There are three 4p orbitals in an atom. Each orbital can hold up to 2 electrons with opposite spins.
A bromine atom has 7 half-filled orbitals: one in the 4s orbital, three in the 4p orbitals, and three in the 4d orbitals.
In an arsenic atom, there are three half-filled orbitals. These are the 4s, 4p, and 4d orbitals. Each of these orbitals can hold a maximum of 2 electrons, so there are a total of 6 electrons in the half-filled orbitals of arsenic.
The valence electrons in a bromine atom are located in the 4s and 4p atomic orbitals. Bromine has 7 valence electrons, with two in the 4s orbital and five in the 4p orbitals.
There are three 4p orbitals: 4px, 4py, and 4pz. Each orbital can hold a maximum of two electrons.
The last orbital to fill in a bromine atom is the 4p orbital. Bromine has a total of 35 electrons, with the electron configuration of [Ar] 4s2 3d10 4p5. The 4p orbital can hold a maximum of 6 electrons.
The central atom in BrCl3 is bromine (Br). The bromine atom in BrCl3 adopts sp3d hybridization, which involves the mixing of one 4s, three 4p, and one 4d atomic orbitals to form five sp3d hybrid orbitals.
A potassium (K) atom has one electron in the 4s orbital. There are no p-orbitals occupied in a potassium atom.
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.
The hybridization of the central atom (Cl) in ClF5 is sp3d2. This means that the 3d, 4s, and three 4p orbitals of chlorine hybridize to form six equivalent sp3d2 orbitals, allowing for the five bonding pairs of electrons in the molecule.
The element germanium has four valence orbitals: one 4s orbital and three 4p orbitals. This gives a total of four orbitals.
Iron has 3d, 4s, and 4p orbitals. So, it has a total of 6 orbitals.
