What else can I help you with?
What makes two istopes of the same element different?
istopes have different numbers of neutrons and most of their elements have several istopes
How are istopes identified?
by their mass numbers.

What are Atoms of the same substance that have different number of neutrons?
istopes
Are helium-4 and helium-3 istopes?
Yes, they are isotopes of helium
What subatomic particle varies in number in all the istopes of a particular element?
neutrons
What they hyphen notation of the common istopes for francium are?
Examples: francium-223 or Fr-223.
What is one type of atom such as hydrogen?
A type of an ATOM is known as an ISOTOPE. Look up "HYDROGEN istopes" DEUTERIUM and TRITIUM on GOOGLE They both still have one proton, deutererium has one neutron as well. Tritium has one proton but 2 neutrons. Some isotopes are radioactive as they are trying to decay to a STEADY STATE of balance within the atomic structure.
How are istopes of the same element alike?
Same number of protons; identical or very similar chemical properties.
How do istopes hydrogen -2 and hydrogen -3 differ?
The hydrogen-2 isotope, sometimes called "deuterium", contains one proton and one neutron in the nucleus of the atom, instead of having only one proton. THis makes it heavier than normal, and is sometimes called "heavy hydrogen". The hydrogen-3 isotope, called "tritium", has one proton and TWO neutrons, and is somewhat radioactive. Tritium has a half-life of 12.3 years, and decays into helium-3.
