What is the subatomic particle and the calculation derived from it that is not found in the periodic table?

Subatomic particles are protons, neutrons and electrons; the number of protons and electrons (in the neutral state) are equal to the atomic number of an element.


How do you calculate subatomic particles in isotopes?

To calculate the number of subatomic particles in isotopes, you need to know the atomic number (number of protons) and mass number (sum of protons and neutrons) of the isotope. Subtract the atomic number from the mass number to find the number of neutrons. The number of electrons will be equal to the number of protons if the atom is neutral.


How do isotopes of the same element differ with regards to subatomic particles?

Same number of protons; different number of neutrons. The number of electrons will also be the same, assuming a neutral atom.

Number of subatomic particles in potassium?

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.


What is the number of subatomic particles for oxygen?

What is the subatomic particles on which the atomic number is based?

Number of protons in the nucleus is the atomic number.


Is sodium a subatomic particle?

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.


What does the mass number equal?

What two subatomic particles match the atomic number on the periodic table?

Protons and electrons match the atomic number on the periodic table. The atomic number represents the number of protons in an atom, which also determines its chemical identity. Electrons balance the positive charge of protons in an atom, making it electrically neutral.


What is the isotopes in the subatomic particles?

The number of neutrons is different for isotopes.
