Answer:
p orbital.
Explanation:
Valence electrons are the electrons in an atom holding the very last orbital which is used in chemical bonding with other elements. Their existence could define the chemical properties of that atom.
During the first energy in ionization of an N2 molecule the molecular orbital from which the electron could be extracted is the only one with the highest energy level. Nitrogen has its outermost orbital (p) containing three valence electrons. Each orbital is only half filled, and thus it is unstable Thus, the electron mission must have been removed from p orbital.
The decay curve is a graph showing the relationship of the amount of a substance like Phosphorus-32 with respect to time. Through time, the amount decreases. If the curve was given, you will just have to locate the half of the original amount in the y-axis and connect it to the curve. Then, you move it downwards to the x-axis to determine the time. The time at which the amount of Phosphorus-32 left is reduced to half is called the half-life.
But this have been experimented and there is already an empirical value for this. The half-life of Phosphorus-32 is 14.29 days.
28.0 x 0.6424 = 18
25.0 x .6424 = 16.1
Mass = 34.1
