Is this stuff isoelectronic with perchlorate? -- (talk) 15:41, 29 August 2008 (UTC)

Mn(VII) is [Ar] 3d0 4s0, i.e. just [Ar] = 1s2 2s2 2p6 3s2 3p6.
Cl(VII) is [Ne] 3s0 3p0, i.e. just [Ne] = 1s2 2s2 2p6.
So, yes, manganate, [MnVIIO4] and perchlorate, [ClVIIO4], are isoelectronic. Their valence electron configurations are both ns2 np6.

This page is getting vandalized by non-registered people., on 19 September 2012 changed the correct equation 2 MnCl2 + 5 NaClO + 6 NaOH → 2 NaMnO4 + 9 NaCl+ 3 H2O into 2 MnCl2 + 4 NaClO + 2 NaOH → 2 NaMnO2 + 6 NaCl+ 3 H2O and it went unnoticed. Vmelkon (talk) 22:01, 2 October 2012 (UTC)
