You think probable to the mass conservation.
The types and numbers of atoms at the end of a reaction are the same as before the reaction.
Assuming that you are referring to chemical reactions, we know that atoms are not changed by chemical reactions (except for their oxidation states). That means that all the same types of atoms are present after the reactions as were there before the reactions. The type of an atom is determined by the number of protons in its nucleus.
The element with mass number 260 does not exist naturally. However, an artificial element with the mass number 260 could be produced in a nuclear reaction involving a heavy nucleus and would likely be a radioactive isotope.
When chemical bonds are formed or broken during a chemical reaction, the molecules' arrangement changes, leading to products with different properties than the reactants. This process involves the breaking of existing bonds in reactant molecules before new bonds form in the products.
Energy may only be transformed from one sort to another. Mass is a form of Energy and as such, must be, and is, conserved. It is 'of no surprise' then, that the number of atoms that enter a chemical reaction is equal to the number of atoms that exist after the reaction has been completed.
no racism existed before slavery
Nothing existed before creation because nothing was created. Only God existed.
Zombies have never existed before.
Yes. It existed before human beings did, or before the solar system.
No - Nothing existed before 'Biblical Times' except God.

yes. Earth was made before cavemen existed.
A:Modern humans have existed for over two hundred thousand years. Our distant hominid ancestors existed for millions of years before that.
Adam and Eve did not exist so the question is irrelevant
yes of course they did, they have existed for 100 years before that date.
Yes Jesus existed right from the start, he is ageless.
Yes - butter existed long before the 1930s - it was present long before the middle ages.
