Both have two valence electrons had hence similar properties.
Calcium and Magnesium both belongs to second group.They both are Alkaline Earth Metals.Magnesium has 12 atomic number where as Calcium has 20 atomic number.
Dolomite is not an element but rather a mineral composed primarily of calcium carbonate and magnesium carbonate. Therefore, it does not have an atomic number like elements do. Instead, the atomic numbers of the elements in dolomite are 20 for calcium (Ca) and 12 for magnesium (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.
The atomic number of Magnesium is 12.
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.
The atomic number of magnesium is 12. The atomic number tells you the number of protons in the nucleus of the magnesium atom, which also corresponds to the number of electrons in a neutral magnesium atom.
The atomic number of calcium is 20.
The most common calcium isotope, calcium-40, has 20 neutrons.
Mg- Magnesium
