Lista de cinco químicos usados diariamente en nuestros hogares.
1) Jabón (ésteres)
2) sal
3) Grafito (en lápices)
4) azúcar
5) Peróxido de hidrógeno (enjuague bucal)
Explanation:
Los productos químicos son esenciales en nuestra existencia diaria, ya que utilizamos productos químicos como fuente de energía, curación, limpieza e impresión.
The atoms combine to form compounds to attain stability in nature. The combination of atoms takes place by sharing of electrons between the atoms or complete transfer of electrons from one atom to another. Generally, atoms combine to complete their octet, that is to possess eight electrons in their outer most shell (noble gas configurations) except hydrogen which can attain stability by two electrons in its outer most shell.
Since germanium has 4 electrons in its outer most shell so it needs 4 more electrons to complete its octet and attains the stability. Hydrogen has 1 electron in its outer most shell and it needs only 1 electron to attain stability so, each germanium will combine with 4 hydrogen atoms and thus forming molecule which is stable in nature.
Hence, is the formula of the hydride formed by germanium.
If you are looking for a one specific electron you will have 90% chance of finding it in an area within the atom electron clouds.
According to the wave mechanical or electron cloud model of the atom, postulates that the atomic orbital is a region in space where there is a very high probability of finding an electron.
The term "electron cloud" is just another term used for "atomic orbital".
Since electrons reside in orbitals, if you are looking for a one specific electron you will have 90% chance of finding it anywhere within the electron clouds. This would make mathematical sense as the probability of finding an electron within the electron cloud can never be 100%.
