Why is aluminum in the non metal category of the periodic table? - non aluminum anti perspirant
If we look at the periodic table, aluminum is the group of non-metal or boron group. If it is metal, why not?

Non Aluminum Anti Perspirant Why Is Aluminum In The Non Metal Category Of The Periodic Table?

In fact, Al is in the category of metal-AP
Can you see, B, Si, Ge, As, Sb, Te, Po, on the stairs?
They are known as metalloids.
On the basis of these metalloids, if the elements are on the right side of the metalloids nonmetals.
When items are on the left side of the metalloids, which are considered as metals. Thus, Al is in the metal category.
The third column, or main group includes the periodic table of elements metal mainly. Metals, the atoms, the electrons in chemical reactions tend to lose. Aluminum fits perfectly into this definition. The atoms of the elements in aluminum and lose electrons in metals. The different "element of this column is boron in the top of the column. The metal atoms tend to lose electrons to a stable electron configuration is achieved. Al has 13 electrons and lose 3 electrons, so that the ion 10 10 electrons (the 1 and) fill the second level of energy - a stable electronic configuration. A boron only 5 electrons. It would also lose 3 electrons to an ion with a stable electronic structure form, but separate the electrons from an atom, the electrons are closer to basis and is difficult to remove. A boron do not lose 3 electrons in chemical reactions normal and not technically a metal, but Al and the elements are certainly in metal.
