What is the charge of an aluminum ion?

Before going towards the answer directly lets have a look at some facts

• The Helium atom is in second place in our modern table.
• Hence it is obvious that it has got only two electrons in its shell
• Also it is the first member of the Noble gas or Zero group elements family
• It is lightest Nobel gas present
• Very high ionisation enthalpy makes it very difficult to ionise

Now as Helium has only two electron they are very close to the nucleus

So it is very very difficult to create a doubly ionised helium ion by the way it can be represented as [math]He^2[/math][math]^+[/math]

Now in its second ionised state it has got no electrons left as both the two electrons available are removed

So it has a charge of +2

Note :: Charge on an atom is the total number of electrons it has lost or gained during ion formation. It will be positive if electrons are lost i.e and will be negative if electrons are added.

Also charge in ground state of an atom is always zero

Now lets have a look on the energy values

So first ionisation enthalpy of Helium to give [math]He^+[/math] is 2372 Kj or 24.62 eV

Second ionisation enthalpy of Helium to give [math]He^2[/math][math]^+[/math] is 5250 Kj or 54.49 eV

So overall energy required to remove both the electrons is 7622 Kj or 79.11 eV

1. Where eV is energy in Electron Volts
2. Kj is energy in Kilo joules

So as you can see energy required for this process is huge

Hope this extra information will come out handy

The question 'Does aluminum really cause the disease of Alzheimer's?' could be more accurately re-stated as 'Could exposure to aluminum cause Alzheimer's disease and could a causal link even be proven?' simply because aluminum is such a pervasive element in modern life, it's practically impossible to pinpoint frequency, duration and dosage of exposure at the individual level, let alone establish a cause-and-effect linkage between this one element, aluminum, on the one hand, and a complex, obviously multi-factorial disease such as Alzheimer's (AD) on the other hand. Simply, conclusive data's lacking. Rather epidemiological support of link between cumulative aluminum exposure and correlative risk of developing AD is confusing and inconclusive.

This answer

• Outlines some basic facts about aluminum as it pertains to degree and variety of biological exposure.
• Summarizes conclusions from some recent meta-analyses, and systematic and umbrella reviews on the link between Aluminum and AD.

Aluminum’s Pervasive in Human Foods, Daily Use Products and Environment

Third only to oxygen and silicon in its prevalence, aluminum is estimated the most abundant metal in the Earth's crust (1). Although there's as yet no evidence it is metabolized or even metabolizable by living things, its exponential industrial use from mid-20th century onwards has likewise exponentially increased human exposure to it. Though since the early 1970s, the pervasive soda can is a poster child of such use, it's far from the only one since aluminum has now become ubiquitous in not just human food and drinks but also in construction and the aircraft industry. After all, industrial aluminum use is pervasive, being used in everything from water treatment to generate drinking water to cosmetics, food, medical use and vaccines (see sequentially below from 1, 2),

'The largest markets for aluminium metal and its alloys are in transportation, building and construction, packaging and in electrical equipment. Transportation uses are one of the fastest growing areas for aluminium use. Aluminium powders are used in pigments and paints, fuel additives, explosives and propellants. Aluminium oxides are used as food additives and in the manufacture of, for example, abrasives, refractories, ceramics, electrical insulators, catalysts, paper, spark plugs, light bulbs, artificial gems, alloys, glass and heat resistant fibres. Aluminium hydroxide is used widely in pharmaceutical and personal care products. Food related uses of aluminium compounds include preservatives, fillers, colouring agents, anti-caking agents, emulsifiers and baking powders; soybased infant formula can contain aluminium. Natural aluminium minerals especially bentonite and zeolite are used in water purification, sugar refining, brewing and paper industries.'

Al atomic number is 13 which means it has 13 electrons and 13 protons. One basis of shell electronic configuration it has K(2),L(8) and M(3). . According to octet rule atoms having 1,2 and 3 valence electrons have ability to lose 1,2 and 3 electrons respectively. . As Al has 3 valence electrons as M(3) so it tends to lose electrons then after losing these 3 electrons it has 10 electrons and 13 protons, and 10 electrons are neutralized by 10 protons out of 13, and the further excess 3 protons out of 13 appear as +3 charge. That's why Al after losing its 3 valence electrons becomes Al+3. .

Aluminium is a metallic element and therefore occupies a place on the left hand side of the Periodic Table. Such elements tend to lose electrons in order to attain an ‘inert gas configuration’. Aluminium is in the third row of the Periodic Table and is in Group III. Hence it’s configuration is 2,8,3. Therefore it needs to lose 3 electrons to acquire the inert gas configuration of neon. Hence the charge on its ion is 3+.

A Charge (from what I know) is number on the top right corner of an element which shows the number of electrons needed to be lost or gained, for metals all the charges are +ve which shows that it should lose electrons, the number of electrons needed to be lost depends on the number of the outer shell electrons and all the outer shell electrons should be lost

for example:

Na (Sodium) has a charge of +1 which means that it has one electron in its outer shell which needs to be lost.

when it comes to non-metals the charges are shown as -ve which shows that electrons should be gained and the charge depends on how many electrons are needed to fill the outer shell electrons

for example:

O (Oxygen) has a charge of -2 which shows that it needs to gain to electrons to have 8 electrons in its outer shell

and last but not the least we have group four elements which have a charge of +4 or -4, group four elements can lose or gain electrons depending with which elements it reacts with

So to answer your question:

Al (Aluminum) is a group 3 element which means it has to lose three electrons therefore has a charge of +3

HOPE THIS HELPS !

Whatever you make it to be. Sure, some states are harder to achieve then others, some has such energies that would be highly unstable.

But charges from +13 to -something are all possible.

Okay, can someone fast do the math? When will the repulsion start to be so big that you can not cram another electron in? (e.g. Aluminium Fluoride? Aluminium Xenon? - as in high energy chemistry?)

Charge mainly is of two types, positive and negative charge.

In neutral condition atoms posses no charge having equal number of electrons(negativey charged particles) and protons(positively charged particles).

As Aluminum atomic number is 13, having 13 electrons and 13 protons, its electronic configuration is K(2) L(8) M(3). On the basis of octet rule Al tends to lose its three valence electrons which are M(3). When it loses its three valence electrons then it has 10 electrons and 13 protons. Due to excessive of three protons(positively charged particles) Al possesses +3 charge as Al+3. .

The word Ion does not specify charge. Only states that something is charged. Anions are negative and cations are positive.

Charge on aluminium ion is +3.

Because aluminium atom has 13 protons and electron initially. when it becomes an ion, it loses 3 electrons leaving behind only 10 electrons. now subtract the no of remaining electrons from the total no of protons.

13 ( total protons)-10 (remaining electrons)=+3, thus the aluminium ion is said to have a net positive charge of 3.

+3. Because last shell of aluminium atom has 3 electrons. In order to get a stable electronic configuration(2.8), Aluminium atom loses 3 electrons. So, the atom has 3 more protons than electrons. So, the charge of aluminium ion is +3.

Hope this answers your question.
