From the trends you have seen, it is likely to be a dark coloured solid with a melting point higher than iodine and a molecule At 2. It will be the least reactive element in the group, and not a very good oxidising agent. If it reacts with, say, sodium it will form an ionic salt NaAt.

WebTrend of melting point down the group. The boiling point of group 17 elements steadily increase with atomic number. Trend of boiling point down the group. All halogens are coloured. This is due to absorption of radiations in visible region which results in the excitation of outer electrons to higher energy level. WebThe zero point is different: temperature (K) = temperature (°C) + 273.15. Thus, the melting point of water is = 0°C = 273.15 K and the boiling point of water is = 100°C = 373.15 K. On the Fahrenheit scale (°F), the …
