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.

The number of neutrons is variable.
This element is likely chlorine (Cl), which has 7 valence electrons and 3 filled energy levels with a partially filled 4th energy level.
The element with 6 valence electrons is carbon.
An element with seven valence electrons is likely to be a member of group 17 on the periodic table, which includes halogens like chlorine, bromine, and iodine. If we consider the atomic mass of the element and subtract the number of neutrons (74) to find the atomic number, we can conclude that this element is likely to be iodine, which has an atomic number of 53. Therefore, iodine has seven valence electrons and typically has around 74 neutrons in its most common isotope, I-127.
Boron has 3 valence electrons.Boron has 3 valence electrons.
Ununoctium has 118 protons, 118 electrons and 176 neutrons.
