Which element contains 5 electrons in its 3d orbitals?

Vanadium (V) contains 5 electrons in its 3d orbitals.


Why does the d block have only 10 elements?

The d block has only 10 elements because the d sublevel can hold a maximum of 10 electrons due to its 5 orbitals, each with a paired electron. This results in a maximum of 5 d orbitals accommodating a total of 10 electrons in the d block elements.


How many orbitals are in the f block in the elements chart?

There are 14 orbitals in the f block. This is because each f sublevel can hold a maximum of 7 orbitals, with each orbital being able to hold a maximum of 2 electrons.


What makes the d block wider than either the s block or the p block?

The d block is wider than both the s block and the p block because it contains five sublevels (d orbitals), each of which can hold up to 10 electrons. In contrast, the s block has only one sublevel (s orbital) that can hold 2 electrons, and the p block has three sublevels (p orbitals) that can accommodate a total of 6 electrons. This greater capacity of the d block is a result of the presence of additional orbitals, allowing for a wider range of electron configurations and chemical properties.


What are the orbitals that are occupied in fluorine F9?

Fluorine (F) has 9 electrons, with the electron configuration of 1s2 2s2 2p5. The orbitals that are occupied in fluorine are the 1s, 2s, and 2p orbitals. The 1s orbital contains 2 electrons, the 2s orbital contains 2 electrons, and the 2p orbital contains 5 electrons.


How many orbitals does sulfur have?

Sulfur has three electron orbitals. The first orbital contains 2 electrons, the second contains 8 and the third contains 6.


What shell contains a total of 9 orbitals?

The shell that contains a total of 9 orbitals is the third shell. This shell consists of one 3s orbital, three 3p orbitals, and five 3d orbitals, which adds up to 9 orbitals in total.


Why does the second row of the periodic table not have a d block section?

The second row of the periodic table corresponds to the filling of the 2s and 2p orbitals. The d block elements, which are transition metals, belong to the third period and beyond where the 3d orbitals start to fill. Since the d orbitals are not available until the third principal energy level (n=3), the second row does not include any d block elements. Thus, the second row contains only s and p block elements.


How many a orbitals are there in a sublevel?

5 orbitals


How many 3d atomic orbitals exist?

The 3rd period contains 2 of the 3 orbitals for the third sublevel. It has the s and p orbitals in it.


What are the electron levels?

Electrons don't have levels. They have shells and orbitals. Each shell contains certain orbitals. For example, the first shell contains only the s orbital. The second contains the s and p orbital. The fourth shell has the s, p, and d orbitals.


How many d orbital can there be in an energy level?

There are five d orbitals in one energy level. These orbitals are designated as dxy, dyz, dxz, dz2, and dx2-y2. Each d orbital can hold a maximum of 2 electrons.
