Why is Fe3+ ions more stable than co3+ ion?
Fe3+ ion is more stable due to its half-filled 3d5 electron configuration. As half filled and completely filled shells are more stable Fe3+ ion is more stable.
Why are Mn2+ compounds more stable than Fe2+ compounds?
Species try to attain the state of exactly half-filled and completely filled subshells configuration. Mn2+ has extra stability as it has exactly half filled configuration of 4s° 3d5 in its outermost shell while Fe2+ has 45° 3d6 configuration. Since Mn2+ has half filled orbital thus it is more stable to Fe2+.
Which element has more stable?
The noble gases are the chemical elements in group 18 of the periodic table. They are the most stable due to having the maximum number of valence electrons their outer shell can hold.
What is the difference between Fe2 and Fe3?
The difference between Fe2+ and Fe3+ is the Fe2+ has a pale green colour and turns violet when water is added to it. While Fe3+ forms blood-red when it reacts with thiocyanate ions. Fe2+ has paramagnetic properties whereas Fe3+ has diamagnetic properties.
Which is more stable Fe+3 or Fe+2?
The stability depends on whether you are checking it in gaseous or solution medium. In gaseous medium Fe+3 is more stable due to d5 half filled orbital. But in solution medium Fe+2 is more stable. This is because in solution medium reaction of Fe+3 reduction to Fe+2 has positive standard reduction potential. So due to this Fe+2 becomes more stable
Why is Fe2+ more stable than Fe⁴⁺ in the ionization reaction?
Ionization reaction is energy consuming (endothermic) process, so the electron richer Fe²+ is more stable (in thermodynamic sense) than Fe⁴⁺. In compounds, iron can have many different stable oxidation states, depending on its chemical environment. In most common complexes of iron, both +2 and +3 oxidation states are very stable.
How many protons and electrons does Fe+3 have?
Fe atomic number is 26 which means it has 26-electrons and 26-protons. When Fe loses three electrons then three protons become excess in Fe which appear as Fe+3. Now after losing three electrons, Fe has 23-electrons and 26-protons and these 23-electrons are being neutralized by 23-protons out of 26-protons.
How do you write the electronic configuration of Fe2+ and Fe3+?
First of all write down the electronic configuration of Fe (26). (Shown in the picture) Then write down the Fe2+ electronic configuration by removing 2 electrons from the outer most (4s) shell. Then write down the Fe3+ electronic configuration by removing 3 electrons, 2 from the outer most (4s) shell and 1 from 3d shell.
