Final answer:

This answer provides detailed information on the protons, neutrons, electrons, valence electrons, ion symbol, periodic table group, and electron configuration of atom X.


Explanation:

Protons: 19
Neutrons: 20
Electrons: 19

Valence electrons are the outermost electrons. In atom X with 19 electrons, the outer energy level likely has 1 electron.

Upon ionization, atom X would form an ion with a +1 charge, so the ion symbol would be X+.

Atom X, with atomic number 19, belongs to Group 1 of the periodic table known as the alkali metals.

Electron configuration using the mathematical approach: 1s2 2s2 2p6 3s2 3p6 4s1 and quantum mechanics approach: [Ne] 3s2 3p6
