ionic
Mg(OH)2 is an ionic compound. It consists of magnesium ions (Mg2+) and hydroxide ions (OH-), which are held together by ionic bonds.
Pure ionic in Mg(OH)2 = Mg2+ and 2 OH-
Mg is the scientific symbol for the element magnesium :)
Mg is an ionic element. It typically forms cations with a 2+ charge by losing two electrons to achieve a stable electronic configuration.
No, Mg(NO2)2 is ionic. It consists of magnesium ion (Mg2+) and two nitrite ions (NO2-), which are held together by ionic bonds.
Balanced Molecular:2HBr + Mg = MgBr2 + H2Net Ionic:2Br- + Mg = Mg2+ + 2 Br-
MgBr2 is an ionic compound. Magnesium (Mg) is a metal and bromine (Br) is a non-metal, so they form an ionic bond by transferring electrons.
Mg(NO3)2 is an ionic compound. It consists of magnesium cations (Mg2+) and nitrate anions (NO3-), which are held together by ionic bonds due to the transfer of electrons from magnesium to nitrogen and oxygen atoms.
Mg(OH)2 is an ionic compound. Magnesium hydroxide is composed of magnesium ions (Mg2+) and hydroxide ions (OH-), which are held together by ionic bonds.
'Mg' (Magnesium) is an elemental METAL It is NOT a molecule . The atoms are held together in a metallic lattice. It is NOT ionic per se. However, it readily ionises , by loosing two(2) electrons to form the cation 'Mg^(2+)'. It is this cation that combines ionically.
Ionic Molecular
No such substance as 'Mgcl'. If you mean magnesium chloride, then the formula is 'MgCl2'. Note the number and the capital letters. All substances, however they combine are molecules; so it is molecular. However, it is NOT covalent , but IONIC. Magnesium ionises two electrons to become the cation 'Mg^(2+)'. Chlorine has electron affinity , and accepts one electron , per atom, to become the chloride anion 'Cl^(-)'. These ions then combine as Mg^(2+) + Cl^(-) + Cl^(-) = Mg^(2+) + 2Cl^(-) = MgCl2.
