Electron Deficient Compounds

Compounds that contain at least one atom (other than H) that shares fewer than eight electrons.

Pairing

A favourable interaction of two electrons with opposite m , values in the same orbital.

Percent by Mass

100% times the actual yield divided by theoretical yield.

How is colored crystal made?

However, not everyone knows that in addition to the traditional transparent, there is still an unusually beautiful and spectacular colored crystal, which is obtained through the addition of various metal oxides into the glass. They give the crystal unusually noble shades of red, purple, blue, green and pink colors.

Cathodic Protection

Density

Density is the ratio b/w Mass and Volume: D=M/V

Coordination Number
