My teacher said that metals lose electrons and non-metals gain electrons to complete the noble gas configuration because of stability as it consumes less energy but why are systems having high energy less stable as compared to systems having less energy.
Why do Nonmetals gain electrons? April 24, 2011, Hari M, Leave a comment. Why do Nonmetals gain electrons? Metals have very few electrons in their outer atomic shells and non-metals have more electrons in their valence shells and hence will tend to fill up the small gap in the valence shell. This makes the non-metals to gain electrons.
Nonmetals tend to gain electrons in order to achieve a full outer shell, so they are said to have high electronegativities. Alkaline metals, for example, would find it much easier to lose electrons than gain electrons, so they are not very electronegative. On the other hand, halogens such as chlorine only need to gain one electron to form a full outer shell.
All non-metals gain electrons except for the noble (or inert) gases of group 18 which don't readily react to anything. ... Metals transfer their electrons to nonmetals in order to reach the "octet ...
Non-metals gain electrons when forming ionic bonds, forming negatively charged ions. ... Metals transfer their electrons to nonmetals in order to reach the "octet" or 8 electrons in the valence shell.
In terms of gaining or losing electrons, the elements of the periodic table are classified into three categories: inert gases, nonmetals and metals. Generally, inert gases do not readily gain nor lose electrons, while nonmetals are more likely to acquire electrons.
Chemistry Unit Unit 4. STUDY. ... Metals tend to lose electrons and nonmetals tend to gain electrons. Why are most of the elements on the left and in the middle of the periodic table metals? ... will want to gain electrons from other elements in order to have a full outer shell.
Best Answer: Well if you look on your periodic table, you notice that most metals are on the left side of the table, indicating that they have either 1 or 2 electrons in their outer shell. Because of this, they are more willing to give up the 1 or 2 electrons in their outer shell in order to have a new complete outer shell (all atoms want to have a full outer shell - usually 8 electrons).
Metals lose electrons to form ions, a process that typically occurs between metals and non-metals. Because metals have a very low electronegativity, they lose electrons easily to high-electronegativity non-metals. Metals generally have very few electrons in their outer electron shell.
