How Many Electrons Does Aluminum Need to Be Stable

The valence shell of aluminum has three electrons and per the octet rule these three electrons are lost resulting in just 10 electrons and 13 protons. Valence Electrons for Selenium How many valence electrons does selenium ionSe 2- have.

Answer 1 of 3.

. We know that aluminum atoms have a total of thirteen electrons. When it becomes an ion it loses 3 electrons leaving behind only 10. The charge of an aluminum ion is typically 3.

How many electrons are in a aluminum ion. 4 Answers By Expert Tutors. In ionic bonding phosphorus atoms need to gain 3 electrons to become stable forming phosphide ions P3-.

In other words its charge was neutral due to the equal numbers of protons and electrons. This is because the elements atomic number is 13 reflecting the fact that it has 13 electrons and 13 protons. Borons configuration however is 1s2 2s2 2p1.

O2 is perfectly stable but that doesnt mean it cannot react with other atoms to form compounds of lower energy. The valence shell of aluminum has three electrons and per the octet rule these three. The elements that have 5 6 or 7 electrons in the last shell receive the electrons in the last shell during bond formation.

Thereof how many electrons does aluminum need to gain or lose to become stable. In this step the electrons of aluminumAl have to be arranged. The O atom has electron configuration 2s22p22p12p1.

That means there are 2 half filled orbitals not well shielded from the nucleus that can accept 2 additional elec. So in this case aluminum wants to become stable by loosing three electrons but the ponostrophic energy required to loose them is to. From the periodic table we see that the atomic number of aluminum is 13.

This is because the elements atomic number is 13 reflecting the fact that it has 13 electrons and 13 protons. Initially the aluminum atom had a charge of 13 13 0. How many electrons does aluminum happy with.

Aluminum is a metal that will always lose three electrons. If you look at the periodic table Als atomic number is 13 so it must have 13 protons1 and resultantly 13 electrons -1 to balance out the charge. The elements that receive electrons and form bonds are called anions.

Now the charge is 13 10 3. Having 6 valence electrons would mean having a configuration of 1s2 2s2 2p4 which doesnt seem as stable as 1s2 2s2 2p6 or even as stable as 1s2 2s2 2p3 since one would think that there is repulsion going on between electrons in the first orbital of p in 1s2 2s2 2p4. Need to do electron configuration of aluminumAl Step-2 is very important.

That is an aluminumAl atom has a total of thirteen electrons. The charge of an aluminum ion is typically 3.
