Question

1. what elements are a gas at a given temperature? hydrogen, helium, nitrogen, oxygen. 2. what elements are noble gases? 3. hover the cursor over magnesium, mg, what type of specific information is given about the element in the enlarged information area? (list 5) 4. now click on the name magnesium on the left tab. write three pieces of information given. 5. what are the element symbols for the metalloid elements? 6. what is the symbol and atomic number of the element with the most protons according to this periodic table? click on its name to find out what year it was discovered.

Explanation:

1. Noble gases are helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn).
2. When hovering over magnesium (Mg) in a periodic - table information area, common details include atomic number (12), atomic mass (approx. 24.31), symbol (Mg), element type (metal), and electron configuration.
3. Clicking on magnesium in a left - tab might show its melting point, boiling point, and density.
4. Metalloid elements and their symbols: boron (B), silicon (Si), germanium (Ge), arsenic (As), antimony (Sb), tellurium (Te), polonium (Po), astatine (At).
5. The element with the most protons in a typical periodic table is oganesson (Og) with an atomic number of 118.

Answer:

1. Helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), radon (Rn).
2. Atomic number, atomic mass, symbol, element type, electron configuration.
3. Melting point, boiling point, density.
4. B, Si, Ge, As, Sb, Te, Po, At.
5. Symbol: Og; Atomic number: 118.
