Answer:
C - show 7 neutrons in the nucleus
Explanation:
Use process of elimination:
-Answer A will not work because electrons are not in the nucleus.
-Answer B will change the atom's identity from nitrogen to fluorine; it will not work.
-Answer D will create a nitrogen ion, which is not what the prompt is asking for (an atom); it will not work.
The only logical answer is C, as that is the only one that is also true.
The pressure in a sealed container means the volume of container is fixed
so we cannot change the volume of container hence gas
The other factors which can affect the pressure are
a) moles of gas : if we increase the moles of gas the pressure of gas will increase
b) Temperature: if we increase the pressure of gas the pressure of gas will increase due to increase in kinetic energy
So the following cannot increase pressure
a) decrease in moles of gas
b) decrease in temperature of gas
The effective nuclear charge is the net positive charge experienced by valence electrons
