Aluminum atoms have a larger size due to the presence of more electrons and the associated electron cloud that surrounds the nucleus. When aluminum loses three electrons to form Al³⁺ ions, it becomes positively charged and experiences a significant reduction in electron-electron repulsion. As a result, the ion's electron cloud shrinks, making Al³⁺ approximately one third the size of the neutral aluminum atom. This reduction in size reflects the loss of the outermost electron shell and the increased effective nuclear charge acting on the remaining electrons.

What is the electron configuration on a stable ion of aluminum?
The stable ion of aluminum is Al 3+, which means it has three fewer electrons. The aluminum atom has shed its outer shell of 3s2 3p1 and has an electron configuration equal to that of Neon, or 1s2 2s2 2p6.
What is the chemical sign for aluminum?
The chemical symbol for aluminum is Al.
Aluminum ion has how many electrons?
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 formulas of the most common ions of these elements are Al+3 and Cl-1.
How many electrons are present in aluminum?
13 in the neutral atom, 10 in the Al3+ ion
When an aluminum atom loses it's valence electrons what is the charge on the resulting ion?
When an aluminum atom loses its three valence electrons, it becomes positively charged with a charge of +3. This results in an aluminum ion with a 3+ charge.
What is the name of Al3 and CN?
Al3 - Aluminum cationCN-Cyanide ion
What is the total number of electrons in an Al3 plus ion?
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.
What is the percentage of aluminum in aluminum oxide (Al2O3)?
The formula for aluminum oxide is Al2O3: Molar mass =581.77g/mol Al2O3.In one mole Al2O3, there are two moles of Al3+ ions, therefore 2 moles Al3+ x 26.982g/mol Al3+ = 53.964g Al3+ in one mole of Al2O3.GIVEN: mass of Al3+ = 53.964 g Al3+;Molar mass of Al2O3 = 581.77 g Al2O3UNKNOWN: % Al3+EQUATION:% Al3+...=...g Al3+x 100...g Al2O3% Al3+...=...53.964g Al3+x100......=...9.2758% Al3+581.77g Al2O3

What is the number of electrons in the valence shell of an atom of aluminum in the ground state?
An atom of aluminum in the ground state has 3 electrons in its valence shell. Aluminum has an electron configuration of 2-8-3, so its valence shell is the third shell, where the last 3 electrons reside.
