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 Mass is larger than atomic number , bcoz atomic number represents only number of proton in the atom , while the atomic mass represents number of proton and neutron both.
The term for freshly generated atomic number 1 (hydrogen) in a reactive form is nascent hydrogen.
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.
Cesium (Cs) shows the least active chemical behavior among these elements. It is located at the bottom of Group 1 in the periodic table and has the largest atomic radius, making it the most reactive metal in Group 1. Rb (Rubidium) and Na (Sodium) are more reactive than Cs.
The atomic number of Barium (Ba) is 56. It indicates the number of protons found in the nucleus of a Barium atom, which also determines its unique chemical properties.
An atom with atomic number zero and mass number zero does not exist in nature. The atomic number represents the number of protons in the nucleus, and an atom must have at least one proton to be stable.
18
The atomic number for sodium (Na) is 11. This means that sodium has 11 protons in its nucleus.
The term for freshly generated atomic number 1 (hydrogen) in a reactive form is nascent hydrogen.
An atom with an atomic number of 10 (neon) is less reactive than an atom with an atomic number of 5 (boron) because neon has a full valence shell, making it stable and less likely to form chemical bonds. Boron, on the other hand, has fewer electrons in its outer shell, making it more reactive as it seeks to gain electrons to achieve stability.
The element with an atomic number of 19 is potassium, which is a reactive metal that is essential for various biological processes.
chlorine is more chemical reactive than argon.
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.
Fluorine is the most reactive non metal.Caesium is most reactive metal in the table.Fluorine has atomic number 9.
All alkali (not alkaline-earth) metals are extremely reactive with water, but within the group, lithium is the least reactive.
Potassium's atomic symbol is K and its atomic number is 19.
That would be the element with the highest atomic number but the lowest number of valence electrons.
Yes,Fluorine is the most reactive non metal.It has atomic number of 9.It is the lightest Halogen.
