NASCENT hydrogen
You would have to give me number to compare but I would say the one with the higher atomic number. The atomic number is the number of protons in the nucleus, so I would assume that the more protons an atom has, the more reactive it is. like with a magnet, if you have two or three magnets, they will be reactive, but if you have seven or eight, they will be much MORE reactive. Hope this helps!
Atomic Number is 47; Atomic Mass is 137.3; Element Name is Barium; Classified as the Alkaline Earth Metals.
Could you please re-ask your question in a better manner, because that question does not make sense. Are you trying to ask the atomic mass of the element with the atomic number of 7? or are you just stating that there is an element with the atomic number of 7? because that is not a very good question.
Noble gasses are least reactive of all the elements. So the least reactive element in the period 4 is Krypton. It is a noble gas with an atomic number of 36.
Quite possibly francium (Fr, atomic number 87) is the most reactive element. Collecting a sample large enough to view is currently impossible, as it would vaporize due to the extreme heat of its decay. The longest isotopic half life of francium is 22 minutes.
Sodium is very reactive. Highly reactive with water. eleven is the atomic number.
Boron (atomic number 5) is more reactive than neon (atomic number 10).

chlorine is more chemical reactive than argon.
Fluorine is the most reactive non metal.Caesium is most reactive metal in the table.Fluorine has atomic number 9.
Vanadium is a chemical element with the symbol V and an atomic number of 23. It is moderately reactive and only becomes more reactive with hot acids.
That would be the element with the highest atomic number but the lowest number of valence electrons.
Among the elements aluminum, silicon, cesium and fluorine, cesium is the most reactive metal. It has the chemical symbol Cs and atomic number 55.
Argon (atomic number 18) is the noble gas that is nearest to calcium (atomic number 20)
