How has the electric clock improved since it was made?
The first reliable electric clocks kept time with synchronous motors geared to the alternating-current cycles of electric power. They were replaced by quartz clocks that rely on the steady vibrations of a quartz crystal for higher accuracy. The next improvement was the 'atomic clock', which provides extremely accurate time by monitoring the electromagnetic radiation of cessium atoms, and synchronizes household 'atomic clocks' by radio transmission.
What is the ionic compound for cesium phosphite?
The name phosphite is according to IUPAC reserved for PO33- ion, so Cesium phosphite would be Cs3PO3 However no compounds containing PO33- are known to exist. Hypothetical compounds containing it are often used in naming exercises by teachers/colleges/web sites. Phosphite in common use refers to HPO32- ion (IUPAC name phosphonate) and this is the formula taught in some parts of the world, cesium phosphite would therefore be Cs2HPO3
