Radioactive Emissions and Their Effects

The video tutorial covers the basics of radioactivity, focusing on the laws governing alpha, beta, and gamma emissions. It explains how alpha particles affect atomic mass and proton numbers, leading to element changes, using uranium as an example. Beta emissions involve neutron-to-proton transformations, altering the element without changing mass. Gamma radiation, being an electromagnetic wave, does not affect atomic mass or proton numbers.

What are the three types of radioactive emissions discussed in the video?

• Alpha, Gamma, and Delta

• Beta, Gamma, and Delta

• Alpha, Beta, and Gamma

• Alpha, Beta, and Delta

What happens to the mass number of Uranium when it emits an alpha particle?

• It increases by 2

• It remains the same

• It decreases by 4

What is the new element formed when Uranium emits an alpha particle?

• Polonium

• Radium

• Protactinium

• Thorium

What is the mass and proton number of an alpha particle?

• Mass 2, Proton 2

• Mass 4, Proton 2

What happens to a neutron in the nucleus during beta emission?

• It splits into a proton and an electron

• It splits into two electrons

• It splits into two protons
