(ii) Arrange the following metals in decreasing order of their reactivity:
Fe, Zn, Na, Cu, Ag​

Afusion reaction takes place between carbon and another element. neutrons are released, and a different element is formed. the different element is a) lighter than helium.b)heavier than helium.c)the same weight as helium.d)dependent on the element that reacted with carbon.

If a particle has z = 25 and 23 electrons, what is its charge?
