How many neutrons helium has?
Helium-4 has 2 protons and 2 neutrons. The less common helium-3 has 2 protons but only 1 neutron. There are also several additional isotopes (that is, different number of neutrons), but those are unstable (radioactive).
Is calcium unstable ans also radioactive?
Calcium is mostly stable
Is helium stable or unstable?
Helium is a stable element.
What is the difference between radioactive and non-radioactive isotope?
Radioactive minerals are unstable and emit radiation at a constant rate. They also have half lives and lose energy overtime. Nonradioactive minerals are stable, and by there own are incapable of emitting energy.
What are the unstable element?
Radioactive elements are unstable, and the shorter the half-life, the more unstable they are.
When an isotope is blank it is radioactive?
When an isotope is unstable, it is said to be radioactive.
Why some radioactive sources contains traces of helium gas?
Some radioactive sources contain traces of helium gas due to the process of alpha decay, where an unstable atomic nucleus emits alpha particles made up of two protons and two neutrons. When these alpha particles are released, they can capture electrons from their surroundings, forming helium atoms. Over time, as radioactive materials decay, the accumulation of helium can occur, which may be observed in certain geological or laboratory settings. This phenomenon is often used in studies of radioactive decay and the age of materials.
What is An unstable isotope is called what?
It isn't really an ELEMENT that is unstable, but an ISOTOPE. That means that in general, for the same element, some atoms will decay, and some will not - the difference being the number of neutrons in the nucleus.
Are helium balloons radioactive?
No, helium balloons are not radioactive. Helium is a non-toxic, inert gas often used to fill balloons because it is lightweight and does not react with other chemicals. It is safe for decorations and festivities.
True or false unstable atom that decomposes and emits energy is called retroactive?
No, it's called "radioactive." "Retroactive" is something that's active in regards to the past.
What are isotopes considered radioactive?
Not all isotopes are radioactive; the radioactive isotopes are unstable and emit radiations.
Can nuclear energy be part of the solution to your energy crisis and climate change?
Most certainly, nuclear energy can be part of the solution to our energy needs. What the world wants to get away from is nuclear power that relies on fission, or breaking apart the atoms, of radioactive/unstable elements such as uranium. Helium-3 is an isotope of helium that is not radioactive/unstable. Researchers at the University of Wisconsin, Fusion Technology institute have succeeded in fusing helium-3 atoms, demonstrating that nuclear power, with no radiation whatsoever is not only possible, but it is ready to be fully developed and used.
