Answer: Structural Isomers
Explanation:
The compounds having similar molecular formula but different arrangement of atoms or groups in space are called isomers and the phenomenon is called as isomerism.
Isomers are of two types: structural isomers and stereo isomers.
Structural isomers are isomers in which molecules with the same molecular formula have different bonding patterns.
Stereoisomers are isomers in which molecules have the same molecular formula and sequence of bonded atoms but differ in the three-dimensional orientations of their atoms in space.
Thus when molecules have the same number of each element but those atoms are arranged differently they are known as Structural isomers.
The mass number is the sum of the protons and neutrons in an atom. 235-92 = 143 neutrons.
Element 92 is Uranium.
Uranium is also the highest atomic number element which exists in nature. All of the rest above element 92 only exist nuclear high-energy reactions (the transuranium elements), and most experience nuclear decay very quickly and form other elements with fewer protons.
