Nitrogen vs Oxygen
(Compare and Contrast)
Compare
to examine the character or qualities of especially in order to discover resemblances or differences or to respresent as simillar
Contrast
to compare in order to show unlikeness or differences; note the opposite natures, purpose, etc of:
Bubble Maps
used to describe qualities using adjectives ("sparkle words") and adjectives phrases. As a writing tool it enriches students' abilities to identify qualities and use descriptive words. In the center circle, write the word or thing being described.

Differences
1. Symbol
The symbol of Nitrogen is N and the
symbol for Oxygen is O.
2. Group
Nitrogen group VI A while Oxygen group
VII A.
3. Valence Electrons
Nitrogen has five
electrons in its outer most orbit (orbit 2). Oxygen has six electrons in
its outer most orbit (orbit 2).
4. Atomic Number
Nitrogen has an
atomic number of seven, and Oxygen has an atomic number of eight.
5. Atomic Mass
Nitrogen = 14.01 and Oxygen = 16.
6. Electronegativity
Nitrogen = 3.04 and Oxygen = 3.44.
7. Reactivity
Nitrogen is inert while oxygen is
highly reactive so a spark anywhere near liquid oxygen is extremely dangerous
if other flammables are anywhere near.
8. Abundance on air
There is more of
nitrogen in the earth's air than oxygen. Nitrogen
makes up most of our breatheable air 75%. Oxygen only makes up
25% of our air.
9. Harmness
Nitrogen if breath out
in large amount may harm and oxygen never harms.
Similarities
1. Phase
Both are gasses at
room temperature
2. Period
Both are on the second period in
periodic table.
3. Diatomic molecule
Both form diatomic
molecules (ie O2 N2 H2 Cl2)
4. Involved in organic chemistry
Both are involved in
organic chemistry (ie organic chemistry mainly considers H, C, O, N, S, P, Cl,
Br, I)
5. Helpful to tires
Nitrogen and Oxygen are helpful to
filled tires.
How tips on making double bubble maps ?
BalasHapusHere are the tips :
Hapus1. Think of the 2 elements you want to compare.
2. Make 2 pieces of bubble in Microsoft Office, Power point, Adobe photoshop or drawing paper.
3. Give bubble a different color.
4. Write the differences to the 2 elements in each bubble.
5. Write the similarities to the 2 elements in the slice of the bubble.
6. Finish.
Why Nitrogen in the air calculate more than Oxygen ? Any reason ? Explain please.
BalasHapusCompared to O, N is 4 times as abundant in the atmosphere. However, we must also consider the relative abundances of O and N over the entire Earth (oxygen is about 10,000 times more abundant). Oxygen is a major component of the solid earth, along with Si and elements such as Mg, Ca and Na.
HapusNitrogen is not stable as a part of a crystal lattice, so it is not incorporated into the solid Earth. This is one reason why nitrogen is so enriched in the atmosphere relative to oxygen.
The other primary reason is that, unlike oxygen, nitrogen is very stable in the atmosphere and is not involved to a great extent in chemical reactions that occur there. Thus, over geological time, it has built up in the atmosphere to a much greater extent than oxygen.
N and O are found in the living biosphere and fossil organic matter (and both are soluble in sea water too). But, only a small fraction (less than 1% for N and much, much less than 1% for O) of the total for these element on the planet are to be found in these places.
Hope you got your answer.
Thank you.
Why oxygen in nature is so much
BalasHapusI thought you were miss understood.
HapusIt has said from the text that Nitrogen are more than Oxygen in air (atmosphere). The primary reason is that, unlike Oxygen, Nitrogen is very stable in the atmosphere and is not involved to a great extent in chemical reactions that occur there. Thus, over geological time, it has built up in the atmosphere to a much greater extent than Oxygen.
What is the character of the two elements?
BalasHapusCharacteristics:
Hapus1. Nitrogen
Nitrogen is a colorless, odorless, tasteless, diatomic and generally inert gas at standard temperature and pressure. At atmospheric pressure, nitrogen is liquid between 63 K and 77 K. Liquids colder than this are considerably more expensive to make than liquid nitrogen is.
2. Oxygen
Oxygen in its common form (O2) is a colorless, odorless and tasteless diatomic gas. Oxygen is extremely reactive and forms oxides with nearly all other elements except noble gases.
Earth's atmosphere at first contained no free oxygen. It only contains free oxygen now because green plants - not initially present on Earth - produce it during photosynthesis.
If green plants were to disappear, all the oxygen in Earth's atmosphere would react over a period of time and the atmosphere would once again contain no free oxygen. If we discover any other planets with atmospheres rich in oxygen, we will be able to infer that life is almost certainly present on these planets.
Liquid and solid oxygen are pale blue and are strongly paramagnetic.
Ozone (O3), another form (allotrope) of oxygen, occurs naturally in the Earth's upper atmosphere.
The reaction with oxygen is one of the critera we use to distinguish between metals (these form basic oxides) and non-metals (these form acidic oxides).
