Number of neutrons in the nucleus.
difference is number of neutrons.
Different numbers of neutrons, e.g. deuterium and tritium are isotopes of hydrogen.
Every atom of the same element is also categorized by its number of neutrons. An atom with a certain number of neutrons is an "isotope." Two atoms of the same element (same quantity of protons) can be different isotopes (different quantity of neutrons). Some isotopes are unstable, so most stable isotopes of an element are withing a range of a few numbers. For example, stable isotopes of carbon are Carbon-12 and Carbon-13.

Dalton's Atomic Theory 1) All matter is made of atoms. Atoms are indivisible and indestructible. 2) All atoms of a given element are identical in mass and properties 3) Compounds are formed by a combination of two or more different kinds of atoms. 4) A chemical reaction is a rearrangement of atoms.
Isotopes and Electrons
Iron is the major element in steel. Only an element can be an element, and an element can not be a compound, the definition of which requires more than one element.
Yes, this is the definition of an isotope. By definition, an element is determined by the number of protons in the nucleus - changing the number of protons changes the element. Electrons are involved with bonding, but don't affect atomic mass (very much, for most current practical purposes). Neutrons don't affect what element you have but have a major impact on atomic mass as well as radioactivity.
There's no difference on this statistical subject among developed, underdeveloped and emerging countries.
In among the hidden, what are the major plot events in order?
yes it is
