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.
The principal quantum number for the outermost electrons in a Bromine atom in the ground state is?
The principal quantum number for the outermost electrons in a Bromine atom in the ground state is 4. This is because the outermost electrons of an atom are located in the highest energy level, and for Bromine (with 35 electrons), the outermost electrons are in the 4th energy level.
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?
In the ground state, a sodium atom in the second principal energy level has two sublevels completely occupied: the 2s and the 2p sublevels. The 2s sublevel can hold a maximum of 2 electrons, and the 2p sublevel can hold a maximum of 6 electrons.
Where are the electrons that possess the least amount of energy located in a calcium atom in the ground state?
The electrons with the least amount of energy in a calcium atom in the ground state are located in the innermost electron shell, closest to the nucleus. These electrons have lower energy levels as they are shielded by the outer electron shells.

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 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.
Why does calcium burn orange?
When calcium burns, the orange color is due to the excitation of electrons in the calcium atoms. The energy released as the electrons return to their ground state appears as light, in this case, the characteristic orange color. This phenomenon is similar to how fireworks emit colorful lights when certain materials are burned.
What is the total number of occupied sublevels in the third principal energy level of a zinc atom in the ground state?
The third principal energy level (n=3) has s, p, and d sublevels. In the ground state, the zinc atom has all the s, p, and d sublevels in the n=3 energy level occupied. Therefore, the total number of occupied sublevels in the third principal energy level of a zinc atom in the ground state is 3.
Can electrons lose energy at ground state explain?
Electrons at ground state have the lowest energy levels in an atom. They can lose energy by emitting a photon of light or by participating in a chemical reaction. This energy loss can cause the electron to move to a lower energy level or to be released from the atom altogether.
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.
