What is the nuclear equation for radium 226

Note that the sum of the subscripts atomic numbers or charges is the same on each side of the equation. Now try figuring out Am Check your answer by watching the video below!

All nuclei with an atomic number Z greater than 82, are considered unstable. Alpha decay occurs in the nuclei of heavy elements, like radium, uranium, thorium, etc. When a nucleus of Ra radium decays, it emits an alpha particle and becomes an Rn radon nucleus.

In general, during alpha decay, the atomic number Z is reduced by two, and the mass number A , by four. For example, alpha decay generates Rn with atomic number 86 and the mass number from Ra with the atomic number 88 and the mass number Alpha particles are very heavy and contain high amounts of energy MeV. They usually pass short distances a 5 MeV alpha particle will travel about 20 micrometers in silicon and can be stopped by a sheet of paper.

Alpha particles do not produce Bremsstrahlung radiation when slowing down. Alpha particles are not generally dangerous unless the source is ingested or inhaled since alpha radiation is the most destructive form of ionizing radiation.

Historically, radium and radon were the principal alpha emitters of medical interest. Radium dichloride is still used today in treating osseous metastases. Other alpha emitters are being researched for therapeutic approaches using radiopharmaceuticals that can target the delivery of short half-life alpha emitters into cancerous cells. Due to their very short range, alpha particles have the potential to deliver a lethal radiation dose to small metastatic cell clusters, while mostly sparing the surrounding tissue.

All work with alpha emitters must be conducted under very strictly controlled conditions. Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys.

It occurs in the atomic level; in fact, in the nucleus of an atom. Essentially, radioactive decay happens when an unstable atom wants to lose energy and become stable again.

It does that by emitting something out of its nucleus , which transforms into a different nucleus or into a nucleus in a different state. There are many different types of radioactive decay. One of the most common types is alpha decay : the nucleus emits an alpha particle , which is simply a helium nucleus with no electrons, and transforms into a nucleus with atomic number reduced by two units and mass number reduced by four units.

So when you add up the A's and Z's on both sides of the equation, you get the same values. Now, we've got a radium atom. That means that its mass number is equal to ; elements occur, in nature or in lab, in many different forms, with of course the same atomic number but varying amounts of neutrons, resulting in varying mass numbers. These different 'versions' of an element are known as isotopes. Radium is a highly radioactive element in all forms, and radium is its most stable or, at least, longest-lived isotope.

So this radium atom wants to lose energy.
