(1) in which period and group E should be placed?
(2) name the element E.
(3)how many electrons it needs to loose or gain to achieve noble gas configuration.
(4) what will be the nature of oxide ( acidic/basic ) of E?

** ik ik it’s a length question,.. but please help me out

Answer 1

magnesium is the element.
group- second group
period- third group
it needs to lose 2 electrons to achieve noble gas configuration. MgO is basic.
it's chloride is MgCl

Answer 2

Answer:

(1) period- 3 , group - 2

(2) magnesium

(3) 2 electrons need to loose to form noble gas configuration

(4) Basic in nature

(5) Mg + Cl2 ----- MgCl2 ( magnesium chloride)

Here your answer
