A neutral atom has the following characteristics: - it has 1 valence electron - it's a main group element - the highest quantum level occupied is n = 4 What is the identity of this atom? Enter either the element name or symbol (case insensitive).
Since the element is of main group element and has valence electron 1.
So, the element belongs to group 1 (alkali metals)
And also it has highest quantum number 4, so it has [Ar] 4S1 configuration.
Therefore the element is K.
