Answer 2

$\boxed{\bf{ \blue{\bigstar Answer\longrightarrow }}}$

• The number of valency electrons are the electrons which are less than 8 or more than eight
• i.e. If an element has configuration as (2,8,5).Then valency electrons are 3 and valency is -3
• So Here the configuration is (2,8,6) So valecy electrons are 2 and valecy is -2
• Here the element is Sulphur
• When sulphur combines With oxygen it can form either Sulphur dioxide or Sulphu trioxide. Which have burning smell of sulphur and are acidic Oxides..
