The atomic number of calcium is 20. How many protons does it …
Calcium is a chemical element with atomic number 20 which means there are 20 protons in its nucleus. Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z. The total electrical charge of the nucleus is therefore +Ze, where e (elementary charge) … Meer weergeven Atomic mass of Calcium is 40.078 u. The atomic mass is the mass of an atom. The atomic mass or relative isotopic mass refers to the … Meer weergeven The atomic radius of Calcium atom is176pm(covalent radius). It must be noted, atoms lack a well-defined outer boundary.
