Answer:
₁₅P = 1s² 2s² 2p⁶ 3s² 3p³
Explanation:
Phosphorus is the second element of group (v) with atomic number 15 and the electrons per shell are arrange as thus; 2, 8, 5.
The electronic configuration of phosphorus is
₁₅P = 1s² 2s² 2p⁶ 3s² 3p³
Or
₁₅P [Ne] 3s² 3p³
In its first shell I.e 1s shell, it has 2 electrons filling it to s-orbital requirement. In its second shell, electrons fill it in 2s² 2p⁶ filling the second orbital and attaining an octet configuration. The third shell contains 5 electrons filling 3s² 3p³ orbital.
For the crystallization purpose the combination of solvent process is known to be an effective process. But the solvent pair one have to choose crucially. The solvent which is completely in soluble into the other solvent can not work as a good solvent pair for the crystallization. The crystallization of any compound by the solvent pair process is depend upon the slow diffusion of a less polar solvent to the polar solvent or vice-versa.
If a compound is soluble in a polar solvent the slow diffusion of relatively low polar solvent will make crystal of the compound. But anyhow the solvents which are completely not immiscible to each other will not work for the purpose. Thus diethyl ether and water solvent pair can not be used for the crystallization process.
Answer:
Drought, resulting in a 65% reduction in water levels.
They speed up when they get hotter and they slow down when they get colder. I think
Answer:
difference between metal and alloy is that the metal is a pure substance whereas the alloy is a mixture of two or more components.
Explanation:
Mostly the metalloids have the appearance just like the metallic appearance And also they are the brittle one's . Boron and silicon are the example. Note; By combining with other metals metalloid can form the alloy
