Why does electronegativity decrease down a group on the periodic table?
Why does electronegativity decrease down a group on the periodic table?
- The radioactive nature of elements in period 7.
- The gain of electrons that occupy energy shells closer to the nucleus.
- The full outer shells of noble gases.
- The presence of more electron shells between the nucleus and the outermost electrons. (correct)
How does the number of electron shells affect nuclear shielding?
How does the number of electron shells affect nuclear shielding?
- More electron shells increase shielding. (correct)
- More electron shells result in decreased shielding.
- Fewer electron shells increase shielding.
- Fewer electron shells have no effect on shielding.
Why do noble gases have electronegativity values of 0.0?
Why do noble gases have electronegativity values of 0.0?
- Because they are in period 7 of the periodic table.
- Due to the presence of radioactive isotopes.
- Because they have full outer shells of electrons. (correct)
- Because they have a high number of valence electrons.
