Which is more stable pt4+ or ni4+?

A compound has more thermodynamic stability if the ionization energy of the metal is low. Pt4+ compounds are stable than Ni4+ compounds because the energy needed to remove 4 electrons in Pt is less than that in Ni.

What is the most stable form of an aluminum ion?

Concluding, isolate atom of Al is more stable than any ionized form. However Al³⁺ is the most stable in ionic compounds in both solid state and aqueous solution.

Why is aluminum more stable as an ion?

But the charge of the nucleus increases from +8 on Oxygen to +13 for Aluminum. So the same number of electrons is Aluminum (Al3+) will be bound much closer to the nucleus than the electrons of O2-. For a series of isoelectronic ions, the size decreases as the nuclear charge, z, increases.

How does Al become a stable ion?

Ions: Positive and Negative. Atoms have no electric charge, because they maintain an equal number of protons (positively charged subatomic particles) and electrons, subatomic particles with a negative charge. Yet like all metals, aluminum is capable of forming an ion by losing electrons—in this case, three.

Why is Ni2 thermodynamically more stable than Pt 2?

Since the ionization energy of Ni2+ is less than that for Pt2+, therefore Ni2+, compounds are thermodynamically more stable than Pt2+ compounds. Pt4+ compounds are stable than Ni4+ compounds because the energy needed to remove 4 electrons in Pt is less than that in Ni.

Why iron is more stable in +3 oxidation state than in +2 and the reverse is true for manganese?

why iron is more stable in +3 oxidation state than in +2 and the reverse is true for manganese? ​ – Brainly.in.

Why does aluminum form a 3+ ion?

The charge of an aluminum ion is typically 3+. This is because the element’s atomic number is 13, reflecting the fact that it has 13 electrons and 13 protons. 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.

What is the charge on the most stable ion of al group of answer choices?

Well, we have 123 So it’s going to take three lost electrons in order for it to reach that point. So losing electrons means you need to become positive. So it actually loses three electrons, making it an overall charge of three. Plus that is going to be the most able ion for aluminum.

Why does aluminum lose 3 electrons?

Aluminum is a Group IIIA element which means it has 3 electrons in it’s outer most shell, other wise known as each atom of aluminum has 3 valence electrons. It’s easier to lose 3 electrons than gain 5 electrons to fill the outer shell.

Why are larger ions more stable?

Negatively charged ions are also common intermediates in reactions. Like cations, anions are frequently unstable species. The more polarizable the atom, the more stable the anion. Within a row of the periodic table, the more electronegative an atom, the more stable the anion.

Why is Mn 2 more stable than Mn 3 plus?

It has five unpaired electrons in its d-orbitals which is maximum value for a transition metal ion. While Mn+3 ion has electronic configuration [Ar] 3d4 4s0. Mn+2 ions are more stable than Mn+3 ions.

Which is the stable oxidation state of Mn and why?

Mn. The most stable oxidation state (oxidation number) for manganese is 2+, which has a pale pink color, and many manganese(II) compounds are common, such as manganese(II) sulfate (MnSO4) and manganese(II) chloride (MnCl2).

Why is Alal+3 more stable than al+1?

Al+3 is more stable than Al+1 because Al+3 reaches its highest oxidation state. Al+3 is a ionic form of Al atom. It lost 3 valence electrons and in order to follow the octet rule. 12.8ev which is more than 11ev (limit) so lower is more stable.

Why does Al3+ lose more electrons than AL1+?

Because Al3+, having lost more electrons than Al1+, experience a greater force of attraction on its remaining outermost electrons, pulling closer to the centre of the ion, thus resulting in a higher amount of energy needed to remove the electrons within the remaining outermost electron shell.

Which element has the first ionization energy greater than Al?

Logic & solution: The outer electronic configurations of atoms, univalent and divalent cations of elements mentioned in above statement are tabulated below. Statement-1 is correct since, the electron has to be removed from full filled s-orbital, the first ionization energy of Mg is greater than that of Al.

Why are neutral atoms more stable than Al2+ atoms?

Thus, neutral atom is more stable than Al⁺ that is, in its turn, more stable than Al²⁺. These data (from Molar ionization energies of the elements – Wikipedia) show this trend: Isolated atom are not stable respective to loss of electron because ionization energy is energy consuming.
