Isotopes
Isotopes are atoms that have different number of neutrons, so they have a different mass number than the other atoms in an element.

What is the nuclear decay for francium?
Francium-223 decay to radium-223; each isotope have another type of decay.
How are isotopes the same but different?
Isotopes are different forms of the same element which have different numbers of neutrons in their atomic nuclei. A given element is identified by the number of protons in its nucleus; that's its atomic number. Two different isotopes of the same element have the same number of protons, but each has a different number of neutrons in its nucleus. Different isotopes of the same element are chemically the same.
an element is stable when it has a full outer shell of electrons. to abide by the octet rule it must have a shell of 2 then 8 electrons. An element with a full outer shell (8) will be stable and act like its nearest noble gas.
The number of the velence electrons is frequently the same.
What is the nuclear symbol and hyphen notation for 26 protons and 30 neutrons?
These symbols are:
5626U and Fe-56.
Isotopes are the same as ions?
Isotopes are atoms of an element having different number of neutrons.
Ions are atoms with an electrical charge.
When curium-242 is bombarded with alpha particles a neutron and are formed?
The nuclear reaction is: 242Cm + 4He = 245Cf + n
How old is a piece of wood that has 0.7813 percent of the carbon-14 of a living organism?
40110 years
What happens to the radioactive isotopes that are released in a nuclear reaction?
they decay over time
How do isotopes of An differ from one another?
They differ from each other in the number of neutrons, and therefore also the mass. They will also have different stabilities (for example, some of them may be radioactive), but this is complicated.
Can an isotope have less number of neutrons?
absolutely. such isotopes are likely to decay by emitting positrons or by K capture, instead of by emitting electrons when they undergo beta type decay.
What do you know about an isotope?
Isotopes have same atomic number. They have different mass numbers. Their physical properties are different.
What is the same about isotopes and atom?
All the isotopes of an atom have the same number of protons but different number of neutrons.
During radioactive decays heat is released.
What is isotopes name the isotopes of hydrogen and draw the structure of their atoms?
Isotopes of hydrogen are Hydrogen-1 (protium), Hydrogen-2 (deuterium), and Hydrogen-3 (tritium).
What are nitrogens stable isotopes?
Nitrogen has three stable isotopes. Namely they are nitrogen-14, nitrogen-15 and nitrogen-16.
What is the most common isotope in hafnium?
Hafnium-174 is the most common isotope of hafnium, making up about 31% of naturally occurring hafnium.
What fraction of the radioisotope remains in the body after one day?
If an isotope is absorbed into the body, the fraction that remains after one day depends on the radiological half-life of the isotope and the biological half-life (basically how fast the element can be eliminated from the body) of the element that the isotope represents.
If carbon has an atomic number of 6 is it stable?
Isotopes carbon-12 and carbon-13 are stable; the isotope carbon-14 is radioactive and unstable.
The atomic number is the same for all isotopes.
