Use a periodic table to rank the following elements from Greatest Electronegativity to Least Electronegativity. (Highest to lowest)

Question

Chlorine, Barium, Selenium, Francium

Answer 1

To rank the elements (Chlorine, Barium, Selenium, and Francium) from greatest to least electronegativity, we first need to know their electronegativity values:

1. Chlorine (Cl) - High electronegativity (around 3.16)
2. Selenium (Se) - Moderate electronegativity (around 2.55)
3. Barium (Ba) - Low electronegativity (around 0.89)
4. Francium (Fr) - Very low electronegativity (predicted around 0.7, but it is highly radioactive and its properties are not very well understood)

Ranking these from greatest to least electronegativity:

1. Chlorine (Cl) - Highest
2. Selenium (Se)
3. Barium (Ba)
4. Francium (Fr) - Lowest

So the final order is:

1. Chlorine (Cl)
2. Selenium (Se)
3. Barium (Ba)
4. Francium (Fr)
