Answer 1

1) State of matter
- Predicted to be a solid metal at room temperature. In practice seaborgium has only been made atom-by-atom in accelerator experiments, so bulk matter has never been produced.

2) Type of element
- Synthetic (man-made), radioactive transition metal — a transactinide in group 6 of the periodic table (symbol Sg, atomic number 106).

3) Who discovered seaborgium
- Independent teams at Lawrence Berkeley Laboratory (USA) and the Joint Institute for Nuclear Research (Dubna, then USSR) reported observations in the early 1970s; the discovery was contentious but credited to these laboratories.

4) Time and place it was discovered
- First reported in the early 1970s (both groups published claims in 1974). The work was done at Lawrence Berkeley Laboratory in Berkeley, California, and at the JINR facility in Dubna (Russia).

5) Three ways seaborgium is useful
- Purely scientific research:
1) Tests of heavy-element chemistry to see whether seaborgium behaves like lighter group‑6 elements (molybdenum, tungsten).
2) Probes relativistic and quantum effects in electronic structure of very heavy atoms.
3) Helps refine nuclear-reaction models and guides the synthesis of even heavier elements.
- (There are no practical commercial or industrial uses because of its extreme radioactivity and very short-lived isotopes.)

6) Physical properties
- Symbol: Sg, atomic number: 106, group: 6, period: 7.
- Predicted to be a dense, refractory transition metal and solid under normal conditions.
- Radioactive: only short-lived isotopes have been made; isotope half-lives range from milliseconds to seconds/minutes (no long-lived isotope exists).
- No bulk samples exist, so properties such as color, ductility, precise density, melting point and boiling point are not measured and are largely theoretical.

7) Chemical properties (flammability, corrosiveness, melting/freezing point)
- Flammability: not applicable in any practical sense — as a metal it would not be “flammable” like organic materials; experiments are limited to single atoms in controlled environments.
- Corrosiveness: typical metallic chemistry (expected to form oxides and higher oxidation states like +6), but bulk corrosivity is unknown because no macroscopic sample exists.
- Melting/freezing point: not measured experimentally. Predictions place it as a high‑melting refractory metal (similar to tungsten/molybdenum), but exact values are uncertain.
- Overall chemical behavior observed in trace experiments is broadly consistent with group‑6 chemistry (tendency toward +6 oxidation state), but data are limited.

8) One “unusable” fact about seaborgium
- It was named for living chemist Glenn T. Seaborg — one of the few elements named after a person who was still alive at the time the name was adopted.
