Many transition metals cannot lose enough electrons to attain a noble-gas electron configuration. In addition, the majority of transition metals are capable of adopting ions with different charges. Iron, which forms either the Fe 2 + or Fe 3 + ions, loses electrons as shown below. Fe → Fe 2 + + 2 e −

As electrons are added, they fill electron shells in an order determined by which configuration will give the lowest possible energy. The first shell (n=1) can have only 2 electrons, so that shell is filled in helium, the first noble gas.
These together provide a short-hand description of the state of the electrons in an atom or ion (I will use the terms interchangeably). The notation is confusing, is case-specific, and sometimes ambiguous. Quantum Numbers 4 quantum numbers suffice to describe any electron in an atom. These are: n, the principal quantum number. This is also ...

How to Write the Electron Configuration for Carbon. Carbon is the sixth element with a total of 6 electrons. In writing the electron configuration for carbon the first two electrons will go in the 1s orbital. Since 1s can only hold two electrons the next 2 electrons for C goes in the 2s orbital. The remaining two electrons will go in the 2p ...
An excited-state atom is an atom in which the total energy of the electrons can be lowered by transferring one or more electrons to different orbitals. That is, in an excited-state atom not all electrons are in the lowest possible energy levels. eg. Consider a carbon atom whose electron configuration is the following. Write the condensed electron configuration of a ground state atom of iron (Z=26)? Thank You!!! ... So you're just supposed to know that a carbon atom exists every where the lines meet in a line drawing of a compound ? ...

Nov 04, 2009 · Write the electron configuration for the following ion. V3+ I got 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2. In simplified form, I got [Ar]4s^2. I checked my answer against the answer given in the back of my chemistry textbook, and the two didn't correspond. The answer my book gives is [Ar] 3d^2. I don't understand what I did wrong... 7. What is the nuclear charge of an iron atom? (1) +26 (2) +30 (3) +56 (4) +82 8. Which of these elements has an atom with the most stable outer electron configuration? (1) Ne (2) Cl (3) Ca (4) Na 9. How many electrons are in the outermost principal energy level of an atom of carbon in the ground state?

The electronic configuration of an atom in the shell atomic model may be expressed by indicating the number of electrons in each shell beginning with the first. For example, sodium (atomic number 11) has its 11 electrons distributed in the first three shells as follows: the K and L shells are completely filled, with 2 and 8 electrons respectively, while the M shell is only partially filled ...

This configuration cannot be the ground-state electron configuration for a Mg atom because it violates the ... in a ground-state iron atom? a. 6 b. 18 c. 12 d. 24 e. 30 14. All of the following ground-state electron configurations are correct except a. Fe: [Ar]4s24d6 b. Ca: [Ar]4s2 c. In: [Kr]4d105s25p1 d.For technetium-98 and heavier isotopes, the primary mode is beta emission (the emission of an electron or positron), producing ruthenium (Z = 44), with the exception that technetium-100 can decay both by beta emission and electron capture. Technetium also has numerous nuclear isomers, which are isotopes with one or more excited nucleons.

So we have three ways to represent the electron arrangement in an atom. The orbital diagram, the electron configuration and the energy diagram. All three ways are useful. The next atom is helium with 2 electrons. So the second electron could go into the 1s orbital with the opposite spin of the first electron or it could go into the next orbital ...filled. For example, an atom of carbon has a total of 6 electrons. Starting with the 1s level, the electron configuration will be 1s 2 2s 2 2p 2. The number of electrons in each sublevel is given as superscripts. Iron, with 26 electrons, will be seen to have the configuration 1s 2 2s 2 2p 6 3s 2 3p 6 4s 2 3d 6. This scheme gives the correct ...
