Question

1. what elements are a gas at a given temperature?helium, neon, argon, krypton, xenon, radon 2. what elements are noble gases? atomic number atomic mass symbol elemnt type electron configuratio 3. hover the cursor over magnesium, mg, what type of specific information is given about the element in the enlarged information area? (list 5) metal point, boiling point, density 4. now click on the name magnesium on the left tab. write three pieces of information given. b, si, ge, as, e, po, al

Explanation:

1. Helium, neon, argon, krypton, xenon, and radon are noble - gases which are gases at standard conditions.
2. Noble gases include helium (He, atomic number 2), neon (Ne, atomic number 10), argon (Ar, atomic number 18), krypton (Kr, atomic number 36), xenon (Xe, atomic number 54), radon (Rn, atomic number 86). Their electron configurations are stable with full outer - shells.
3. For magnesium, common properties listed could be melting point, boiling point, density, atomic mass, atomic number.
4. Without clear context on the "B, si, ge, as, te, po, at", assuming it's about element properties, possible information could be atomic number, atomic mass, electron configuration.

Answer:

1. Helium, neon, argon, krypton, xenon, radon
2. Helium (He, atomic number 2), neon (Ne, atomic number 10), argon (Ar, atomic number 18), krypton (Kr, atomic number 36), xenon (Xe, atomic number 54), radon (Rn, atomic number 86)
3. Melting point, boiling point, density, atomic mass, atomic number
4. Atomic number, atomic mass, electron configuration
