Which of the following atomic elements does not belong in the following list?

In summary, Greg Bernhardt said that the elements that do not belong in the list are Carbon, Neon, Silicon, Phosphorus, Iodine, and Xenon. They were all named by their discoverers, except for Carbon which had been known since ancient times. Iodine is the only one that does not fit because its the only one you can spell with the atomic symbols.

this may not be what you are looking for but Carbon is an exception in being the only one that does not have a full shell of 8 in its electron structure

It goes 2-4
and the others go 2-8-something-...

Silcon is semi-metallic, the rest are non-metallic.
 
  • #4
Phosphorus

The others can be found in a pure state, but phosphorus is too reactive and has be be separated?

Those answers are right, but not what I am looking for. I am looking for an answer that is not scientific, more language based.

They all contain the letter 'n' 'cept P.?
 
  • #7
The only other thig I can think of is that they were all named by they're discoverers except Carbon which had been known since ancient times?
 
  • #8
neither is silicon tho'
 
  • #9
for whatever reason, carbon
Greg just asked which element doesn't belong, not why:wink:

I will hazard a guess. (just a guess...don't kill me ):

Phosphorus

Because the word is derived from two words ( phos (light) and phoros (bearer))
instead of from one word like the others.

He said it was language-based...

neon - it is the only one that isn't next to another element in the list

Holy moly, i think i got it:

Iodine is the one that doesn't fit

Reason:

Its the only one you can spell with the atomic symbols


C-Ar-B-O-N
Ne-O-N
Si-Li-C-O-N
P-H-O-S-P-H-O-Ru-S
Xe-N-O-N

Dude, i got too much time on my hands!

dduardo gets the point!
 

1. What are the atomic elements included in the list?

The list includes hydrogen, oxygen, nitrogen, carbon, and iron.

2. Why does one of these elements not belong in the list?

The element iron does not belong in the list because it is a transition metal, while the other elements are nonmetals.

3. How are these elements different from each other?

Hydrogen, oxygen, nitrogen, and carbon are all nonmetals and are found in the upper right corner of the periodic table. Iron, on the other hand, is a transition metal and is found in the middle of the periodic table.

4. What are the properties of these elements?

Hydrogen is a colorless gas and the lightest element. Oxygen is a highly reactive gas and is essential for life. Nitrogen is a colorless and odorless gas and makes up about 78% of the Earth's atmosphere. Carbon is a versatile element that is found in all living organisms. Iron is a strong, ductile, and magnetic metal.

5. How are these elements used in everyday life?

Hydrogen is used in the production of ammonia and in fuel cells. Oxygen is used in medical treatments, welding, and combustion. Nitrogen is used in fertilizer production and as an inert gas in packaging. Carbon is used in the production of steel and as a key component in many compounds. Iron is used in the production of steel and in various industrial applications.
