Question

question 9 (1 point) q9 - find the liquid in group 17 mercury tungsten osmium bromine question 10 (1 point) q10 - find the transuranium element with the lowest atomic mass uranium thallium neptunium plutonium

Explanation:

For Question 9, group 17 elements are halogens. Bromine is the only liquid among the halogens at room - temperature. Mercury is in group 12, tungsten in group 6 and osmium in group 8. For Question 10, transuranium elements are those with atomic number greater than 92 (uranium). Neptunium (atomic number 93) has the lowest atomic mass among common transuranium elements compared to plutonium. Uranium is not a transuranium element and thallium has an atomic number less than 92.

Answer:

Question 9: D. Bromine
Question 10: C. Neptunium
