Answer and explanation: **An atom can have five 5d orbitals**.

Four of the five 5d orbitals **consist of four trilobal lobes centered on the nucleus.** **The upper orbital consists of two trilobal lobes with a concentric pair of equatorial rings**.

Since gold is in the sixth period, it has the following d orbitals: 3d, 4d, and 5d. The 3d and 4d orbitals are each filled with 10 electrons, and the 5d orbital has **10 electrons**, for a total of 30.

For the d-orbital **the magnetic quantum number m _{l} can be equal to -2 to 2, taking the possible values -2, -1, 0, 1 or 2. This creates five d orbitals, d_{xy}, d_{yz}, d_{xz}, d_{x}^{ 2 }-y^{2} and d_{z}^{2}.**

There are **four types of orbitals** that you should be familiar with: s, p, d, and f (sharp, principle, diffuse, and fundamental). Within each shell of an atom there are some combinations of orbitals.

For 5d orbitals:

∴5d orbitals have **2 radial nodes and 2 angular nodes**.

5d series **consists of the elements La (atomic number 57) and from Hf (atomic number 72) to Hg (atomic number 80)**. These elements are in the 6th period. The elements of this series involve the gradual filling of 5d orbitals. Between La_{57} and Hf_{72} there are 14 elements viz.

These orbitals are denoted as d_{xy}, d_{yz}, d_{xz}, d_{x}^{ 2}_{–}_{y} ^{2} and d_{z}^{2}. Of these five d orbitals, the shapes of the first four d orbitals are similar to each other, which is different from the d_{z}^{2} orbital, whereas **the energy of all five d orbitals equals**.

There are five 4d orbitals. These are marked with **4d _{xy}, 4d_{xz}, 4d_{yz}, 4d_{x} ^{2< denotes /sup>-y 2 and 4dz 2}**. The name 4d

The value of the principal quantum number n for the 5d orbital is **5**.

**There are five 3D orbitals**. These are marked with 3d_{xy}, 3d_{xz}, 3d_{yz}, 3d_{x} ^{2} denotes -y ^{2} and 3d_{z} ^{2}. The name 3d_{z} ^{2} is an abbreviation for 3d_{(}_{3z} ^{2}–r ^{2}). Four of these features have the same shape but are spatially oriented differently.

Stefan V. The answer is A). The principal quantum number or n describes the energy level the electron can be in, since you are interested in an electron that is in a 5d orbital, **n=5** . The angular momentum quantum number or l describes the subshell or orbital type that your electron resides in.

**Starting at the third energy level, a set of five degenerate orbitals per energy level, energetically higher than s and p orbitals of the same energy level**.

Current theory suggests that electrons are housed in orbitals. An orbital is an area of space where there is a high probability of finding an electron. There are four basic types of orbitals: **s, p, d, and f**. An s orbital is spherical in shape and can hold two electrons.

**The principal quantum number (n)** describes the size of the orbital. For example, orbitals with n = 2 are larger than those with n = 1. Because they have opposite electric charges, electrons are attracted to the nucleus.

The values of the magnetic quantum number range from -l to l, so the possible values of ml for the 4d orbital are -2, -1, 0, 1 and 2. The values of ms are always +1/ 2 and -1/2. Therefore, **a total of 10 possible variations of quantum numbers for the 4d orbital are possible**.

The 3D subshell will have 5 orbitals. If we add all the orbitals of 3s, 3p and 3d, we get **9 orbitals** in total. Therefore, there are 9 orbitals in the third shell.

As such, there are **16 orbitals**. For n=5 the possible shells are s, p, d, f and g with 1, 3, 5, 7, 9 orbitals respectively. As such, there are 25 orbitals. For n=5 there are 25 orbitals.

The 3d orbitals are arranged quite compactly **around the nucleus**. Introducing a second electron into a 3d orbital creates more repulsion than if the next electron went into the 4s orbital. There is not a very large gap between the energies of the 3d and 4s orbitals.
