Help :) Which of the following statements about the nitrogen molecule is correct?
b. the bond takes places between two non metals
c. the bond is an example of non polar covalent
d. rearrangement of the electrons around each nitrogen must take place to comply with the octet rule ( I think this is correct)
e. all of the above are correct
Answer:
E = all of the above are correct
a) yes, there is a triple bond between the two nitrogen atoms
b) yes, both nitrogen atoms are nonmetals
c) yes, the bond is nonpolar covalent because the electronegativity values of the two nitrogen atoms are identical
d) yes, the electrons rearrange and combine to give each nitrogen atom an octet of valence electrons
E. All of the statements are correct.
E. all of the above
Triple bond because nitrogen is number 7. Two electrons in first level, five in the second. Each atom of the N2 molecule needs to share 3 electrons with the other atom.
Nitrogen is not a metal, so B is true.
C is true - sharing is covalent
D is true, as you said
So it's all of the above.
Yep, d) is correct. I used to know these folk that made the first twenty elements of the periodic table into a rhyme - you'd have to try saying it to yourself, phonetically is a broad hint! Nitrogen's a period two, group five. You'd be able to do all of this in your sleep and not have to fret about how to ask what to ask if you knew how to use the periodic table. It's like a road map of the elements. That said, I would make an educated guess seeing as how this is multiple choice but because I'm LAZY MINDED, not because it isn't possible to know this better and love it for its own sake, as sad as that is. It's a magnificent world, the chemical universe (sic).
Nitrogen has an oxidation number of five under certain circumstances. I'm just beginning to imagine you've been confused with all sort of complex thoughts about how atoms bond. Ionic bonding occurs to meet the octet rule (so does most covalent but you'll find funny idiosyncracies there that'll confuse you, I reckon, so...) I think it's a trick question, in short. I'm pretty sure the nitrogen atom travels around as N2, I know Nitrogen isn't considered a gas, I don't know that the element has a particular electronegativity and if it has an oxidation number of 5 under some circumstances (redox reactions, they're on my brain) it's possible the darned thing does have a triple bond. That's the best I can scrounge up becuase I DON'T KNOW but it's an example of Michael Faraday's wonderful work. The end.
P.S. I think it's e) - nitrogen also has an oxidation state of -3...which suggests a triple bond.
