Question

s block element are very
​

Answer 1

s-block elements are the elements found in Group 1 and Group 2 on the periodic table. Group 1 are the alkali metals which have one valence electron. They have low ionization energies which makes them very reactive. Group 2 is the alkali earth metals which have two valence electrons, filling their s sublevel.

Answer 2

Answer:

Very Reactive.........

S-block elements are the elements with valence electrons in the s orbital. ... S-block elements are very reactive. Elements in column 1 (the alkali metals) always lose their one valence electron to form a +1 ion. Elements in column 2 (the alkaline earth metals) always lose their valence electrons to form +2 ions.
