How many electrons go on the 2nd energy level?
How many electrons go on the 2nd energy level?
eight electrons
Regardless of its shape, each orbital can hold a maximum of two electrons. Energy level I has just one orbital, so two electrons will fill this energy level. Energy level II has four orbitals, so it takes eight electrons to fill this energy level.
Where is the second energy level of an atom?
The first energy level is closest to the nucleus. The second energy level is a little farther away than the first. The third is a little farther away than the second, and so on. Each energy level can accommodate or “hold” a different number of electrons before additional electrons begin to go into the next level.
What is the maximum number of orbitals on the 2nd main energy level?
| Orbitals and Electron Capacity of the First Four Principle Energy Levels | ||
|---|---|---|
| Principle energy level (n) | Type of sublevel | Maximum number of electrons (2n2) |
| 2 | s | 8 |
| p | ||
| 3 | s | 18 |
How do you find the energy level of an electron?
1 Answer
- E=−13.6n2 where the energy is in electron volts.
- n is the principle quantum number.
- So for an electron in n=1 :
- E=−13.6eV.
- To convert to joules you can x this by 1.6×10−19.
How many orbitals are in the energy level?
There are n2 orbitals for each energy level. For n = 1, there is 12 or one orbital. For n = 2, there are 22 or four orbitals. For n = 3 there are nine orbitals, for n = 4 there are 16 orbitals, for n = 5 there are 52 = 25 orbitals, and so on.
How do you find the number of orbitals in an energy level?
The number of orbitals in a shell is the square of the principal quantum number: 12 = 1, 22 = 4, 32 = 9. There is one orbital in an s subshell (l = 0), three orbitals in a p subshell (l = 1), and five orbitals in a d subshell (l = 2). The number of orbitals in a subshell is therefore 2(l) + 1.
How many electrons can the second shell hold?
8 electrons
The first shell (closest to the nucleus) can hold two electrons. The second shell can hold 8 electrons. The third shell can hold 32 electrons.
What is the energy of the 2nd energy level of a hydrogen atom?
-3.4 eV
If it is in the second energy level, it must have -3.4 eV of energy. An electron in a hydrogen atom cannot have -9 eV, -8 eV or any other value in between….Energy Levels of Electrons.
| Energy Level | Energy |
|---|---|
| 1 | -13.6 eV |
| 2 | -3.4 eV |
| 3 | -1.51 eV |
| 4 | -.85 eV |
How do you find the energy level of an atom?
The energy levels are built up from the level closest to the nucleus outward. This process of filling in the electrons from the first, lowest energy level to the second, slightly higher energy level to the third, even higher energy level is called filling the electrons in by the Aufbau Principle.
What is the maximum number of orbitals in the second energy level?
The second energy level will thus have a total of 4 orbitals. These orbitals will be distributed on two subshells, the s-subshell and the p-subshell.
