Sure! Let's break down the clues given:
1. An element belongs to group 17 of the periodic table.
2. We're asked about the likely type of this element.
3. We're also asked about the appearance of a solid sample of this element.

Group 17 of the periodic table is known as the Halogen group. The elements in this group are:
- Fluorine (F)
- Chlorine (Cl)
- Bromine (Br)
- Iodine (I)
- Astatine (At)

Halogens are known for their distinct physical states and appearances:
- Fluorine: Pale yellow gas
- Chlorine: Yellow-green gas
- Bromine: Dark red liquid
- Iodine: Shiny purple-black solid
- Astatine: Likely metalloid with dark or shiny appearance

Given this, the characteristic type of an element in group 17 is a halogen.

Next, for the appearance of a solid sample, we need to consider the solid elements in this group. Both iodine and astatine fit this criterion. The common characteristic for a solid halogen is that it would have a shiny or dark appearance.

Thus, the answers are:

1. An element belongs to group 17 of the periodic table. This element is most likely a halogen.
2. A solid sample of this element would have a shiny or dark appearance.
