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 does calcium have in the second energy level?
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.
Why calcium turns to red in the flame test?
Because, due to the absorption of heat energy by the calcium atom in the flame. The electrons in the atom get promoted to a higher energy level, and exist in an unstable excited state. As they are unstable and prefer to be at their normal ground state, the extra energy that the electrons absorbed to be promoted in the first place is emitted in the form of a photon, light. The light emitted from the electrons of the calcium atoms will be at a specific wavelength, which is the red light you see emitted from the flame.

What is the principal quantum number for the outermost electrons in a bromine atom in the ground state?
The electronic configuration of Bromine in its ground state is: 1s2 2s2p6 3s2p6d10 4s2p5. Therefore the principal quantum number for the outermost electrons in a Bromine atom is 4.
How many sublevels are completely occupied in the second principal energy level of a sodium atom in the ground state?
The 2s and 2p sublevels in the second principal energy level are completely occupied in the ground state of a sodium atom.
Where are the electrons that possess the least amount of energy located in a calcium atom in the ground state?
An electron in the third shell has more energy than an electron in the second shell.
How many electrons does calcium have in the second energy level?
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.
Can electrons lose energy at ground state explain?
No. At ground state, the electrons are at their lowest energy.

What is the total number of completely filled principal energy levels in an atom of argon in the ground state?
In Neon atom the 10 electrons are present in two principal energy levels, 2 in ist and 8 in 2nd level.
What is the total number of occupied sublevels in the third principal energy level of a zinc atom in the ground state?
Zinc atoms contain 30 electrons in the electron configuration 1s22s22p63s23p63d104s2. There are a total of 7 sublevels that contain electrons in an atom of zinc in the ground state.
What is the principal quantum number for the outermost electrons in a bromine atom in the ground state?
The electronic configuration of Bromine in its ground state is: 1s2 2s2p6 3s2p6d10 4s2p5. Therefore the principal quantum number for the outermost electrons in a Bromine atom is 4.
How many electrons are there in the neutral atom which has the ground state outer electron configuration of 4s2?
Calcium has the electron configuration [Ar]4s2; the neutral atom of calcium has 20 electrons.
How many electrons are in the energy levels of carbon?
In its ground state, carbon does not have any electrons in the third energy level.
How many electrons are in the third energy level of helium?
Helium has only one energy level with two electrons. It does not have electrons in other energy levels in its ground state.
How many sublevels are completely occupied in the second principal energy level of a sodium atom in the ground state?
The 2s and 2p sublevels in the second principal energy level are completely occupied in the ground state of a sodium atom.
Where are the electrons that possess the least amount of energy located in a calcium atom in the ground state?
An electron in the third shell has more energy than an electron in the second shell.
How many energy levels are occupied in an atom of carbon?
You shouldn't use terms like "outer level", because they're confusing. It could potentially mean at least two things, specified more precisely below. The highest occupied energy level of a ground state neutral carbon atom, the 2p level, has two electrons. The number of electrons in a ground state neutral carbon atom that have a principal quantum number of 2 (the highest associated with any electrons in such an atom) is four.
