Character of S block element
Answers
Answer
shiny, silvery, good conductor and form salt with halogens.
Explanation:
Answer:s block elements have spherical s orbital as their outermost orbital.
1.Since s orbital can accommodate a maximum of 2 electrons, each one of these elements have 1 or two electrons.
2.These s electrons are lost very easily to form monopositive ions by lsoing one electron in the outermost orbital or dipositive ions by losing 2 electrons.
3.They have low ionisation potentials and low electronegativities.
4.They are good conductors of heat and electricity, excepting H2 and He.
5.They are silvery, shiny metallic substances, (with the exception of hydrogen and helium which gaseous nonmetals).
6.They are malleable and ductile, i.e., we can make sheets and wires from them, (exception: H2, He)
7.They readily form ionic salts with most nonmetals.
8.Aqueous solutions of their oxides are alkaline.
9.They are listed in two columns at the left end of the Periodic Table, exception: He, which is at the right end.
10.The first column elements are called the alkline metals and the second column ones are called alkaline-earth metals.
11.The elements in he s block are: Column 1: H, Li, Na, K, Rb, Cs and Fr. Column 2: Be, Mg, Ca, Sr, Ba and Ra. He is included in the last column.
12.There are many more, which are not listed here.
