state atom of one element has two s electrons in its outer shell, and no d electrons anywhere in its configuration. The other element has d electrons in its configuration. Identify the elements. Solution The elements are in Group IIA. They must also be in Periods 4 (no d electrons) and 5 (d electrons). Therefore, the elements are calcium (Ca ... Although it is commonly stated that all the electrons in a shell have the same energy, this is an approximation. However, the electrons in one subshell do have exactly the same level of energy, with later subshells having more energy per electron than earlier ones. This effect is great enough that the energy ranges associated with shells can overlap (see valence shells and Aufbau principle).If you know that the ocupation number of is defined as 2(2L+1), where L is the orbital angular momentum, or it is 2J+1 , where, J=s L +S , where S is the spin which is 1/2.

this is just my guess, but even though QM say that there are different rules down at sub atomic levels, i believe that the electrons behave that way because of centrifugal forces, and therefore do not want to fill the outer shell but have to because they are moving so fast. Its electron structure is 2, 8, 8, 1. An atom that has the maximum number of electrons in its outer shell will be stable. This means that it will not react with other atoms. It belongs to a group called the noble gases. When the outer shell has the maximum number of electrons, the electron shells are said to be full.All of these elements can lose a single electron forming a cation with a +1 charge. All of the elements in the column on the far right (inert or Nobel gases) have two s electrons and eight p electrons in their outermost level (called the valence level). Note that the Periodic Table has the shape of a distorted "H".

And what'll you bet that it would like to loan that electron out?

How Many Electrons Does Carbon Have? A carbon atom typically possesses six electrons - two in its inner shell and four in its outer shell. This number varies due to a number of circumstances, but a stand-alone atom with no charge contains six electrons. 

An atom has the tendancy to lose electrons (to another atom) or to gain electrons (from another atom) in order to make the outer shell complete with eight electrons. Atoms with a complete outer shell (eight electrons) are considered stable. Aluminum has 13 electrons in a neutral atom. The 1S2, 2S2 and 2P6 shells are full, and so is the 3S2. The 3P1 shell has one electron in it (in Al's neutral atom) and that gives aluminum one lone valence electron and two "semi-valence" electrons which can be loaned out. And what'll you bet that it would like to loan that electron out? C) outer-shell electrons of two atoms are shared so as to satisfactorily fill the outer electron shells of both atoms.

Each subshell has a maximum number of electrons which it can hold: s - 2 electrons, p - 6 electrons, d - 10 electrons, and f - 14 electrons. The s subshell is the lowest energy subshell and the f subshell is the highest energy subshell. As was mentioned previously, the shell number is equal to the possible number of subshells.

Its electron structure is 2, 8, 8, 1. An atom that has the maximum number of electrons in its outer shell will be stable. This means that it will not react with other atoms. It belongs to a group called the noble gases. When the outer shell has the maximum number of electrons, the electron shells are said to be full.An atom with one or two electrons less than a closed shell is reactive due to its tendency either to gain the missing valence electrons and form a negative ion, or else to share valence electrons and form a covalent bond. Similar to an electron in an inner shell, a valence electron has the ability to absorb or release energy in the form of a ...
