The easiest way to determine is to count the total number of electrons, which is 26 in this case and with the knowledge of the periodic table, one can easily identify this element to be Iron. Adding an electron to the ion would have the same energy (but opposite in sign) from removing the electron from the neutral atom. In other words, one process is the exact opposite of the other.

Writing the electron configuration requires that we recall how many orbitals are contained in each type of sublevel For example hydrogen with one electron has an electron configuration of 1s 1. The orbital diagram for hydrogen can be represented in the following way. The electron configuration of the chloride ion is: This is the same electron configuration as the neutral Argon atom. If two chemical species have the same electron configuration, they’re said to be isoelectronic. The preceding examples are all monoatomic (one atom) ions. But polyatomic (many atom) ions do exist. Then of course one electron would go away, because we lose one electron, and it be 3d10. Then for Cu2+ we basically would take away one more electron. So we would have 3d9, or one less electron. So it would take away one of the electrons for 4s, and one of the electrons from 3d, from the original atom. So that's for Copper.

The first ionization energy for sodium is one and one-half times larger than the electron affinity for chlorine. Na: 1st IE = 495.8 kJ/mol. Cl: EA = 328.8 kJ/mol. Thus, it takes more energy to remove an electron from a neutral sodium atom than is given off when the electron is picked up by a neutral chlorine atom.

In the examples you gave, the electrons would first be removed from the s orbital, then the d orbital. This is why there are no s orbitals present in the electron configuration for the ions that you gave. So for Ru 3+, you would first remove 2 electrons from the s orbital and one for the d orbital leading to a configuration of [Ar} 3d^5.
An electron configuration is a method of indicating the arrangement of electrons about a. nucleus. A typical electron configuration consists of numerical coefficients, letters, and superscripts indicating the following information: The numerical coefficient indicates the energy level (It also represents the principal quantum number; n). .

The electron configuration of the chloride ion is: This is the same electron configuration as the neutral Argon atom. If two chemical species have the same electron configuration, they’re said to be isoelectronic. The preceding examples are all monoatomic (one atom) ions. But polyatomic (many atom) ions do exist. Transitioning to a new period: an alkali metal easily loses one electron to leave an octet or pseudo-noble gas configuration, so those elements have only small values for IE. Moving from the s-block to the p-block: a p-orbital loses an electron more easily. An example is beryllium to boron, with electron configuration 1s 2 2s 2 2p 1. The 2s ... 8.44 One reason spectroscopists study excited states is to gain information about the energies of orbitals that are unoccupied in an atom's ground state.

See, though 4s is filled before 3d but after filling the electrons of 4s becomes more energetic to be removed before 3 d electrons. That means that the d is filled, and the s is ... The atom losing one or more electrons becomes a cation—a positively charged ion. The atom gaining one or more electron becomes an anion—a negatively charged ion. When the transfer of electrons occurs, an electrostatic attraction between the two ions of opposite charge takes place and an ionic bond is formed. An excited state means that (typically) the valence electron has moved from its ground state orbital (i.e. lowest available energy) to some other higher energy orbital. So any electron configuration in which the last electron (again, the valence electron) is in a higher energy orbital, this element is said to be in an excited state. For example, if we look at the ground state (electrons in the ...
