The gaseous element with 5 valence electrons and fewer neutrons than sodium is Boron. Boron has 5 protons and 5 neutrons, while sodium has 11 protons and about 12 neutrons.
Oxygen is the element that has 8 valence electrons and is in the gaseous state at room temperature.
Fluorine has 7 valence electrons, (9 altogether) and ten neutrons.
The element is sulphur. It has 5 valence electrons and 16 neutrons.
An element with 7 valence electrons is likely in Group 17 of the periodic table, such as chlorine. With 74 neutrons, it corresponds to the isotope chlorine-81.
This element is likely chlorine (Cl), which has 7 valence electrons and 3 filled energy levels with a partially filled 4th energy level.

one valence electron
They don'tThey group elements with the same number of valence electrons.The valence electrons of an element determine how that element bond and how many bonds it forms.So elements with the same number of valence electrons tend to have similar chemical properties.
