Germanium is in the same family with the elements carbon and silicon. They all have
four electrons
in their outer shell. The orbital structure for germanium is 2-8-18-4.
How many shells does germanium have?
Germanium is in the same family with the elements carbon and silicon. They all have
four electrons
in their outer shell.
How many electrons does each outer shell have?
In general, atoms are most stable, least reactive, when their outermost electron shell is full. Most of the elements important in biology need
eight electrons
in their outermost shell in order to be stable, and this rule of thumb is known as the octet rule.
How many electrons does germanium have?
Name Germanium | Atomic Mass 72.61 atomic mass unit | Number of Protons 32 | Number of Neutrons 41 | Number of Electrons 32 |

How do you find the outer shell electrons?
So we can use the column or group of an element to determine the number of electrons in its outermost shell, sometimes referred to as
valence
electrons. Elements from the fourth column of the periodic table, like carbon, have four electrons in their outermost electron shell or four valence electrons.
Why is 3rd shell 8 or 18?
In this sense the third shell
can hold 8 electrons
. 4s2 not the third shell, but the next 10 electrons go into the 3d orbitals that are part of the third shell but shown on the fourth shell level. … So the third shell can be considered to hold 8 or 18 electrons but in total the third shell can hold 18 electrons.
How many electrons are in the third shell?
Energy shell Maximum number of electrons | First 2 | Second 8 | Third 8 |

Is germanium harmful to humans?
Germanium is not an essential element.
Its acute toxicity is low
. However, at least 31 reported human cases linked prolonged intake of germanium products with renal failure and even death. Signs of kidney dysfunction, kidney tubular degeneration, and germanium accumulation were observed.
Where do we find germanium?
They are found in small quantities as the
minerals germanite and argyrodite
. Germanium minerals are also present in zinc ores, and commercial production of germanium is carried out by processing zinc smelter flue dust. It can also be recovered from the by-products of combustion of certain coals.
What is the chemical symbol of germanium?
Germanium |
Ge
– PubChem.
What are the electrons in the outer shell called?
The number of electrons in the outermost shell of a particular atom determines its reactivity, or tendency to form chemical bonds with other atoms. This outermost shell is known as the
valence shell
, and the electrons found in it are called valence electrons.
Which element has a full outer shell of electrons?
Group 0 elements –
helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe)
and radon (Rn) – have full outer shells. (Group 0 is sometimes called Group 8 – all the elements in the group have eight electrons in their outer shell, except for helium which only has two).
Why are there only 8 electrons in the outer shell?
This is due to
the quantum nature of the atoms
, where electrons are arranged into shells: there are 2 electrons in the first called the K shell, 8 in the second (L-shell), 18 in the third (M shell). …
What is the 2 8 8 rule in chemistry?
There is a 2-8-8 rule for these elements.
The first shell is filled with 2 electrons, the second is filled with 8 electrons, and the third is filled with 8
. You can see that sodium (Na) and magnesium (Mg) have a couple of extra electrons. They, like all atoms, want to be happy.
Is it 8 or 18 electrons in third shell?
So the
third shell
can be considered to hold 8 or 18 electrons but in total the third shell can hold 18 electrons.
Can the third shell hold 18 electrons?
Each shell can contain only a fixed number of electrons: The first shell can hold up to two electrons, the second shell can hold up to eight (2 + 6) electrons, the third shell can hold up to
18
(2 + 6 + 10) and so on.
