Even though plutonium-239 (t₁/₂=2.41310⁴ yr) is one of the main fission fuels, it is still a radiation hazard present in spent u
zalisa [80]

Radioactive isotopes eventually decay, or disintegrate, to harmless materials. Some isotopes decay in hours or even minutes, but others decay very slowly. Strontium-90 and cesium-137 have half-lives of about 30 years (half the radioactivity will decay in 30 years). <u>Plutonium-239 has a half-life of 24,000 years.</u>

<h3>What is radioactive decay? </h3>

Radioactive decay is the emission of energy in the form of ionizing radiation. The ionizing radiation that is emitted can include alpha particles, beta particles and/or gamma rays. Radioactive decay occurs in unbalanced atoms called radionuclides.

Elements in the periodic table can take on several forms. Some of these forms are stable; other forms are unstable. Typically, the most stable form of an element is the most common in nature. However, all elements have an unstable form. Unstable forms emit ionizing radiation and are radioactive. There are some elements with no stable form that are always radioactive, such as uranium. Elements that emit ionizing radiation are called radionuclides.

Cesium sulfite is formed from the cs cation and the so2−3 anion. What is the correct formula for this compound?
Anna35 [415]

Cesium Sulfite is formed from the Cs cation and the SO₃⁻² anion. The correct formula for this compound is Cs₂SO₃.

<h3>What is Cation ? </h3>

Cations are positively charged ions. It forms when an element lose one or more electrons.

<h3>
What is Anion ? </h3>

Anions are negatively charged ions. It form when an element gains one or more electrons.

Symbol         Cs⁺¹         SO₃⁻²

Valency           +1              -2

Formula of the compound is Cs₂SO₃.

Thus from the above conclusion we can say that Cesium Sulfite is formed from the Cs cation and the SO₃⁻² anion. The correct formula for this compound is Cs₂SO₃.
