The nuclei of all plutonium isotopes contain the same number of protons.
Number of protons in the nuclei of their atoms.
Different elements with same number of neutrons are known as isotones.
No! Nuclides with different element names are never isotopes of each other, because their nuclei contain different numbers of protons and therefore are not chemically alike.
All isotopes of an element have the same number of protons in the atomic nucleus, which is its atomic number on the periodic table. All isotopes of an element contain different numbers of neutrons in their atomic nuclei, which causes the isotopes of an element to vary in mass number (protons + neutrons).
The two notations represent atoms that are isotopes of the same element is 121 Sn and 119 Sn. The atomic mass of an element is defined as the weighted average mass of that elements naturally occurring isotopes.
All have the same number of protons and electrons. They differ in the number of neutrons.
Neutrons
YES!
Isotopes of an element have different masses because their nuclei have different numbers of neutrons.
Different numbers of neutrons in their nuclei.
Isotopes are atoms of the same element with different numbers of neutrons. Stable isotopes have a balanced number of protons and neutrons, meaning their nuclei do not decay over time. Unstable isotopes, also known as radioactive isotopes, have an imbalance of protons and neutrons, causing their nuclei to decay and emit radiation over time.
Number of protons in the nuclei of their atoms.
Helium is produced
Isotopes are atoms of an element having different number of electrons.
Isotopes of an element have nuclei with the same number of protons (the same atomic number) but different numbers of neutrons Neutrons (:
Atoms of all isotopes of a single element have the same number of protons in their nuclei but have different numbers of neutrons if they have different mass numbers.
Different elements with same number of neutrons are known as isotones.
