You can determine if the group belongs to the groups you already studied by comparing the boiling and melting point of the new elements with the ones you already know.
Elements are grouped in the periodic table based on specific properties. These properties include the boiling and the melting point.
- Boiling point: Temperature at which a liquid starts evaporating.
- Melting point: Temperature at which the solid-liquid change occurs.
Moreover, these properties are often constant which means every element has a specific boiling and melting point and you can identify elements based on this.
According to the above, you need to compare the boiling and melting point given ( −185°C and -190°C) to the ones you previously studied. In this situation, there are two possibilities:
- You find an element with identical temperatures for the boiling and melting points: This element and the new one are the same
- You find none of the previous elements has similar boiling and melting points: This is a new element.
Note: This question is incomplete because the elements of the previous activity are not given; due to this, I answered based on previous knowledge.
