Atomic number is defined as the number of protons or number of electrons.
Atoms having same number of protons are same. From the given models, Model 1, 2 and 4 have 2 protons with different neutrons. Hence, these models belong to same element.

What is Cladogram?
- In cladistics, a cladogram is a diagram that is used to depict relationships between species.
- Cladograms reconstruct the taxa's evolutionary history (phylogeny) by showing these links. Phylogenies and trees are other names for cladograms.
- A cladogram's root, clades, and nodes are its most important components. The root is the first ancestor shared by all groups that branched off from it. The branches that represent related groups and their shared ancestors are known as clades. The points known as nodes represent the fictitious ancestors.
