What element has the ground-state electron configuration of Ar4s23d6?

The element with the ground-state electron configuration of Ar4s23d6 is iron (Fe) with atomic number 26.


Why is iron not having closed shell configuration though its atomic number is 26?

Iron does not have a closed shell configuration because it has incompletely filled d-orbitals in its electron configuration. In the case of iron, the electrons in the 3d orbitals prevent it from achieving a closed shell configuration.


What is the electron configuration of iron?

Iron's atomic number is 26. Thus it has 26 protons and 26 electrons. The electronic configuration for the first 26 electrons, and so therefore iron, is Fe 1s2 2s2 2p6 3s2 3p6 4s2 3d6. The shorthand electron configuration is Fe [Ar] 4s2 3d6.


What is the electronic configuration of 26Fe?

The electron configuration of Fe (Iron) is 1s2 2s2 2p6 3s2 3p6 4s2 3d6, where the 26 represents the atomic number of Iron, showing that Iron has 26 electrons.


How do you create a periodic chart using 26 imaginary elements?

To create a periodic chart with 26 imaginary elements, you can assign unique symbols to each element, starting from element 1 to element 26. Organize the elements in rows and columns based on their properties and atomic number. You can also include other relevant information like atomic mass and electron configuration to make your periodic chart more detailed.


A neutral atom of iron-56 has how many electrons?

A neutral atom of iron-56 has 26 electrons. This is because the number of protons in an atom, which determines its atomic number, is equal to the number of electrons in a neutral atom. Iron has an atomic number of 26, so it has 26 electrons in a neutral state.
