If the question is an attempt to ask "How many orbitals are there with principal quantum number n = 2", then 4 orbitals which can hold a total of 8 electrons.
An atom of silicon has three electron shells or orbitals. These are the K, L, and M shells. The K shell can hold up to 2 electrons, the L shell can hold up to 8 electrons, and the M shell can hold up to 18 electrons.
Chlorine has three electron orbital shells. The electron configuration for chlorine is 2-8-7, indicating that it has 2 electrons in the first shell, 8 electrons in the second shell, and 7 electrons in the third shell.
Boron has two orbital shells. The first shell contains 2 electrons, while the second shell can hold up to 8 electrons. Boron typically has 5 electrons, with 2 in the first shell and 3 in the second shell.
Sulfur has 3s, 3p, and 3d orbitals, making a total of 9 orbitals.
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
The second shell in an atom contains 4 orbitals and can hold up to 8 electrons.
8 electrons can be accommodated in the 2nd shell (aka 2nd energy level). 2 in the 2s orbital and 6 in the 2p orbitals.
There are three p orbitals in a p-shell, labeled as px, py, and pz. Each can hold a maximum of 2 electrons.
In the second energy level, there are four orbitals - one 2s orbital and three 2p orbitals.
The third shell can hold a maximum of 18 orbitals. This includes one 3s orbital, three 3p orbitals, and five 3d orbitals, totaling nine orbitals. Each orbital can hold a maximum of 2 electrons.
There are four types of orbitals in the sixth shell: s, p, d, and f orbitals. The s orbital is spherical, the p orbitals are dumbbell-shaped, the d orbitals are cloverleaf-shaped, and the f orbitals have more complex shapes. Each type of orbital can hold a specific number of electrons.
3 shells; 2 electrons in the first shell, 8 in the second shell and 8 in the third shell.
Krypton is a noble gas and hence has stable electronic configuration. Its valence shell configuration is 4s2 4p6 . Therefore, it has 1-s and 3-p full orbitals in its valence shell.
The second energy level, also known as the second shell, can hold a maximum of 8 electrons.
An atom of silicon has three electron shells or orbitals. These are the K, L, and M shells. The K shell can hold up to 2 electrons, the L shell can hold up to 8 electrons, and the M shell can hold up to 18 electrons.
There are three p orbitals in all levels 2 and above. these are the px, py and pz orbitals, the (suffix is the direction - px lies along the x axis). In the 5th level they will be 5px, 5py, 5pz
Only four in each have been observed.
