Question

Which of the following statements are false? I. It takes less energy to add an electron to nitrogen than to carbon because nitrogen will be closer to achieving a noble gas configuration. II. It takes more energy to add an electron to fluorine than to oxygen because the radius of fluorine is smaller and more repulsion would occur in the p-orbitals. III. It takes more energy to add an electron to nitrogen than to carbon because of the extra repulsions that would occur in the 2p orbitals. IV. Less energy is released in adding an electron to iodine than to chlorine because the radius of iodine is larger a

Answer 1

Answer:

I and II

Explanation:

I. It will take more energy to add an electron to nitrogen than to carbon in order to achieve a noble gas configuration because nitrogen the outer shell (p-orbital) of nitrogen is filled with three electrons which will require alot of energy to add the required five electrons to achieve a noble gas configuration. Carbon on the other hand has four electrons in its outer shell which makes it more closer to achieving a noble gas configuration than nitrogen

II. The radius of flourine is not smaller compared to oxygen because fluorine has more electron than oxygen this makes its atomic radius increases due to the addition of energy shell.
