Calcium has a larger atomic radius than magnesium and a smaller atomic radius than potassium. This trend is due to the increase in number of protons and electrons as you move across the period on the periodic table from magnesium to calcium to potassium.
It has only two.They are zero and +2.
Magnesium's period number is 3. It is found in period 3 of the periodic table.
Mg
Calcium has a larger atomic radius than magnesium because it is located further down in the periodic table, resulting in an increased number of electron shells. However, potassium, being in the same group as calcium but further down, has a larger atomic radius than both calcium and magnesium. Thus, the order of atomic radii from smallest to largest is magnesium, calcium, and then potassium.
Magnesium has 25 protons
Silver or Gray.
magnesiums atomic number is 12 and has atomic mass of 24.3050 its element symbol is Mg melting point is 923 Kelvins or 650 C and was discovered in 1755 by Joseph Black of England, and was isolated by Sir Humphrey Davy in 1808. it is a solid element and used for old fashion flash photography missiles, airplanes, flares, and pyrotechnics.
Magnesium is a metal.It is a solid.
Well... I think its Magnesium Sulphur CozMg-MagnesiumS-SulphurSo I Just Added the Both Together!
this elemnt has an atomic number that is double the atomic number of silicon?
the answer is that it is called a atomic number.
