Final answer:
All the atoms mentioned (calcium, gold, argon, iodine) belong to different elements with unique properties. Calcium and argon have the same atomic mass and electron configuration, while gold and iodine have different properties due to their different atomic structures. Atoms of different elements can have similarities in terms of electron configuration or atomic mass, but overall they have distinct properties and characteristics.
Step-by-step explanation:
All the atoms mentioned (calcium, gold, argon, iodine) belong to different elements with unique properties.
Calcium and argon have the same atomic mass and electron configuration, while gold and iodine have different properties due to their different atomic structures.
It is important to note that atoms of different elements can have similarities in terms of electron configuration or atomic mass, but overall they have distinct properties and characteristics.
