How many electrons does calcium have and where are they located at?
The atomic number of calcium is 20 as it has 20 protons and 20 electrons, they are located outside the Nucleus in the orbits known as energy levels, and are commonly known as shells of the atom. in the first energy level there are 2 electrons, in the second energy level there are 8 electron, in the third energy level there are 8 electrons, and in the fourth energy level there are 2 electrons.
What is the electron arrangement for calcium?
The electron arrangement for calcium is 2,8,8,2. This means that calcium has 20 electrons arranged in four energy levels, with 2 electrons in the first energy level, 8 electrons in the second and third energy levels, and 2 electrons in the fourth energy level.
Can there be 20 electrons in the thrid energy level?
No. Maximum of 18 electrons is possible in third energy level.
Can there be more than 20 electrons in the third energy level?
no, up to 18 electrons only in the 3rd energy level.
What is the electron configuration for and atom of calcium?
The electron configuration for a calcium atom, which has an atomic number of 20, is 1s² 2s² 2p⁶ 3s². This notation indicates that calcium has two electrons in the first energy level (1s), eight in the second level (2s and 2p), and two in the third level (3s). The full configuration can also be abbreviated as [Ar] 4s², where [Ar] represents the electron configuration of argon, the preceding noble gas.
What is the highest occupied energy sublevel for Strontium?
Answer. 4sCa = Calcium Atomic number is 20, that means it has 20 proton and 20 electron.1s2,2s2,2p6,3s2,3p6,and 4s2, total of 20 electrons, therefore Highest occupied energy level of Ca is 4s
How many electrons are in the fourth level of a calcium atom?
There are 2 electrons in the fourth energy level of a calcium atom. Calcium has an atomic number of 20, which means it has 20 electrons distributed in different energy levels, with 2 electrons in the first energy level, 8 electrons in the second energy level, 8 electrons in the third energy level, and 2 electrons in the fourth energy level.
