The modern periodic law is as follows- In the periodic table, the physical and chemical properties of the elements repeat periodically with their atomic number depending upon the electronic arrangement of the elements. 

Solid CO2 is called dry ice.

The element or compound which absorbs water from other substances is called a dehydrating agent. 

At normal pressure (1 atm), the temperature at which a solid matter turns into a liquid state is called melting point of the solid substance.

The table used to arrange the discovered elements until now on the basis of their nature, properties, and electronic configuration is called the periodic table.

Rust is a hydrated ferric oxide (Fe2O3·nH2O). If iron is kept exposed in the open air, it undergoes a reaction with oxygen and water vapor and produces ferric oxide known as rust. Rust is a common name for iron oxide, which is a type of corrosion that forms on iron or steel when it is … Read more
