Question

show the electron distribution of a magnesium atom and a magnesium ion diagrammatically and also give their atomic number

Answer 1

magnesium-24 atomic no

Answer 2

Electron distribution of a magnesium atom and ion.

• When the number of protons and electrons are not equal in an atom, it is called ion whereas if both are equal it is called an element.
• The atomic number of elements represents the number of electrons and the number of protons present in it.
• Accordingly, the atomic number of magnesium is 12. It means that it contains 12 electrons and 12 protons. Thus it is called a magnesium atom.
• On the other hand, as the magnesium atoms due to valency 2, donates 2 electrons to bind with other atom and forms new product. Thus as magnesium donates 2 electrons, it becomes ion and has 10 electrons.
• Thus the electronic distribution of magnesium in the form of atom and ion is as follows

Magnesium atom : 2,8,2

Magnesium ion: $[2,8$$]^{2+}$

• The atomic number of both ion, as well as the atom, is 12.
• The electron distribution of a magnesium atom and a magnesium ion diagrammatically is given in the attachment.
