The answer depends on the atom! The total number of subatomic particles in an atom of an isotope is the sum of the mass number and the atomic number of the isotope; the mass number counts the protons and neutrons together, and the atomic number recounts the number of protons, which in a neutral atom must be the same as the number of protons.

What particles are never present in an atom?
molecules.
What is the total number of subatomic particles in one atom of scandium?
21p+21e+24n=66
What is the total number of subatomic particles in the nucleus of an atom bi?
In this case, the number 209 represents the sum of protons + neutrons.
Which to particles in an atom are equal in number?
The protons and electrons are equal in number in a neutral atom
What two particles in an atom always have the same number?
In a neutral atom, the number of protons is equal to the number of electrons.
Protrons are particles that are?
Protons are the positively charged particles that are present in the nucleus of the atom and their number determines the atomic number of the atom.
What are the particles that make a atom including the atomic number and mass number?
The atomic number is the number of protons in an atom (which equal the number of electrons present) The atomic mass is the number of protons+neutrons in an atom
Total number of particles in the nucleus is called what?
There are two types of particles in the nucleus of an atom, which are the Protons and the Neutrons. The number of particles in the nucleus depends what is the element. For example, Oxygen has 8 protons and 8 neutrons in the nucleus and Phosphorus has 15 protons and 16 neutrons in the nucleus.
What particles are never present in an atom?
molecules.
What is the total number of subatomic particles in one atom of scandium?
21p+21e+24n=66
What would be the total number of electrons present in a theoretical atom of Uuo-291?
The number of electrons will be 118.
What is the number of subatomic particles are in an atom?
An atom contain protons, neutrons and electrons. The number of these particles is different for each isotope.
Would you use atomic number or mass number or both to obtain the number of particles in an atom?
atomic number is the total number of protons OR electrons in an atom. mass number is the total sum of number of protons and neutrons. atomic number subtracted from mass number gives the number of neutrons in an atom. Mass number - atomic number = number of neutrons.
What is the total number of subatomic particles in the nucleus of an atom bi?
In this case, the number 209 represents the sum of protons + neutrons.
Which to particles in an atom are equal in number?
The protons and electrons are equal in number in a neutral atom
How many subatomic particles are present in an atom except proton neutron electron and what are they?
The only subatomic particles that exist in an atom are protons, neutrons, and electrons.
What are positive particles in the atom?
Protons are the positively charged particles found in the nucleus of the atom.
