Answer:
1.- Chemical change
2.- Because the atoms in the image are tranformed into a new molecule
3.- Yes, it does
4.- Due to the amount of atoms are the same both in products and reagents
Explanation:
Answer: Option (b) is the correct answer.
Explanation:
Atomic number of magnesium is 12 and its electronic distribution is 2, 8, 2. Whereas atomic number of sulfur is 16 and its electronic distribution is 2, 8, 6.
So, in order to attain stability a magnesium atom needs to lose its 2 valence electrons and a sulfur atom needs to gain two electrons to completely fill its octet.
Hence, magnesium on losing two electrons will acquire a +2 charge and thus, it becomes a cation. On the other hand, sulfur on gaining two electrons will acquire a -2 charge and thus, sulfur will become an anion.
Thus, we can conclude that in the reaction between magnesium and sulfur, the magnesium atoms become cations.
