One common chemistry assignment is to name or even memorize the first 20 elements and their symbols. The elements are ordered in theperiodic tableaccording to increasingatomic number. This is also the number ofprotonsin each atom. These are the first 20 elements, listed in order: ...
Calcium, abbreviated as Ca on the periodic table, is a chemical element with the atomic number 20. It is a metallic element that belongs to Group 2 (or Group IIA) of the periodic table, which is also known as the alkaline earth metals. Calcium is a chemical element that is essential fo...
Located right above the Englishname for each element, the largest letters represent itschemical abbreviation. The largest number is the element’satomic number. Other information in the box includes the element’s electron configuration, electronegativity, oxidation states, and its first ionization energy...
(LANL). With these elements, the atomic weight of the longest-lived isotope gets listed on the periodic table, according to the International Union of Pure and Applied Chemistry (IUPAC). These atomic weights should be considered provisional, since a new isotope with a longer half-life (how ...
