The beta decay of cesium-137 has a half-life of 30 years. Answers: 1 Show answers Another question on Chemistry. Chemistry, 21.06.2019 22:30. Will mark brainliest 26. which of these statements are true? (3 points) a. gases are compressible b. gases

Cesium-137 has an atomic number of 55, so is written as. 137 55 Cs. It is also a β -emitter, which means it undergoes β -decay by a neutron decaying into a proton, releasing an electron. Protons and neutrons have the same mass, so the mass number doesn't change. The atomic number increases by one, because one more proton is formed.

How many beta particles are emitted by a 14.0-g sample of cesium-137 in three minutes? A)6.1 × 10S1U1P113S1S1P0 B)6.2 × 10S1U1P122S1S1P0 C)8.4 × 10S1U1P11S1S1P0S1U1P15S1S1P0 D)1.3 × 10S1U1P1-8S1S1P0 E)8.1 × 10S1U1P11S1S1P0S1U1P15S1S1P0 Cesium-138. 15758-29-9. Cesium, isotope of mass 138.

(3 points) a. gases are compressible b. gases Caesium-134 undergoes beta decay (β −), producing 134 Ba directly and emitting on average 2.23 gamma ray photons (mean energy 0.698 MeV). Caesium-135 Caesium-135 is a mildly radioactive isotope of caesium with a half-life of 2.3 million years. It decays via emission of a low-energy beta particle into the stable isotope barium-135.

It decays by emission of a beta particle and gamma rays to barium-137m. Since Cesium-137 is one of the most common radioisotopes used in industry, it would

About 94.6% decays by beta emission to a metastable nuclear isomer of barium: barium-137m (137m Ba, Ba-137m). The remainder directly populates the ground state of barium-137, which is stable. Cesium-137 decays in the environment by emitting beta particles.

Betastrålning vanliga radioaktiva ämnen ( Radon, Polonium, Radium, Plutonium och Cesium ). Cesium-137 decays in the environment by emitting beta particles. As noted above, cesium-137 decays to a short lived decay product, barium-137m.
