Phosphorus is more electronegative than sodium. The electronegativity of phosphorus is 2.19. The electronegativity of sodium is 0.93.

Chlorine is more electronegative than phosphorus. Generally, the trend of the periodic table is that electronegativity increases as you go from left to right, and it decreases as you go down.
Sodium has a larger atomic radius and is more metallic.
Oxygen is more electronegative than selenium.
Sulfur is more electronegative than hydrogen
Not sure if I understand your question correctly, but some elements are more electronegative than others, so they draw in electrons better than others. For example, in NaCl, chlorine (Cl) is much more electronegative than sodium (Na) so it simply takes the sodium's extra valence electron.
Chlorine is more electronegative than sodium. The farther right you move on the periodic table, the more electronegative elements are. Thus, noting that sodium and chlorine are on the same period, and chlorine is farther to the right than sodium, we know that chlorine is more electronegative than sodium
Aluminum is more electronegative than sodium. The electronegativity of aluminum is 1.61. The electronegativity of sodium is 0.93.
Chlorine is more electronegative than phosphorus. Generally, the trend of the periodic table is that electronegativity increases as you go from left to right, and it decreases as you go down.
According to the Pauling scale, the electronegativity of oxygen is 3.44 while that of phosphorus is 2.19. Therefore oxygen is more electronegative than phosphorus, i.e. the oxygen atom has a greater tendency to attract electrons towards itself than the phosphorus atom. Fluorine is the most electronegative element in the periodic table, with an electronegativity value of 3.98.
Much more electronegative than Sodium(Na).
Sodium has a larger atomic radius and is more metallic.
Sulfur is more electronegative than beryllium.
Iodine is lower in the halogen displacement series than bromine, i.e., iodine is less electronegative than bromine. However both chlorine and fluorine can displace bromine in sodium bromide, as they are more electronegative.
Oxygen is more electronegative than selenium.
Oxygen is more electronegative than hydrogen.
