+4 in its compounds
0 in the elemental form
The ionic radius of germanium can vary depending on its oxidation state. However, for germanium in its most common oxidation state of +4, the ionic radius is approximately 0.53 nanometers.
-1 is most common in chlorides. However chlorine can exhibit oxidation numbers up to +7 in its compounds.
-1 in bromide (most common). It can exhibit oxidation numbers from -1 to +7 (in HBrO4)
It is a gas. Generally it shows -2 oxidation number.
The most common oxidation numbers of fermium, Fm, are +2 and +3, though there are no stable isotopes (half-life times shorter than 100 days)
Germanium oxide can exist in different oxidation states: GeO, GeO2, and GeO3. GeO2, also known as germanium dioxide, is the most stable and commonly found oxide of germanium.
0 in elemental form. -2 is most common in its compounds (selenides)
The oxidation number of chlorine can vary depending on the compound it is in. It can have an oxidation number of -1 in most compounds, but it can also have positive oxidation numbers in compounds like ClO4- where it has an oxidation number of +7.
The most common oxidation states in the periodic table are +1, +2, +3, -1, -2, -3. These oxidation states are frequently observed in elements based on their position in the periodic table and their electron configuration.
-1 is most common, but Cl can exhibit oxidation numbers from -1 to +7 in its compounds.
The most common oxidation number of magnesium is +2.
the most common oxidation number for oxygen is -2.
