When a material undergoes a chemical change or reaction, the chemical property is a trait or activity that can be observed. Chemical properties may be detected during or after the reaction since the arrangement of atoms inside a sample must be disrupted to analyse the property.
Let us see some of the physical properties of Non-metals:
Reaction with Oxygen:
Non-metals react with oxygen to form oxides.
Reaction with Water:
Non-metals do not react with water, but they are very reactive in air.
Reaction with Acid:
Non-metals on reaction with acid
Non-metals do not react with dilute mineral acids but react with conc. sulphuric acids.
Reaction with Base:
Non-metals react with bases to form salt and water.
Displacement reaction: More reactive non-metal replaces a less reactive non-metal from its compound.
