No. of electrons and no. of protons are equal to atomic no.
Since, protons are positively charged and electrons are negatively charged They cancel
each other's charge and hence, the atom is neutral as a whole.

Which particle determines the atomic number of an element?
The atomic number of an element is determined by the number of protons.
Which two particles does the atomic mass number represent?
The sum of Protons and neutrons
What is the number of atomic particles in chlorine?
A chlorine-35 atom has 17 protons, 17 electrons and 18 neutrons, altogether 52 atomic particles. Chlorine-37 has two more neutrons and it has 54 atomic particles.
Which are the two important particles in an isotope?
The atomic particles of an isotope are the proton, electron and neutron
What two elements make up the atomic number?
All the elements have an atomic number. The atomic number is the number of protons found in the atom of a certain element. And to equalize themselves the atoms will usually have the same amount of electrons as protons so electrons also equal the atomic number. The atomic number is the number on the top of the box on the periodic table for each element. You must have been asking what two subatomic particles make up the atomic number. In that case it would be the proton and the electron because the neutron is so mall that chemist's usually nullify it.
What two subatomic particles match the atomic number on the periodic table?
The two subatomic particles are protons and electrons. They match the atomic number on periodic table.
Which two atomic particles have equal but opposite charge?
Electrons and protons (subatomic particles).
The atomic number is the same as the number of what two particles?
protons and electrons
Which particle determines the atomic number of an element?
The atomic number of an element is determined by the number of protons.
The atomic number is the same as the number of these two particles?
The "Atomic number" of an element corresponds to the number of only the protons in the nucleus of its atoms. Add to that the number of neutrons that are also in there, and you have the "Atomic weight".
Which two particles does the atomic mass number represent?
The sum of Protons and neutrons
What is the number of atomic particles in chlorine?
A chlorine-35 atom has 17 protons, 17 electrons and 18 neutrons, altogether 52 atomic particles. Chlorine-37 has two more neutrons and it has 54 atomic particles.
Which are the two important particles in an isotope?
The atomic particles of an isotope are the proton, electron and neutron
What happend to the atomic number of an element which emits alpha particle and two beta particle?
THe atomic number would decrease by 2 as alpha particle comes out. But for two beta particles the atomic number would increase by 2. So the atomic number remains unchanged due to emission of one alpha followed by 2 beta particles.
Which two particles in an atom are equal of in number?
protons and electrons.
Which two particles in a atom are equal in number?
Electrons and protons.
An atomic number is equal to?
The atomic number is equal to the number of protons in the nucleus of an atom of that element. For example, oxygen has eight protons in its nucleus, helium has two, and hydrogen has one.
