Respuesta :
Lithium and sodium are the most similar because they are both Main Group metal elements located in the same Group and therefore have similar properties. Nitrogen and oxygen are not the most similar because although they are both elements Nonmetal, are each located in a different Group. Titanium and gallium are not the most similar because titanium is a Transition Metal and gallium is a Main group metal. Germanium and arsenic are not the most similar because although they are both Metalloid elements, they are each located in a different Group. Argon and bromine would not be the most similar because although they are both Nonmetal elements, they are each located in a different Group and Period.
Note: The Ar is a noble gas, that is its most representative difference
