Answer: The ion formed is [tex]_{12}^{26}\textrm{Mg}^{2+}[/tex]
Explanation:
An ion is formed when an atom looses or gains electron.
- When an atom looses electrons, it will form a positive ion known as cation.
- When an atom gains electrons, it will form a negative ion known as anion.
Atomic number is defined as the number of protons or electrons that are present in a neutral atom.
Atomic number = number of protons = number of electrons
Atomic mass is defined as the sum of number of protons and neutrons that are present in an atom.
Atomic mass = Number of protons + Number of neutrons
The isotopic representation of an atom is: [tex]_Z^A\textrm{X}[/tex]
where,
Z = Atomic number of the atom
A = Mass number of the atom
X = Symbol of the atom
We are given:
Number of protons = 12
Number of neutrons = 14
Atomic Mass = 12 + 14 = 26
Number of electrons = 10
As, the number of electrons is less than the number of protons, it forms positive ion
Hence, the ion formed is [tex]_{12}^{26}\textrm{Mg}^{2+}[/tex]
The symbol for the ion is Mg²⁺
From the question given above, the following data were obtained:
Proton = 12
Neutron = 14
Electron = 10
Symbol of ion =?
Next, we shall determine the atomic number of the ion.
The atomic number of an element is simply the number of protons in the atom of the element.
Proton = 12
Atomic number = proton = 12
Thus, the ion is magnesium (Mg) ion since only magnesium has atomic number of 12
Finally, we shall determine the charge on the ion. This can be obtained as follow:
Proton = 12
Electron = 10
Charge =?
Charge = Proton – Electron
Charge = 12 – 10
Charge = +2
Therefore, the symbol of the ion is Mg²⁺
