Nobelium have valences +2 and +3.
Nobelium primarily forms ionic bonds. This is due to its tendency to lose electrons and achieve a stable electron configuration similar to noble gases.
Nobelium is a synthetic element that does not naturally occur in nature in appreciable quantities. Therefore, it does not typically participate in chemical reactions in the way that common elements do. Magnesium is a group 2 metal that can form a 2+ ion in reactions. An ionic equation involving magnesium and nobelium would not be feasible due to nobelium's radioactive and artificial nature.
Phosphite has an ionic charge of -3.
The ionic charge of stannous (tin) is typically +2.
The ionic charge of bromate ion (BrO3-) is -1.
Iodine typically has an ionic charge of -1.
The ionic charge of chloride ions is -1.
The compound is K2SO4 (potassium sulfate) Potassium (K) has a 1+ ionic charge. Sulfur (S) has a 2- ionic charge. Oxygen (O) has a 2- ionic charge.
H2O (water) is a neutral molecule, so it does not have an ionic charge.
The ionic charge for CoN is -3. This is because cobalt (Co) has a 3+ charge, and nitrogen (N) has a 3- charge, resulting in a neutral ionic compound when combined.
