Question

How to make a sodium atom model?

Answer 1

Sodium Atom Model

• The element sodium is in the alkali metal group of the periodic table.
• An atomic number of any element refers to the number of electrons in an atom of that element they are having.
• Sodium Atomic number of $11$indicates that it has an equal number of $11$protons and $11$ electrons.
• Electronic configuration: $$\begin{gathered} \mathrm{K}\mathrm{L}\mathrm{M} \\ 281 \end{gathered}$$
• The sodium atom is represented as:

• In the model of Sodium has $11$electrons, its first shell will be fully occupied by two electrons, followed by its second shell occupied by eight electrons, thus leaving its third shell with just one electron.

Therefore, from the atomic number of an element, atom model should be drawn.
