A: Magnesium, in its elemental form, has 12 protons and 12 electrons. The neutrons are a different matter. Magesium's average atomic mass is 24.305 atomic mass units, but no magnesium atom has exactly this mass.

An inner transition metal (ITM) is one of a group of chemical elements on the periodic table. They are normally shown in two rows below all the other elements. They include elements 57-71 (lanthanides) and 89-103 (actinides). The lanthanides are very similar, and the actinides are all radioactive.

- Remember that the mass number (a.k.a atomic mass)- is the number of PROTONS and NEUTRONS in the nucleus of the atoms of that element. - The periodic table gives us the atomic number of each element. For example, Hydrogen has the atomic number of 1 and Oxygen has the atomic number of 8.

How Are Elements Grouped in the Periodic Table? The classic Periodic Table organizes the chemical elements according to the number of protons that each has in its atomic nucleus.

The periodic table, also known as the periodic table of elements, is a tabular display of the chemical elements, which are arranged by atomic number, electron configuration, and recurring chemical properties. ... The seven rows of the table, called periods, generally have metals on the left and nonmetals on the right.

When Mendeleev arranged the elements in order of increasing atomic mass, the properties where repeated. Because the properties repeated themselves regularly, or periodically, on his chart, the system became known as the periodic table.

One can trace today's controversies over how the periodic table should look to the discovery of quantum mechanics and atomic numbers. Mendeleev ostensibly organized his table by increasing atomic weight, but he gave chemical properties a deciding vote.

Magnessium is a group 2 metal that forms cations with a stable noble gas electronic configuration when it loses its two valence electrons. Bromine forms a stable noble gas electronic configuration when it gains one electron. Thus we find magnesium as 2+ cation and bromine as a 1- anion in a 1:2 ratio in the compound.

Atomic mass is never an integer number for several reasons: The atomic mass reported on a periodic table is the weighted average of all the naturally occuring isotopes. Being an average it would be most unlikely to be a whole number. The mass of an individual atom in atomic mass units is the mass relative to carbon-12.

There are four main groups of elements in the periodic table: main group metals, non-metals, metalloids, and transition metals (See types of elements).

Periodic Table of the Elements. The periodic table (also known as the periodic table of elements) is organized so scientists can quickly discern the properties of individual elements such as their mass, electron number, electron configuration and their unique chemical properties.
