Balanced chemical reaction: 3Mg + 2Fe(NO₃)₃ → 2Fe + 3Mg(NO₃)₂.
Oxidation number of iron in iron(III) nitrate is +3, oxidation number of magnesium in magnesium nitrate is +2.
The reactivity
series<span> is
a series of metals from highest to lowest reactivity. Metal higher in the
reactivity series will displace another, magnesium is more reactive than iron.</span>
Answer:
Aluminium.
Explanation:
The above electronic configuration can be written in a simplified form as shown below:
1s² 2s²2p⁶ 3s²3p¹
Next, we shall determine the number of electrons in the atom of the element as follow:
Number electron = 2 + 2 + 6 + 2 + 1
Number of electron = 13
Next, we shall determine the number of protons.
Since the element is in its neutral state,
The number of electrons and protons are equal i.e
Proton = Electron
Number of electron = 13
Proton = Electron = 13
Proton = 13
Next, we shall determine the atomic number of the element.
The atomic number of an element is simply the number of protons in the atom of the element i.e
Atomic number = proton number
Proton = 13
Atomic number = 13
Comparing the atomic number of the element with those in the periodic table, the element with the above electronic configuration is aluminium since no two elements have the same atomic number.

hahahahahahahahahahaha ur funnny

NOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOB
Answer:
On moving from left to right in a period the electropositive character decreases as the tendency to lose electrons decreases.
