An atom of an element that differs in the number of neutrons compared with other atoms in the same element is called an isotope. Isotopes have the same number of protons and electrons but different numbers of neutrons, resulting in variations in Atomic Mass.
An isotope differs from its parent element in the number of neutrons in its nucleus, which can affect its stability and properties.
They are both Isotopes of Barium. The 56 protons tell us that the element is Barium and when you add the neutrons with the protons you get barium138 and barium134. They are both stable isotobes of barium but of all the barium in the world about 72% is barium138 and 2% is barium134.
neutrons
Isotopesare variants of atoms of a particular chemical element, which have differing numbers of neutrons. Atoms of a particular element by definition must contain the same number of protons but may have a distinct number of neutrons which differs from atom to atom, without changing the designation of the atom as a particular element.
To determine the number of neutrons, subtract the atomic number from the mass number. In this case, 208 - 83 = 125 neutrons.
An isotope
This atom is called isotope.
the atom is an isotope
An isotope differs from its parent element in the number of neutrons in its nucleus, which can affect its stability and properties.
Atoms of the same element with varying numbers of neutrons are isotopes.
Neutrons
The number of neutrons in an isotope differs, leading to variations in mass number. Isotopes of an element have the same number of protons (atomic number) but different numbers of neutrons.
an isotope
Is called an Isotope.
neutrons in its nucleus, compared to the standard number of neutrons for that element. This difference in neutron number gives each isotope its unique atomic mass.
Chemical reactions involve electrons - not protons or neutrons. All isotopes of the same element have an identical number of electrons (just the number of neutrons differs) and hence the chemical properties are identical/very similar.
An atom of the same element that differs in the number of neutrons is known as an isotope. Isotopes have the same number of protons and electrons, which means they belong to the same element and have similar chemical properties. However, their differing neutron counts result in different atomic masses and can lead to variations in stability, with some isotopes being radioactive. For example, carbon-12 and carbon-14 are both isotopes of carbon, with different numbers of neutrons.
