Electron shells
| Energy shell | Maximum number of electrons |
|---|---|
| First | 2 |
| Second | 8 |
| Third | 8 |
How many electrons fill the first energy level?
2 electrons
There are 2 electrons on the first energy level, 8 electrons on the second level, 8 electrons on the third energy level, and 1 on the fourth energy level. Explain that after the third energy level has 8 electrons, the next electron goes into the fourth level.
How many electrons fill the 2nd energy level or shell?
eight electrons
Energy level II has four orbitals, so it takes eight electrons to fill this energy level. Q: Energy level III can hold a maximum of 18 electrons.
How many electrons are in the first shell energy level 1?
The first shell, closest to the nucleus and with the lowest-energy electrons, is shell 1. This first shell has only one subshell (labeled 1s) and can hold a maximum of 2 electrons.
How many electrons can fit in the first energy shell?
What is the maximum amount of electrons you can fit on the first energy shell? Each shell can contain only a fixed number of electrons: The first shell can hold up to two electrons, the second shell can hold up to eight (2 + 6) electrons, the third shell can hold up to 18 (2 + 6 + 10) and so on. Why are there only 2 electrons in the first shell?
What is the formula for the number of electrons in a shell?
Each shell can contain only a fixed number of electrons: The first shell can hold up to two electrons, the second shell can hold up to eight (2 + 6) electrons, the third shell can hold up to 18 (2 + 6 + 10) and so on. The general formula is that the nth shell can in principle hold up to 2 (n2) electrons.
What is the total number of electrons in a subshell?
Subshell: Total Number of Electrons in Shell: 1st Shell: 1s: 2: 2nd Shell: 2s, 2p: 2 + 6 = 8: 3rd Shell: 3s, 3p, 3d: 2 + 6 + 10 = 18: 4th Shell: 4s, 4p, 4d, 4f: 2 + 6 + 10 + 14 = 32
How many electrons can a second shell hold?
The second shell can hold a maximum of eight electrons. When this is filled, electrons go into the third shell, which also holds a maximum of eight electrons.
