Which choice correctly describes the properties and atomic structure of the element Potassium (K)?
Responses
Potassium is very reactive non metal with 19 electrons
Potassium is very reactive non metal with 19 electrons
Potassium is a non reactive metal with 19 neutrons
Potassium is a non reactive metal with 19 neutrons
Potassium is a very reactive non metal with 39 protons
Potassium is a very reactive non metal with 39 protons
Potassium is a very reactive metal with 19 protons
Potassium is a very reactive metal with 19 protons
To determine the correct choice, we need to know the properties and atomic structure of Potassium (K).
First, let's look at the properties of Potassium. Potassium is a metal that is actually quite reactive, especially with water. It is not a nonmetal because it is a metal. Therefore, we can eliminate the choices that describe Potassium as a nonmetal.
Next, let's consider the atomic structure of Potassium. Potassium, with the symbol K, has an atomic number of 19. The atomic number indicates the number of protons in the nucleus of an atom. Therefore, Potassium has 19 protons.
Neutrons, on the other hand, are not determined by the atomic number but by the atomic mass. However, the choices do not provide information about the atomic mass of Potassium, so we cannot determine the exact number of neutrons.
Based on the information we have, the correct choice is:
"Potassium is a very reactive metal with 19 protons"
