The electronic configuration of calcium is 2, 8, 8, 2 and the fourth energy level has 2 electrons.
Calcium atoms have 8 electrons in the second energy level. However, they are not the valence electrons. The outermost electrons in a calcium atom in the ground state are 2 4s electrons. So calcium atoms in the ground state have 2 valence electrons in the fourth energy level.
There are 8 electrons in the third energy level of a calcium atom.
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.
A calcium atom has two valence electrons.
calcium forms Ca+2 ion having 18 electrons which are equal to the electrons of noble gas Argon.

A calcium atom has 4 energy levels. The first energy level can hold up to 2 electrons, the second can hold up to 8 electrons, the third up to 8 electrons, and the fourth up to 2 electrons based on the electronic configuration of calcium, which is 2-8-8-2.
A calcium atom has two valence electrons.
Calcium, as an element, has 20 electrons. But when becomes an ion, it loses two electrons, becoming Ca+2. Therefore, as an ion, calcium has only 18 electrons.18
Calcium has twenty electrons in each atom.
Calcium has 2 valence electrons. Valence electrons are the electrons in the outermost energy level of an atom and are involved in forming chemical bonds with other atoms.
There are 20 electrons in a calcium atom.
A calcium atom tends to lose two electrons. This is because calcium has two electrons in its outermost shell (the fourth period of the periodic table), and it typically seeks to achieve a stable electron configuration by losing these two valence electrons. As a result, calcium commonly forms a +2 cation (Ca²⁺) in chemical reactions.
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.
A neutral atom of calcium has 20 electrons
