This question is unclear. If you mean 3 full electron shells and nothing else, then it would be argon. But every element after argon has 3 full electron shells also, but they also have other shells with electrons. If you mean a full 3rd energy shell such as in having 3d10 electrons, then it would be Zn but Zn also has 4s2 electrons. So, the question is a vague one.
What else can I help you with?
What a period 3 element with 4 electrons in its outer shell?
n
What element has 2 electrons in the l shell?
The element with 2 electrons in the L shell is Lithium with atomic number 3. The electron configuration for Lithium is 1s^2 2s^1, meaning it has 2 electrons in the L shell.
How come the net charge of aluminum ions is plus 3 because there are-?
A neutral aluminum atom has 3 electrons in its outer shell and a full outer shell of 8 electrons below that. This full outer shell is stable, so aluminum will lose its 3 outer shell electrons to achieve that configuration.
Does indium need to gain 3 electrons to get a full outer shell?
Yes, indium needs to gain 3 electrons to achieve a full outer shell because it has 3 electrons in its outermost shell. By gaining 3 electrons, indium can achieve a stable octet configuration like the noble gases.
How many valence electrons are needed to make a full shell in a nitrogen atom?
3
How many electrons does the element B have in its outer shell?
Boron has 3 electrons in the outer shell and 2 electrons in the inner.
Is the inner lithium shell full?
Yes, Lithium has the Atomic Number 3, therefore has 3 electrons. The inner 'shell' of electrons only needs 2 electrons to be full. The Li+ ion also has a full inner shell.
The number of electrons in the outermost shell of an element is 5 what is its valency and why?
Its valency is 3 i.e. 8-5.The element is a non metal since it has 5 electrons in the outermost shell.Hence, it is very difficult for the element to loose 5 electrons and would be easier togain 3 electrons .Hence, the element gains 3 electrons and thus we consider its valencyto be 8- no. of valence electrons.
What element in period 3 consist of 3 electrons in its outermost shell?
aluminium
What element has 3 full shells?

What element has 2 electrons in the l shell?
The element with 2 electrons in the L shell is Lithium with atomic number 3. The electron configuration for Lithium is 1s^2 2s^1, meaning it has 2 electrons in the L shell.
An element that tends to lose 3 electrons?
Aluminum wants to lose three electrons. The atomic number of Al is 13, thus an uncharged Al has 13 electrons: 2 in the first shell, 8 in the second and 3 in the last shell. Since the element has 3 valence electrons it will try to lose them. As a result, it will have a charge of +3
How with 5 valence electrons will achieve a full set of valence electrons?
If you're asking how will an atom with 5 valence electrons will achieve a full set of valence electrons, then the answer would be that they bond with other atoms to gain a full set of the valence electrons by sharing or gaining 3 electrons.
How many element do the elements belonging two group IIIA have in there outermost shell?
Elements in group IIIA, also known as group 13, have 3 electrons in their outermost shell. This is because they are located in the third column of the periodic table, which determines the number of valence electrons an element has based on its group number.
How will you distinguish if an element is inert by the number of its valence electrons?
if the outermost shell of an element is completely filled that is, if it has 8 or 18 electrons which makes the outermost shell complete. Than we can say that the element has acquired the inert gas configuration.
How many electrons are in each orbit of electrons?
Well, the first valence electron shell contains 2 valence electrons, which every element has (with the exception of hydrogen), and all shells afterwards can hold up to 8 electrons. - So, by totaling, an element with 1 energy level full has 2 valence electrons, 2 full would mean 10, 3 full would mean 18, 4 full would mean 26, and so on.
