Question

the atomic number of an element X is and that element of y12 write the symbol of iron you should accept to be formed from their atom​

Answer 1

Answer:

So symbols of the oxygen ion=O^{-2}O

−2

So symbols of the magnesium ion=Mg^{+2}Mg

+2

Explanation:

Since we know that atomic number is the protons which is available in the nucleus of an atom.

The atomic number of an element X is 8 so it is oxygen.

since valency of oxygen is 2.It can take two electron to complete its shell.

so symbols of the oxygen ion=O^{-2}O

−2

The atomic number of an element Y is 12 so it is Magnesium.

since valency of magnesium is 2.It can take give electron to complete its shell.

so symbols of the magnesium ion=Mg^{+2}Mg

+2

Answer 2

Answer:

The atomic number of an element X is 8 so it is oxygen. since valency of oxygen is 2.It can take two electron to complete its shell. The atomic number of an element Y is 12 so it is Magnesium. since valency of magnesium is 2.It can take give electron to complete its shell.
