I assume you are asking what part of an element will always be the same, regardless of ionization or various isotopes. This would be the proton.
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.
Bromine belongs to the same family as chlorine and fluorine. They are all part of the halogen group on the periodic table.
All atoms of the same element have the same number of protons, which is its atomic number. A neutral atom will have the same number of electrons as protons.
Atoms of the same element that have different masses are called isotopes of the element. The presence of different numbers of neutrons in the nucleus is responsible for the existence of isotopes of an element.
The element that would have properties most similar to the new element would be an element that lies in the same group as the new element. Specifically, the element with the most similar properties will lie directly above or below that element in the group.

Number of protons.
A single proton (not part of a larger nucleus) is the same as a positive hydrogen ion.
An element is made by atoms. smallest part of element is atom.
Element is a part or aspect of something abstract, esp. one that is essential or characteristic. You may hear the word element alot in chemistry, such as the element Iron. This means that it is all the same types of atoms.
Bromine belongs to the same family as chlorine and fluorine. They are all part of the halogen group on the periodic table.
atom is the smallest part of element
No, isotopes of the same element are of different weight.
Atoms of the same element are alike in terms of their number of protons, which determines the element. However, atoms of the same element can differ in the number of neutrons they contain, leading to different isotopes of that element.
Restate the question: it makes no sense; same element as what?
No. Atoms of the same element have the same chemical properties.
They may come from different isotopes of the same element, but not from the same atom.
