The Periodic Table - Magnesium
Magnesium is an alkaline earth metal whereas helium is a noble gas. On the periodic table magnesium has an atomic nuer of 12, whereas helium has an atomic nuer of 2. When A helium balloon is lit it will not ch fire it will only burst and produce a very loud bang due to the gases escaping, Magnesium on the other hand, when lit, produces a very fierce bright white light.
The Alkaline Earth Metals (Group 2) - 2012
Elemental magnesium is the only alkaline earth metal that is produced on a large scale (about 5 × 10 5 tn per year). Its low density (1.74 g/cm 3 compared with 7.87 g/cm 3 for iron and 2.70 g/cm 3 for aluminum) makes it an important component of the lightweight metal alloys used in aircraft frames and aircraft and automobile engine parts ( Figure 21.13 "Magnesium Alloys Are Lightweight and

A custom-made ligand has unlocked barium’s organometallic chemistry, including the first molecular barium fluoride and the first molecule with a barium–tin bond. Molecular heavy alkaline earth metals such as calcium can replace expensive transition metal alysts in common transformations and make some unusual reactions happen .

Metals & Metal Forms | AMERICAN ELEMENTS
Alkaline metals are the Group 2 elements of the period table and consist of beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra). Because of their lower activity and affinity for their other neighbor on the periodic table, the transition metals, they have found many appliions and uses in alloys to produce lighter high strength metals.
