We can find calcium as a non metal element. Atomic number of it is 20.
Yes, Calcium has an atomic number of 20 but its Atomic Mass is actually 40.078 and it is the 5th. most abundant element by mass in the Earth's crust.
20 electrons
It equals to 20. Mass number equals 40
Calcium has the atomic number 20 and is placed in the fourth period and the second group of the periodic table of Mendeleev.
The farther to the left and toward the bottom of the periodic table, the lower the electronegativity, and the larger the atomic radius. Calcium has a large atomic radius in comparison to elements in it's own period. What are you comparing calcium too? Calcium does have a large radius but not the largest, the largest is Cesium.

Calcium is a metal. It readily oxidizes in air. Because it makes up such a large part of the skeleton, about one-third of the mass of human body comes from calcium, after water has been removed.
