The atomic number
Technically, Wolverine never died. The element isn't on the periodic table. It is fictional and only exists in the Marvel Universe.
Oh jeez. Alright, water is a compound, not an element. The things that water is made of are on the periodic table, and that is hydrogen and oxygen. But since it is more than one element it is a compound. That is like asking why isn't dog on the periodic table.
No, never heard of it and can't find it in the periodic table of (all!) elements
No. Pyromanium is not an element. I have never even heard of it. you might want to check if pyromanium even exists.
The number of protons.
The number of protons in the nucleus never changes in a neutral atom. This is because the number of protons determines the element's identity.
The number of protons it has in the nucleus. Number of electrons and neutrons can vary but if the number of protons changes, you have a different element. Number of protons is a constant in an element which never changes.
No. Seaborgium is a synthetic element that has never been created in a large enough quantity to photograph.
The sugar and phosphate group of nucleotides never change. There are four possible nitrogenous bases and thus it is the only part of nucleotides that can change.
computer iscalled deligent and versatile machine because it never filltiared like human beings
You can't get one anywhere. But did you know that Chuck Norris' tears can cure cancer? Too bad he never cries.
The element number on the periodic table corresponds to the number of protons in the nucleus of an atom of that particular element. This number is also known as the atomic number and defines the identity of the element. Elements are arranged on the periodic table in order of increasing atomic number.
