Contoh Soal Dan Pembahasan Konfigurasi Elektron from ojonyerah.my.id

The electron configuration of Calcium, with an atomic number of 20, is 1s2 2s2p6 3s2p6d10 4s2. This means that it has a total of 20 electrons distributed across its different energy shells. To understand the electron configuration of Calcium, it is important to first understand the concept of energy shells. Electrons in an atom occupy different energy levels or shells. The electrons in the innermost shell, closest to the nucleus, have the lowest energy while the electrons in the outermost shell have the highest energy. In Calcium, the first and second shells are completely filled with 2 and 8 electrons respectively. The third shell has a total of 8 electrons, out of which 2 occupy the 3s orbital and 6 occupy the 3p orbital. The fourth shell, which is also the outermost shell, has 2 electrons in the 4s orbital. The electron configuration of an atom plays a crucial role in determining its properties such as its reactivity, ionization energy, and electronegativity. Calcium is a highly reactive metal that readily forms ions by losing its two valence electrons. It is also an essential element for living organisms and is involved in various biological processes such as muscle contraction and nerve function. In conclusion, the electron configuration of Calcium with an atomic number of 20 is 1s2 2s2p6 3s2p6d10 4s2. This arrangement of electrons determines the chemical and physical properties of the element which makes it a vital element in various fields.
