How many valence electrons does GE have?

The 32nd element of the periodic table is germanium. The element of group-14 is germanium and its symbol is ‘Ge’. Germanium forms bonds through its valence electrons. This article discusses in detail how to easily calculate the number of valence electrons in germanium. Hopefully, after reading this article you will know in detail about this.

• What are the valence electrons of germanium?
• How do you calculate the number of valence electrons in a germanium atom?
• How many valence electrons does germanium ion(Ge2+, Ge4+) have?
• What is the valency of germanium?

The nucleus is located in the center of the atom. Protons and neutrons are located in the nucleus. The atomic number of germanium is 32. The atomic number is the number of protons. That is, the number of protons in germanium is thirty-two. Electrons equal to protons are located in a circular shell outside the nucleus. That is, a germanium atom has a total of thirty-two electrons.

What are the valence electrons of germanium?

The third element in group-14 is germanium. The valence electrons are the total number of electrons in the last orbit(shell). The total number of electrons in the last shell after the electron configuration of germanium is called the valence electrons of germanium. The valence electrons determine the properties of the element and participate in the formation of bonds.

How do you calculate the number of valence electrons in a germanium atom?

The valence electrons have to be determined by following a few steps. The electron configuration is one of them. It is not possible to determine the valence electron without electron configuration. Knowing the electron configuration in the right way, it is very easy to determine the valence electrons of all the elements.

However, valence electrons can be easily identified by arranging electrons according to the Bohr principle. Now we will learn how to determine the valence electron of germanium.

Step-1: Determining the total number of electrons in germanium

1st we need to know the total number of electrons in the germanium atom. To know the number of electrons, you need to know the number of protons in germanium. And to know the number of protons, you need to know the atomic number of the germanium element.

To know the atomic number we need to take the help of a periodic table. It is necessary to know the atomic number of germanium elements from the periodic table. The atomic number is the number of protons. And electrons equal to protons are located outside the nucleus.

That is, we can finally say that there are electrons equal to the atomic number in the germanium atom. From the periodic table, we see that the atomic number of germanium is 32. That is, the germanium atom has a total of thirty-two electrons.

Step-2: Need to do electron configuration of germanium

Step-2 is very important. In this step, the electrons of germanium have to be arranged. We know that germanium atoms have a total of thirty-two electrons. The electron configuration of the germanium shows that there are two electrons in the K shell, eight in the L shell, eighteen in the M shell, and four in the N shell(orbit).

That is, the first shell of germanium has two electrons, the second shell has eight electrons, the 3rd shell has eighteen electrons and the 4th shell has four electrons. The number of electrons per shell of germanium is 2, 8, 18, 4.

Step-3: Determine the valence shell and calculate the total electrons

The third step is to diagnose the valence shell. The last shell after the electron configuration is called the valence shell(orbit). The total number of electrons in a valence shell is called a valence electron. The electron configuration of germanium shows that the last shell of germanium has four electrons. Therefore, the valence electrons of germanium are four.

How many valence electrons does germanium ion(Ge2+, Ge4+) have?

The electron configuration shows that the last shell of germanium has four electrons and the d-orbital has a total of ten electrons. The ionic state of the element changes depending on the bond formation. Ge2+ and Ge4+ ions exhibit germanium atoms.

Ge – 2e– → Ge2+

Here, the electron configuration of germanium ion is 1s2 2s2 2p6 3s2 3p6 3d10 4s2. This electron configuration shows that the germanium ion(Ge2+) has four shells and the last shell has two electrons.

In this case, the germanium ion(Ge2+) has a total of two valence electrons. On the other hand, the germanium atom donates two electrons in the 4p orbital and two electrons in the 4s orbital to convert the germanium ion(Ge4+).

Ge – 4e– → Ge4+

Here, the electron configuration of germanium ion(Ge4+) is 1s2 2s2 2p6 3s2 3p6 3d10. This electron configuration shows that the germanium ion(Ge4+) has three shells and the last shell has eighteen electrons. In this case, the valence electrons of the germanium ion(Ge4+) are eighteen.

What is the valency of germanium?

The ability of one atom of an element to join another atom during the formation of a molecule is called valency(valence). The number of unpaired electrons in the last orbit of an element is the valency of that element. Valency is determined from the electron configuration of the element in the excited state.

The electron configuration of germanium(Ge*) in excited state is 1s2 2s2 2p6 3s2 3p6 3d10 4s1 4px1 4py1 4pz1. Here, the electron configuration of germanium shows that four unpaired electrons exist in the last orbit of germanium. Therefore, the valency of the germanium atom is 4.
