Answer:
A well tested explanation of a natural phenomenon
Explanation:
A scientific theory is an explanation of a natural phenomenon which has been drawn from a well tested observation.
Theories are products of repeated scientific experiments. When a hypothesis otherwise known as a "scientific guess" survives a lot of scrutiny, we can elevate it to the status of a theory. Most theories starts off from simple observations. These observations can further spark series of experiments in such a field and a scientific guess proposed. Further testing and experimenting would now lead to a theory.
Answer:
is the isotopic notation of the atom
Explanation:
The isotope notation is:
![^a_bX](https://tex.z-dn.net/?f=%5Ea_bX)
<em>Where a is the mass number = Number of protons + Number of neutrons</em>
<em>b is atomic number = Number of protons</em>
The atomic number define the nature of the atom, the element with atomic number = 15 is phosphorus, P:
![^a_bP](https://tex.z-dn.net/?f=%5Ea_bP)
a = 15 protons + 16 neutrons = 31
b = 15
is the isotopic notation of the atom.
