13al,14si,11na,12mg,16s which of the above elements has the highest metallic character?
Answers
Answer:
silicon has the highiest mettallic character
Answer:
Answer :
Electronic configuration:
⇒ The atomic number of aluminum = 13
The electronic configuration of 13Al = 2,8,3
⇒ The atomic number of silicon = 14
The electronic configuration of 14Si = 2,8,4
⇒ The atomic number of sodium = 11
The electronic configuration of 11Na = 2,8,1
⇒ The atomic number of magnesium = 12
The electronic configuration of 12Mg = 2,8,2
⇒ The atomic number of sulphur = 16
The electronic configuration of 16S = 2,8,6
Among the given elements, Na has highest metallic character (most electropositive element
Explanation:
Explanation:
All the given elements have total three shells present in them which means all the elements belong to the same period (period 3).
⇒ The metallic character decreases as we move from sodium to sulphur in a period.
⇒ Hence, Na has the high tendency to loose electrons.
⇒ Thus, sodium (Na) has the highest metallic character.
