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 20 electrons arranged in four energy levels or rings around the nucleus.
In a neutral atom of calcium, there are 4 energy levels that are partially or fully occupied. Calcium has 20 electrons, distributed among the 4 energy levels with 2, 8, 8, and 2 electrons in each energy level, respectively.
There are 20 electrons in a calcium atom.
Calcium has 20 electrons
calcium has 20 neutrons and electrons
Calcium has 20 electrons in the neutral atom.
Calcium has two valence electrons.
Calcium (Ca) has 4 energy levels, corresponding to its electron configuration of 1s² 2s² 2p⁶ 3s² 3p⁶ 4s². The first energy level can hold 2 electrons, the second can hold 8, the third can hold 18, and the fourth can hold 2 in the case of calcium. Therefore, the distribution of electrons in these levels defines the four distinct energy levels for calcium.
Calcium is a non metal element. There are 20 electrons in a single atom.
