The octet rule says that
atoms become stable with 8 electrons in all their shells.
atoms become stable with 8 electrons in their valence shell.
atoms become stable with 8 electrons in all their 2nd shell.
atoms become stable with a total of 8 electrons.
Elements in group 2 are likely to form ions with a charge of
-2
+2
Elements in group 13 are likely to form ions with a charge of
+13
+3
-3
-13
Carbon and silicon do not form ions.
True
False
Two non-metal elements can form an ionic compound.
True
False
The reason that an electron is transferred from sodium to chlorine is that
sodium is more electronegative than chlorine.
sodium is less electronegative than chlorine.
sodium and chlorine are equally electronegative but chlorine has a space for another electron.
This picture indicates that
Mg is in group 12 & O is in group 8.
Mg is in group 2 & O is in group 16.
Mg is in group 2 & O is in group 6.
Mg is in group 12 & O is in group 16.
This picture demonstrates that in forming ions both Mg and O achieve a stable octet of valence electrons.
True
False
When Mg & Cl form an ionic compound, there is one Mg ion and two Cl ions because
the ratio of Mg to Cl ions can vary (MgCl, MgCl2, MgCl3 etc)
there will always be one Mg ion and two Cl ions (MgCl2).
there will always be one Mg ion and one Cl ion (MgCl).
