Phosphorus can be stable with 12 electrons in its valence structure while nitrogen can never have more than 8 electrons in its v
dolphi86 [110]

Here we have explain that the maximum possible electrons present in nitrogen valence shell is 8 whereas in phosphorous 12 valence electrons are present.

Although both nitrogen (N) and phosphorous (P) belongs to the same series there are several properties which are different between both the element. The number of electrons present in nitrogen is seven which are present in the -s and -p orbitals. The electronic configuration of nitrogen is 1s²2s²2p³. In which the outermost electrons are the valence electrons i.e. 5 valence electrons are present. The maximum orbitals are possible under the principal quantum number 2 are -s and -p orbitals. Now the maximum capacity of the p orbital to contain 6 electrons, as it is half filled in nitrogen another 3 electrons can be incorporated. Thus the maximum number of electrons can be present in nitrogen is 10 among which 8 is the valence electrons.

On the other hand there are 15 electrons in phosphorous the electronic configuration is 1s²2s²2p⁶3s²3p³. Now the principal quantum number 3 can have three orbitals -s, -p and -d. So another 13 electrons can be incorporated (3 in -p orbital and 10 in -d orbital) among which upto 12 electrons can be its valence electrons.

arsen [322]
<h3><u>Answer</u>;</h3>

a. 3 molecules 3 carbon

b. 6 molecules 18 carbon

c. 6 molecules 18 carbon

d. 5 molecules 15 carbon

e. 3 molecules 15 carbon

f. 3 molecules 15 carbon

<h3><u>Explanation</u>;</h3>
  • In the Calvin cycle, carbon atoms from CO2 are ncorporated into organic molecules and then  used to build three-carbon sugars, a process that is fueled by, and dependent on, ATP and NADPH from the light reactions.
  • Calvin cycle take place in the stroma. Reactions of Calvin cycle are divided into three main stages: carbon fixation, reduction, and regeneration of the starting molecule.
  • During carbon fixation, a CO2 molecule combines with a five carbon acceptor molecule ribulose-1,5-bisphosphate. The result is a six carbon compound that splits to two three carbon compound, 3-PGA.
  • During reduction; ATP and NADPH are used to convert the 3-PGA molecules into molecules of a three-carbon sugar, glyceraldehyde-3-phosphate.
  • Finally during regeneration, some G3P molecules are used to make glucose while others are recycled to regenerate RuBP acceptor.

larisa [96]
A barometer is a tool, not a variable. A barometer measures barometric or air pressure, which is a variable that meteorologists use to predict the weather.
