How do i rank the following elements by increasing electronegativity: sulfur, oxygen, neon, aluminum

aluminum, sulfur, oxygen, neon 

sulfur: 2.58 
oxygen: 3.44 
neon: 4.78 
aluminum 1.61 

Generally, electronegativity rises as you move left and up on the periodic table, with neon having the high

Because electrons have negligible mass, to account for the mass of the isotope, there must be 16 neutrons, 16 neutrally charged, massive, fundamental particles present in the sulfur nucleus. and thus finally, if we have the 32s2− ion, there are 18 electrons, 16 protons, and 16 neutrons.
