Rank the following elements by electron affinity, from most positive to most negative ea value:
tellurium, bismuth, neon, sodium, iodine i tried te, bi, na, i, ne and it was incorrect.

Explanation:

When an electron is added to a neutral atom to convert it into a negative ion then the amount of change taking place in its energy is known as electron affinity.

Smaller is the size of an atom more readily an electron will be gain an electron because of strong force of attraction exerted by its nucleus towards the electron.

Out of the given options iodine is the smallest in size and neon being a noble gas will be highly stabilized. Hence, neon will have zero electron affinity.

Therefore, we can conclude that given elements are ranked from most positive to most negative EA value as follows.

               Ne < Na < Bi < Te < I

answer; the numbers of valence electrons in the acetic acid molecule (ch3co2h) is 24;
