Potassium's atomic number is 19, meaning it has 19 protons in its nucleus. In a neutral potassium atom, there are also 19 electrons orbiting the nucleus. The most common isotope of potassium, K-39, has 20 neutrons, giving it a total of 39 subatomic particles.
Protons are the subatomic particles represented by the atomic number of an element. The atomic number is equal to the number of protons in the nucleus of an atom, which determines the element's identity on the periodic table.
Subatomic particles are smaller than molecules and are the building blocks of atoms. Protons, neutrons, and electrons are examples of subatomic particles found in atoms. There are no known subatomic particles that are bigger than molecules.
Protons are the subatomic particles that give an atom its identity. The number of protons in the nucleus determines the element's atomic number, which in turn defines the specific type of atom.
In this case, the number 209 represents the sum of protons + neutrons.
Subatomic particles with no charges are neutrons

No, from 80 years.
Number of protons in the nucleus is the atomic number.
The total number of subatomic particles in the nucleus
No, sodium is not a subatomic particle. Sodium is a chemical element with the symbol Na and atomic number 11. Subatomic particles are particles smaller than an atom, such as protons, neutrons, and electrons.
The number of neutrons is different for isotopes.
Protons are the subatomic particles represented by the atomic number of an element. The atomic number is equal to the number of protons in the nucleus of an atom, which determines the element's identity on the periodic table.
An atom contain protons, neutrons and electrons. The number of these particles is different for each isotope.
The number of protons is equal to the atomic number of a chemical element.
