The highest penetrating radioactive material is the _______________. It is not really a particle, but a wave with no _______________ and no _______________.

When an electron is thrown out of the nucleus, it is known as a _______________ decay.

Determine if the nuclear equation $$^{214}_{84}\text{Po} \rightarrow \text{ }^{210}_{82}\text{Pb} + \text{ }^{4}_{2}\text{He}$$ represents Alpha Decay ($\alpha$), Beta Decay ($\beta$), and/or gamma rays ($\gamma$).

Which type of decay is represented by the nuclear equation $$^{14}_{6}\text{C} \rightarrow \text{ }^{14}_{7}\text{N} + \text{ }^{0}_{-1}\text{e}$$ ?

Identify the type of decay in the nuclear equation $$^{222}_{86}\text{Rn} \rightarrow \text{ }^{218}_{84}\text{Po} + \text{ }^{4}_{2}\text{He} + \text{ }^{0}_{0}\text{y}$$ .

What type of decay is shown in the nuclear equation $$^{18}_{9}\text{O} \rightarrow \text{ }^{18}_{8}\text{F} + \text{ }^{0}_{-1}\text{e}$$ ?

Complete the nuclear equation $$^{254}_{91}\text{Pa} \rightarrow \text{ }^{0}_{-1}\text{e} +$$ and determine the type of decay.
