The number of valence electrons determines reactivity. Valence electrons are the number of electrons in outermost shell.
Elements are more reactive as you go down the periodic table and to the left.
Potassium is the most reactive element with oxygen, readily reacting to form potassium oxide.
Plutonium is not highly reactive under normal conditions. It is a relatively stable element that does not react readily with air or water. However, it can be reactive in certain chemical reactions or when exposed to high-energy particles.
The number of electrons in an element determines its chemical properties and behavior. Specifically, it influences how an element will bond with other elements to form compounds and determines its reactivity.
This is called a displacement reaction. It occurs when a more reactive element displaces a less reactive element from its compound during a chemical reaction.
Fluorine is the most reactive element.
The element Californium is reactive.
Hydrogen is not only the lightest element of all, it is also very reactive.
Fluorine(F2) is the most reactive element, known to react with even Xenon, Krypton, Gold, Platinum, etc.
An element is said to be chemically reactive when it combines with another element. These two elements will create a new compound.
Yes, the number of protons in an atom of an element determines the element's identity. It determines the element's atomic number, which is unique for each element.
No that is not true. The number of PROTONS determines what the element is.
If by vital you mean most reactive, then the metal francium, Fr, is the most reactive element.
Potassium is most reactive with the element Oxygen. However, it should be noted that it is most reactive with a non-element: Water.
copper is very un-reactive. lead is more reactive.
