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.
An atom of calcium in the Bohr model has four energy levels. These energy levels are designated by the quantum numbers n=1, 2, 3, and 4, corresponding to the first, second, third, and fourth energy levels, respectively.
A neutral atom of calcium has five energy levels that are partially or fully occupied. These energy levels are filled with electrons according to the Aufbau principle, with the first two levels (K and L) being fully filled while the remaining three levels (M, N, and O) are partially filled.
a sulfur atom has 3 energy levels. 2 on the first. 8 on the second and 6 on the third
Answer3 energy levels17 protons and electrons
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.
An atom of calcium in the Bohr model has four energy levels. These energy levels are designated by the quantum numbers n=1, 2, 3, and 4, corresponding to the first, second, third, and fourth energy levels, respectively.
two, i think recommend you check this answer not entirely sure
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.
A neutral atom of calcium has five energy levels that are partially or fully occupied. These energy levels are filled with electrons according to the Aufbau principle, with the first two levels (K and L) being fully filled while the remaining three levels (M, N, and O) are partially filled.
a sulfur atom has 3 energy levels. 2 on the first. 8 on the second and 6 on the third

There are 8 electrons in the third energy 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.
