Electron affinity is the change in energy of an atom with a neutral charge when an electron is added to form an anion. A more negative electron affinity corresponds to a greater attraction for an electron. Electron affinity become less negative down a group and from left to right in the periodic table.The correct answer would be the large nonmetal atoms. Large nonmetals have a higher electron affinity than metals, meaning they are more likely to gain electrons than atoms with a lower electron affinity.
<span><span>Convert the percentages into decimals (you can do that by dividing the percent by 100), then multiply that by its
corresponding mass to find its relative amount/ contribution to the
atomic mass of chromium. After doing so, add all of the obtained values
together to get the average mass.

83.79% = .08379
9.50% = .095
4.35% = .0435
2.36% = .0236
Average mass of chromium = 0.8379(51.94) + 0.095( 52.94) + 0.0435(49.95) + 0.0236(53.94)

To get to Underworld, go out the exit on Three Dog's floor. Once you're outside, head straight ahead to the Abandoned Car Tunnels (there are a couple of Feral Ghouls in your way). Once inside the Abandoned Car Tunnels, look for the Brotherhood of Steel insignia and/or the words "To Mall Outpost" marked on the wall, and follow it. The same tunnels will also take you to Rivet City. Instead of getting out when you reach the Underworld "stop," you would continue heading south until you reach the end of the line.
and what does this have to do with chemistry
