Answer
Brief Explanations:
- Electronegativity is the ability of an atom in a chemical bond to attract electrons to itself. 2 - 10. Electronegativity generally increases across a period and decreases down a group in the periodic table. Using this trend and the positions of the elements in the periodic table, we can rank them.
- As you move from top to bottom within a group on the periodic table, electronegativity decreases. This is because the atomic radius increases down a group, so the out - ermost electrons are farther from the nucleus and less strongly attracted to it.
Answer:
- Electronegativity is the ability of an atom in a chemical bond to attract electrons to itself.
- Oxygen > Manganese > Germanium > Francium
- Selenium > Zinc > Vanadium > Titanium > Calcium
- Boron > Gallium > Indium > Thallium
- Polonium > Mercury > Tungsten > Barium
- Potassium < Aluminum < Carbon < Oxygen
- Lithium < Beryllium < Oxygen < Fluorine
- Lead < Tin < Germanium < Carbon
- Rubidium < Niobium < Silver < Xenon
- Aluminum < Sulfur < Oxygen < Neon
- Electronegativity decreases. Atomic radius increases, reducing electron - nucleus attraction.
