Question

which metal is more reative? why​

Answer 1

Answer:

From left to right:

Alkali metals are the most reactive, because (in case of metals) as we move along the period (from left to right ) the the reactivity decreases.

From top to bottom:

The bottommost metals are most reactive, because (in case of metals) as we move along the group (from top to bottom) the reactivity increases.

Answer 2

Answer:

caesium and magnesium is the most reactive metals..

they react harshly when released into air or room temperature..they also react vigorously when put into water..

when they are released into air they form oxides..such as caesium oxide and magnesium oxide

These metals are reactive because as metal ions are positively charged as they lose negetive electrons.some metals lose up their electrons more quickly and readily then others and are therefore more reactive..

this is the ans

hope this will help you
