The elemental state of aluminum tends to lose electrons. Its ionic state is 3+ which means it is most likely to lose up to 3 electrons.


It will lose its three outer electrons in an ionic bond making it a 3+


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


Elements in Groups 1 and 2, sometimes 3, of the periodic table [elements with 1, 2, and 3 valence electrons, i.e. potassium (K), calcium (Ca), and aluminum (Al), respectively]


Aluminium should gain 5 electrons or lose 3 electrons. It will normally lose 3 electrons to form Al3+ ion, rather than gaining 5 electrons and forming Al5- ion.


In the electronic configuration when the last shell is filled with 1,2 or 3 electrons then the element tends to give out electrons. when elements give out these 1,2 or 3 electrons it becomes positive these positive atoms are metals


Aluminum's electron configuration is 13. It has three outermost electrons. It tends to donate three electrons to form the stable Aluminum(III) ion.


The chemical element lithium (Li) has 3 protons and 3 electrons.


Lost because it is easier for the element to lose 3 electrons and become an octet than it is to gain 5 electrons.


It needs to gain 3 electrons than to lose 5 electrons. So phosphorus has to gain 3 electrons.




Aluminium lose 3 electrons and form the cation Al3+.



Lithium is element #3, and it has 3 electrons.


The expected number of valence electrons for a group 3 A element is 5 number of valence electrons.


There could not be 4 electrons. That should be lithium if it has 3 electrons.


The element lithium has 3 protons and 3 electrons.


The number of protons will never change, and if they do, the element will change to a different element. Therefore, the only element with 3 protons is lithium. When forming an ion, it will lose one electron in order to have a full outer shell.


Lithium atoms have three electrons.



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.


they gain 3 electrons and lose 1-2 electrons.. sometimes they do..!


That varies, element #3 will have 3, element 4 will have 4, etc. However, they all have 2 valence electrons.


The period 3 element with 6 valence electrons is sulfur.
