Germanium is in the fourth period of the Periodic Table. It exhibits two oxidation states GeII and GeIV
This tendency for a lower oxidation state is termed the "inert pair effect".
Looking at the halides GeF2 is a volatile white solid with an unusual structure which does not suggest that the bonding is ionic.
GeCl4 is a covalent molecular compound like CCl4 and SiCl4
the oxides GeO2 and GeO are both known but GeO is unstable disproportionates to GeO2 and metallic germanium. In the oxides the bonding but like silicon oxides, it is best described as covalent.
So in summary Ge2+ and Ge4+ (and these will probably be present in mass spectrometer beams) with the proviso that ions with a 4+ charge in reality are so strongly polarising that they will form bonds with a degree of covalency.
ionic
It will form an ionic bond. It will form GeF4 or Germanium QuadFloride.
Negative
Phosphite has an ionic charge of -3.
The ionic charge of Californium is 3+.
ionic
It will form an ionic bond. It will form GeF4 or Germanium QuadFloride.
Negative
The ionic charge of Californium is 3+.
Phosphite has an ionic charge of -3.
Germanium tetrachloride is covalent, just like carbon tetrachloride or silicon tetrachloride. All nasty stuff.
In ionic chlorine compounds, the ionic charge of chlorine is -1.
The ionic number is the positive or negetive charge an element has, such as Lithium has an ionic charge of +1.
The atomic number of germanium is 32. This tells us that germanium has 32 protons, and each of those has a +1 charge. So, in order to balance the charge back to 0, germanium must have 32 electrons as well.
Zero. A compound will never have a net ionic charge.
Germanium chloride is a bond between a metal and a nonmetal. The electronegativity difference between these substances is great. Thus, this compound has an ionic bond.
The net charge of any ionic compound is zero, in other words, ionic compounds are neutral.
