Atoms are electrically neutral. The number electrons and number of protons in neutral atoms are same. The number of neutrons in some atoms are same as the number of protons. Example: Calcium atom contains 20 protons and 20 neutrons.
But some atoms contain same number of protons but different number of neutrons. For example carbon atoms exist in three forms - all contain 6 protons but some contain 6 neutrons, some 7 neutrons and others with 8 neutrons. These type of atoms are known as isotopes
Definition of isotope: Atoms with same number of protons but different number of neutrons
It shows that the different number of neutrons determines the existence of isotopes.

What else can I help you with?
What particle does the atomic number equal in the nucleus?
The number of Protons in the nucleus determines the atom's Atomic number.
What sub atomic particle determines what the element is?
The number of protons in the atomic nucleus determines what element it is. Each element has a unique number of protons, known as its atomic number.
What is the nucleus of an isotope with a certain atomic mass and number?
The nucleus of an isotope with a specific atomic mass and number contains protons and neutrons. The number of protons determines the element, while the sum of protons and neutrons gives the atomic mass. The neutrons in the nucleus help stabilize it by balancing the repulsion between positively charged protons.
What happens to a radioisotope when it undergoes alpha emission?
During alpha emission, a radioisotope emits an alpha particle, which is composed of two protons and two neutrons. This reduces the atomic number of the parent isotope by 2 and the atomic mass by 4. The emission of an alpha particle transforms the parent isotope into a new element.
How do you determine the isotope?
Isotopes are determined by the number of neutrons in an atom's nucleus. Each isotope of an element has the same number of protons in its nucleus but a different number of neutrons. Isotopes of an element have the same chemical properties but different atomic masses.
What atomic particle determines the isotope of an element?
The number of neutrons.
What particle will be emitted probably by an isotope with an atomic number greater than 83?
An Alpha particle
What is the sub atomic particle that varies from one isotope to another?
It is neutron
What is the positive subatomic particle that determines the atomic number of a substance?
proton
What particle does the atomic number equal in the nucleus?
The number of Protons in the nucleus determines the atom's Atomic number.
What sub atomic particle determines what the element is?
The number of protons in the atomic nucleus determines what element it is. Each element has a unique number of protons, known as its atomic number.
What subatomic particle determines if an element is an isotope or not?
The neutron; the proton determines the element of the atom, but different atoms of the same element can have different atomic masses, due to the different number of neutrons of the atoms. Atoms of same element having same number of protons but different number of neutrons are called Isotopes. Thus, neutron determines the isotope of an atom.
What is the nucleus of an isotope with a certain atomic mass and number?
The nucleus of an isotope with a specific atomic mass and number contains protons and neutrons. The number of protons determines the element, while the sum of protons and neutrons gives the atomic mass. The neutrons in the nucleus help stabilize it by balancing the repulsion between positively charged protons.
Identify the subatomic particle used to define an element and explain why this particle is used.?
no i cant answer it
What has an atomic mass of 3?
Tritium, an isotope of hydrogen, or Helium-3 (which does not have a specific name).
What happens to a radioisotope when it undergoes alpha emission?
During alpha emission, a radioisotope emits an alpha particle, which is composed of two protons and two neutrons. This reduces the atomic number of the parent isotope by 2 and the atomic mass by 4. The emission of an alpha particle transforms the parent isotope into a new element.
If the isotope bismuth-213 emits an alpha particle two protons and two neutrons which element will be left over?
Lead-209 will be left over after the isotope bismuth-213 undergoes alpha decay, as the emission of an alpha particle causes the atomic number of the element to decrease by 2. Bismuth-213 has an atomic number of 83, so after the emission of an alpha particle (which has an atomic number of 2), the resulting element will have an atomic number of 81, which corresponds to lead.
