Question

PLEASE WRITE A PREFACE FOR MY CHEMISTRY PROJECT ON TOPIC S-BLOCK ELEMENT

Answer 1

The s-block elements consist of the alkali metals and alkaline earth metals, plus hydrogen and helium. Other elements of the s-block are all extremely powerful reducing agents that they never occur naturally in the Free State. Hydrogen and helium electrons are very easily lost to form positive ions in S-block elements. The helium configuration is chemically exceedingly stable and thus helium has no known stable compounds therefore these are generally grouped with the noble gases. The metallic forms of these elements can only be extracted by electrolysis of a molten salt. Water is much more easily reduced to hydrogen than the ions of these metals. The s-block metals vary from extremely soft (all the alkali metals) to quite hard (beryllium).

Answer 2

Actually you should write on your book because it is your home work and if you have a problem in the project ask. (sorry don't take this as mean k )

I hope you corporate
