Answer 1

Atomic Structure of Calcium

The atomic structure of calcium consists of a nucleus at the center, which contains protons and neutrons, surrounded by electron shells. Calcium has an atomic number of 20, which means it has 20 protons in its nucleus. The atomic mass of calcium is approximately 40.08 atomic mass units (u).

The electron configuration of calcium can be represented as 1s2 2s2 2p6 3s2 3p6 4s2. This configuration indicates that calcium has two electrons in the 1s orbital, two electrons in the 2s orbital, six electrons in the 2p orbital, two electrons in the 3s orbital, and six electrons in the 3p orbital. The outermost electron shell, also known as the valence shell, is the 4s orbital, which contains two electrons.

The electron configuration of calcium can be further represented using the noble gas notation. Calcium's electron configuration can be abbreviated as [Ar] 4s2, where [Ar] represents the electron configuration of the noble gas argon (1s2 2s2 2p6 3s2 3p6).

The atomic structure of calcium can be summarized as follows: - Atomic number: 20 - Atomic mass: 40.08 u - Electron configuration: 1s2 2s2 2p6 3s2 3p6 4s2 or [Ar] 4s2
