They can also take different forms depending on how tightly the atoms are packed together. Depending on their temperature they can be solid, liquid, or gas. The content includes biology, chemistry, Earth/space. Silicon (Atomic number 14) is an important element in electronicsĮven though elements are all made from the same type of atoms, they can still come in different forms. The answer choices for each question will contain changes in one or more of those elements of writing.
