Out of Na Mg and Al which is least reactive? And why?...

rohitkumargupta Al is the least reactive metal among these.

this is because Na and Mg have lesser no. of electrons in their outer shell ( Al has 3, Na has 1 & Mg has 2 ) , this makes them more reactive as t is easir 2 lose lesser no. of electrons on gain noble gas configuration
Hope it helps you dear

rohitkumargupta hoe

rohitkumargupta but you ask

rohitkumargupta least reactive

rohitkumargupta then

maheshwaranlupp0yaxy Al is least reactive among those 3 elements

rohitkumargupta ya right

....Here's ur answer....

⏩ Aluminum is the least reactive....

EXPLANATION -----

⭐ Electronic Configuration of Aluminum:: 2, 8, 3

⭐Electronic Configuration of Magnesium:: 2, 8, 2

⭐Electronic Configuration of Sodium:: 2, 8, 1

⏩We know that elements always want to obtain stability....
⏩To obtain stability the outermost shell of an element should be filled....

♦In these 3 cases we can able to see that if

➡Al loses its 3 electrons in its outermost shell it can obtain noble gas configuration....

➡Mg loses its 2 electrons in its outermost shell it can obtain noble gas configuration....

➡Na loses its 1 electrons in its outermost shell it can obtain noble gas configuration....

♦So....Here ,

Al is least reactive compared to Mg and Na...

❤.... Hope It Helps You... ❤
