This is a chemical element. You can find the how many electron in a single atom by using a Periodic Table.
The elements in the same period as sodium on the periodic table have the same number of electron orbitals. So, phosphorus, sulfur, chlorine, argon, potassium, calcium, and scandium would all have the same number of electron orbitals as sodium.
The electron configuration of calcium is 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2. This means that calcium has 20 electrons, with two electrons in the 1s orbital, eight in the 2s and 2p orbitals, and eight in the 3s and 3p orbitals, and finally two in the 4s orbital.
Boron has two electron orbitals - 1s and 2s. Each orbital can hold a maximum of 2 electrons.
Aluminium has three electron shells with 2,8,3 electrons each.
In a neutral atom of the element technetium (Tc), there are 6 electrons in the 4d orbitals. This is because the 4d orbitals can hold a maximum of 10 electrons, following the electron filling pattern.

atomic orbitals and electron orbitals
Aluminium has three electron shells with 2,8,3 electrons each.
In a neutral atom of the element technetium (Tc), there are 6 electrons in the 4d orbitals. This is because the 4d orbitals can hold a maximum of 10 electrons, following the electron filling pattern.
An atom of iodine has 53 electrons, and therefore has 53 electron-containing orbitals. This includes the s, p, d, and f orbitals.
Iodine has 7 electron-containing orbitals, corresponding to its 7 valence electrons in the p subshell. These orbitals can hold a maximum of 2 electrons each.
If it is in row 4 (4th period) it has 4 energy levels occupies. In the 2nd column (group 2A) it has 2 valence electrons. You ask how many orbitals it has. It has s and p orbitals. Is that what you mean? The configuration is 1s2 2s2 2p6 3s2 3p6 4s2 so there are 3 s orbitals and 6 p orbitals for a total of 9 orbitals.
Technetium has 43 electrons, so it has 43 orbitals.
Nitrogen has one electron in the 2s orbital and three electrons in the 2p orbitals.
The electron travels around the nucleus in orbitals, not orbits. Orbitals are regions of space where there is higher probability of finding an electron.
