Well, if you're asking about valence electrons, there are 3. Otherwise, there are a total of 13 electrons in a neutral Aluminum atom Electron Configuration [Al]: 2 - 8 - 3
There are 3 valence electrons in an atom of aluminium.
The element that forms a 3+ ion with ten electrons is sodium (Na). Sodium has 11 protons and normally has 11 electrons, but when it loses 3 electrons to form a 3+ ion, it has a total of 10 electrons.
The cation would be either sodium, magnesium or aluminium. The only oxyanion with 26 electrons is the hypochlorite ion. So the compound is sodium/magnesium/aluminium hypochlorite.
I do not understand the question Aluminium forms the Al3+ ion Aluminium is a metal and one description of metal bonding is that metals are latttices of ions surrounded by electrons.
An Al3+ ion has 13 protons, making it aluminum, and has lost 3 electrons. Since the number of electrons in a neutral aluminum atom is 13, the Al3+ ion has 10 electrons in total.
It would become an Aluminum ion that has a 3+ charge
Aluminium emit 3 electrons. It makes aluminium ion.
The neutral atom of aluminium has 13 electrons.
There are 3 valence electrons in an atom of aluminium.
Aluminium should gain 5 electrons or lose 3 electrons. It will normally lose 3 electrons to form Al3+ ion, rather than gaining 5 electrons and forming Al5- ion.
The element that forms a 3+ ion with ten electrons is sodium (Na). Sodium has 11 protons and normally has 11 electrons, but when it loses 3 electrons to form a 3+ ion, it has a total of 10 electrons.
The atomic number of Aluminium is 13. But the aluminium ion is lacking 3 electrons, so its electron configuration (10 e-) is as follows: 1s2 2s2 2p6 or in it abreviated form: [Ne] as it has the same number of electrons of Neon
The cation would be either sodium, magnesium or aluminium. The only oxyanion with 26 electrons is the hypochlorite ion. So the compound is sodium/magnesium/aluminium hypochlorite.
I do not understand the question Aluminium forms the Al3+ ion Aluminium is a metal and one description of metal bonding is that metals are latttices of ions surrounded by electrons.
The ion with 13 protons and 10 electrons would have a 3+ charge since there are more protons than electrons. Its formula would be Al3+, representing an aluminum ion with a 3+ charge.
There are 18 electrons in a chloride ion.
a cuprous ion has 28 electrons.
