A family of people often consists of related but not identical individuals. Elements have families as well, known as isotopes. Isotopes are members of a family of an element that all have the same number of protons but different numbers of neutrons. Ssh shell client.
Isotopes of an element have same the atomic number but different mass numbers. Now, atomic number of an element = number of protons = number of electrons Therefore, the electronic configuration is the same for isotopes and as the chemical properties depend upon the electronic configuration, latter is also the same. Jan 25, 2016 All atoms of an element have the same atomic number. All isotopes of the same element, such as hydrogen, have the same number of protons (same atomic number) but different numbers of neutrons in their nuclei. There are three isotopes of hydrogen; hydrogen-1, hydrogen-2, and hydrogen-3. The atomic number of hydrogen is 1. 6) Isotopes of the same element have the same number of PROTONS but different number of NEUTRONS. 7) Statement A is CORRECT since a neutral atom consists of equal number of electrons and protons (equa view the full answer Previous question Next question.
The number of protons in a nucleus determines the element's atomic number on the Periodic Table. For example, carbon has six protons and is atomic number 6. Carbon occurs naturally in three isotopes: carbon 12, which has 6 neutrons (plus 6 protons equals 12), carbon 13, which has 7 neutrons, and carbon 14, which has 8 neutrons. Every element has its own number of isotopes.
Isotopes Of An Element Have The Same Number Of Protons
The addition of even one neutron can dramatically change an isotope's properties. Carbon-12 is stable, meaning it never undergoes radioactive decay. Carbon-14 is unstable and undergoes radioactive decay with a half-life of about 5,730 years (meaning that half of the material will be gone after 5,730 years). This decay means the amount of carbon-14 in an object serves as a clock, showing the object's age in a process called 'carbon dating.'
Isotopes have unique properties, and these properties make them useful in diagnostics and treatment applications. They are important in nuclear medicine, oil and gas exploration, basic research, and national security.

DOE Office of Science & Isotopes
Isotopes are needed for research, commerce, medical diagnostics and treatment, and national security. However, isotopes are not always available in sufficient quantities or at reasonable prices. The DOE Isotope Program addresses this need. The program produces and distributes radioactive and stable isotopes that are in short supply, including byproducts, surplus materials, and related isotope services. The program also maintains the infrastructure required to produce and supply priority isotope products and related services. Finally, it conducts research and development on new and improved isotope production and processing techniques.
Isotope Facts
- All elements have isotopes.
- There are two main types of isotopes: stable and unstable (radioactive).
- There are 254 known stable isotopes.
- All artificial (lab-made) isotopes are unstable and therefore radioactive; scientists call them radioisotopes.
- Some elements can only exist in an unstable form (for example, uranium).
- Hydrogen is the only element whose isotopes have unique names: deuterium for hydrogen with one neutron and tritium for hydrogen with two neutrons.

Scientific terms can be confusing. DOE Explains offers straightforward explanations of key words and concepts in fundamental science. It also describes how these concepts apply to the work that the Department of Energy's Office of Science conducts as it helps the United States excel in research across the scientific spectrum.
