Germanium is in the same family with the elements carbon and silicon. They all have
four electrons
in their outer shell.
How many shells do the electrons in germanium occupy?
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 and valence electrons does germanium have?
Germanium atoms have 32 electrons and 32 protons with
4 valence electrons
in the outer shell. Under standard conditions Germanium is a hard, shiny, silvery-gray solid that is very brittle.
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 |

Why the Valency of germanium is 4?
Each has four valence electrons, but germanium will at a given
temperature have more free electrons
and a higher conductivity.
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.
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.
What makes germanium unique?
Germanium is a lustrous, hard, gray-white semi-metallic element with a crystalline and brittle structure. It is a semiconductor. Germanium and the oxide are transparent to infrared radiation. Germanium also has the unusual property that
(like water) it expands as it freezes
.
Is germanium neutral?
Germanium atoms have 32 electrons and the shell structure is 2.8. … The ground state electron configuration of ground state gaseous neutral germanium is
[Ar]
.
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.
Is the third shell 8 or 18?
The third shell in its lowest state has room for 8 electrons but including the higher energy 3d electrons it has a capacity of
18 electrons
.
How many electrons can the 4 shell hold?
n= Shell Maximum Number of Electrons | 2 2nd Shell 8 | 3 3rd Shell 18 | 4 4th Shell 32 |

Which is Eka Aluminium?
Eka-aluminium was the name given by Mendeleev to the undiscovered element which now exists by the name of
Gallium
. Gallium belongs to group 13 of the periodic table. Its atomic number is 31 with the symbol Ga . It is a soft, silvery metal at standard temperature and pressure.
How can we find valency?
Mathematically we can say that if the outermost shell of an atom contains 4 or less than 4 electrons, then the valency of an element is equal to the number of electrons present in the outermost shell and if it is greater than 4, then the valency of an element is determined by
subtracting the total number of electrons
