∙ 12y ago
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.

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.
How many electrons are the third energy level of a calcium atom?
There are 8 electrons in the third energy level of a calcium atom.
What is the total number of electrons in the second principal energy level of a calcium atom in the ground state?
The electron configuration of calcium is: 1s2 2s2 2p6 3s2 3p6 4s2 The "second principle energy level" refers in this case to the 2s and 2p orbitals, so it would be a total of 8 electrons.
How many electrons are in the second energy level of magnesium?
There are six electrons are in the second energy level of magneisum. A further two are on the first energy level and the last two are on the third energy level.
How many electrons are in the fourth level of a calcium atom?
The electronic configuration of calcium is 2, 8, 8, 2 and the fourth energy level has 2 electrons.

How many electrons are the third energy level of a calcium atom?
There are 8 electrons in the third energy level of a calcium atom.
What liquid non metal has the same energy level of calcium?
Calcium has electrons in the 4th energy level. The only liquid that has valence electrons in energy level 4 would be BROMINE.
What is the total number of electrons in the second principal energy level of a calcium atom in the ground state?
The electron configuration of calcium is: 1s2 2s2 2p6 3s2 3p6 4s2 The "second principle energy level" refers in this case to the 2s and 2p orbitals, so it would be a total of 8 electrons.
If an atom has 7 electrons how many electrons are located in the second energy level?
An atom with seven electrons will have five electrons in the second energy level.
Does calcium have three electrons that complete its valence shell?
The element calcium is in the fourth energy level and second group of the periodic table. This put it in the 's' orbital group with two valence electrons.
