Li is the only group 1 element which forms a stable nitride, Li 3 N. [4] Mg, as well as other group 2 elements, also form nitrides. [4] Lithium carbonate, phosphate and fluoride are sparingly soluble in water. The corresponding group 2 salts are insoluble. (Think lattice and solvation energies). Both Li and Mg form covalent organometallic ...
The chemistry of lithium shows several differences from that of the rest of the group as the small Li + cation polarises anions and gives its compounds a more covalent character. [5] Lithium and magnesium have a diagonal relationship due to their similar atomic radii, [ 5 ] so that they show some similarities.
A related effect can be seen in other diagonal similarities between some elements and their lower right neighbours, specifically lithium-magnesium, beryllium-aluminium, and boron-silicon. Rayner-Canham [ 72 ] has argued that these similarities extend to carbon-phosphorus, nitrogen-sulfur, and into three d-block series.
Disodium phosphate is a very selective reagent for magnesium ions and, in the presence of ammonium salts and ammonia, forms a white precipitate of ammonium magnesium phosphate. Mg 2+ + NH 3 + Na 2 HPO 4 → (NH 4)MgPO 4 + 2Na + Ca 2+ Ca 2+ forms a white precipitate with ammonium oxalate. Calcium oxalate is insoluble in water, but is soluble in ...
The chemical state set comprises and encompasses these subordinate groups and entities: chemical species, functional group, anion, cation, oxidation state, chemical compound and elemental forms of an element. This term or phrase is commonly used when interpreting data from analytical techniques such as: Auger electron spectroscopy (AES)

Lithium iron phosphate or lithium ferro-phosphate (LFP) is an inorganic compound with the formula LiFePO 4. It is a gray, red-grey, brown or black solid that is insoluble in water. The material has attracted attention as a component of lithium iron phosphate batteries, [1] a type of Li-ion battery. [2]
A mnemonic is a memory aid used to improve long-term memory and make the process of consolidation easier. Many chemistry aspects, rules, names of compounds, sequences of elements, their reactivity, etc., can be easily and efficiently memorized with the help of mnemonics.
