According to the periodic table, a sodium atom forms \(Na^+^1\) ion by losing two electrons correctly describes the change from a neutral atom of an element to its ion.
What is a neutral atom?
A neutral atom is an atom where the charges of the electrons and the protons balance.
Atomic number 11.
Mass number 23.
Na Electron arrangement 2, 8 , 1 Will lose 1 electron to gain a full valence shell.
Since now 11 + and 10 –, the overall charge is 1+ So we write \(Na^+^1\) or simply \(Na^+\).
