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.
Periodate (/ p ə ˈ r aɪ. ə d eɪ t / pə-RY-ə-dayt) is an anion composed of iodine and oxygen.It is one of a number of oxyanions of iodine and is the highest in the series, with iodine existing in oxidation state +7.
Magnesium iodide is an inorganic compound with the chemical formula Mg I 2. It forms various hydrates MgI 2 ·xH 2 O. Magnesium iodide is a salt of magnesium and hydrogen iodide. These salts are typical ionic halides, being highly soluble in water.
A magnesium(I) dimer is a molecular compound containing a magnesium to magnesium bond (Mg-Mg), giving the metal an apparent +1 oxidation state. Alkaline earth metals are commonly found in the +2-oxidation state, such as magnesium. The M 2+ are considered as redox-inert, meaning that the +2 state is significant. [1]
Organomagnesium chemistry, a subfield of organometallic compounds, refers to the study of magnesium compounds that contains Mg-C bonds. Magnesium is the second element in group 2 (alkaline earth metals), and the ionic radius of Mg 2+ is 86 pm, which is larger than Be 2+ (59 pm) and smaller than the heavier alkaline earth metal dications (Ca 2+ 114 pm, Sr 2+ 132 pm, Ba 2+ 149 pm), [1] in ...
The compound appears to be highly unstable but can react with alkenes to give halogenated products. [ 7 ] Radical iodine oxide (IO), iodine dioxide (IO 2 ), collectively referred to as I x O y and iodine tetroxide ((I 2 O 4 ) all possess significant and interconnected atmospheric chemistry.
[Mg(H 2 O) 6] 2+ → [Mg(H 2 O) 5 (OH)] + + H 3 O + (decomposes in water) MgCl 2 ·nH 2 O → Mg(OH)Cl + HCl + (n-1)H 2 O (decomposes when heated) Magnesium chloride is an ionic compound, which can be electrolysed in a molten state to form magnesium and chlorine gas. The properties of magnesium bromide and magnesium iodide are similar.
Iodine dioxide is a binary inorganic compound of iodine and oxygen with the chemical formula IO 2. [1] [2] Only stable as a dilute gas, [3] this compound is one of many iodine oxides, [4] [5] and "iodine dioxide" is sometimes used to describe its formal dimer, the salt diiodine tetroxide (I 2 O 4, [IO] + [IO 3] −).
