No, only the noble gases in the far right column have a full valence shell.
No, metalloids typically do not have a full valence shell of electrons. They have properties that are in between metals and nonmetals, which means they can exhibit characteristics of both types of elements.
Noble gases have a full valence shell with 8 electrons, while all other groups typically have fewer valence electrons. Transition metals have varying numbers of valence electrons depending on their position in the periodic table.
Metals react with non-metals to achieve a stable electron configuration. Metals tend to lose electrons to achieve a full outer shell, while non-metals tend to gain electrons to fill their outer shell. This transfer of electrons between metals and non-metals results in the formation of ionic compounds.
Metals tend to lose electrons to form positive ions because, for metals to gain a full outer shell, they need to lose electrons.
the electrons on their outer shell, all atoms want to gain a full valence shell.
it needs six more electrons to have a full outer valence shell.
Oxygen needs 2 more valence electrons to have a full outer shell. Oxygen has 6 valence electrons, and a full outer shell for oxygen is achieved at 8 valence electrons.
Valence electrons of any atom are located in the outermost shell that atom carries electrons. For example a carbon atom has 6 electrons: 2e in its first shell (which is full) and 4e (valence electrons) in second shell--there are no electrons farther than second shell for carbon.
A full set of valence electrons typically consists of 8 electrons, except for hydrogen and helium, which have a full valence shell with 2 electrons.
All eight: the shell is full.
If magnesium (Mg) has a full valence shell, it would have a 2+ charge. This is because magnesium has 2 valence electrons and would need to lose these electrons to achieve a full valence shell, resulting in a 2+ charge.
