5. When the students discovered it, did they find a solid, a liquid, or a gas? Explain your

reasoning

The students must have found Boron as a solid.

Explanation:

Boron is a group 3 element that is known to be in its solid state at room temperature.

Infact, the melting point of Boron is known to be very high (2076°C) and its boiling point, even higher (3927°C).

So, it is logical that the temperature the students work with is within the range below 2076°C and hence, will have Boron in its solid state.

Note that Boron is a group 3 element, a metalloid (properties between a metal and a non-metal) with very high melting and boiling points.

Hence, it is easy to see why the Boron discovered has to be in its solid form.
