Atomic Diagram Of Calcium. The element atomic number and name are listed in the upper left. Each orbital can hold no more than two electrons.
Calcium metal is used as a reducing agent in preparing other metals such as thorium and uranium. The atomic number is significant to know as it helps to know more about elements. 20 electrons occupy available electron shells rings.
For each electron shell atom diagram the element symbol is listed in the nucleus.
The electron shells are shown moving outward from the nucleus. 20 electrons occupy available electron shells rings. This means that there are two electrons in the 1s orbital and one electron in the higher energy 2s orbital. Well put six in the 2p orbital and then put the next two electrons in the 3s.
