The noble gas that is isoelectronic with an aluminum ion is neon. Both the aluminum ion (Al^3+) and neon have 10 electrons.
Al3+
An aluminum ion, Al3+, has 10 electrons. This is because aluminum normally has 13 protons and 13 electrons in a neutral atom, but in the +3 ion it loses 3 electrons, leaving it with 10 electrons.
The number of neutrons in an aluminum ion can vary depending on the isotope. The most common isotope of aluminum is 27Al, which has 14 neutrons. However, other isotopes of aluminum exist with different numbers of neutrons.
+3 ion
Al2(SO4)3
Cobalt tetraoxosulphate (vi) ion
The chemical formula for aluminum phosphate is AlPO4. This means that aluminum phosphate contains one atom of aluminum for every one phosphate group. Therefore, aluminum phosphate contains one atom of aluminum per molecule.
Aluminum hydroxide contains the Al(III) ion and the hydroxide (OH-) ion.
The hydronium ion is simply the water ion with an extra proton. (H+) So: H2O + H+ ---> H3O+
The element with atomic number 13 is aluminum (Al). When aluminum loses three electrons, it forms an ion with a 3+ charge, written as Al3+. This ion contains 13 protons, as the number of protons in an element's nucleus is equal to its atomic number.
The name of the ionic compound CoSO4 is cobalt(II) sulfate.
The compound Al(CN)3 is aluminum cyanide. It is formed by combining one aluminum ion with three cyanide ions.
The name for the compound formed from aluminum and nitrate ion is aluminum nitrate.
Aluminum ions carry a charge of three. Al3+.
The ion of aluminium is 'three plus' Symbollically 'Al^(3+)'.
The noble gas that is isoelectronic with an aluminum ion is neon. Both the aluminum ion (Al^3+) and neon have 10 electrons.
