The smallest atom in the periodic table in terms of mass is hydrogen, which has only one proton and one electron. Hydrogen has no neutrons. The element has an atomic number of 1 and atomic weight of 1.00794, making it the smallest of all the elements.


An atomic number represents the amount of protons that an element consists of in its nucleus. It is the identifying number that is unique to one atom of the specific element.


The atomic number is the value given to the number of protons in the nucleus of an atom. This value is the same as the charge value of an atom.


A period on the periodic table is a horizontal grouping of elements running from the left to right of the table. Several trends are observed going from the left side of the periodic table to the right.


Co in the periodic table of elements is cobalt. Located in group nine, period four of the periodic table, this transition metal has an atomic number of 27 and an atomic weight of 58.9. It is a hard element that appears bluish-gray in color.


The Periodic Table offers basic information about each one of the known chemical elements. Each element has its own box in the table, and these boxes include the element's atomic number, atomic weight and chemical symbol. An element's position on the table indicates which elements share its basic pr


The atomic number indicates the number of protons present in the nucleus of an atom, which is used to uniquely identify the atom, as well as its chemical properties. The atomic number is denoted by the universal symbol "Z."


The periodic table classifies chemical elements by their similarities and properties. Each square in the periodic table shows an element's atomic number, its symbol, its name and its atomic weight, which is the number of protons and neutrons the element has.


The periodic table's name comes from the fact that it arranges the elements into repeating sets, otherwise known as "periods." These periods are defined by the covalence of an element, the number of electrons it has in its outermost shell and by other elemental attributes. This arrangement places el


The periodic table got its name from the way the elements are arranged in rows, which are called periods. The columns of the table are called groups, some of which have specific names, such as the noble gases and the halogens.
