use the periodic table to write balanced equations for the decay of the following isotopes and beta decay. the alpha decay of 226/88 Ra : 226/88 Ra ⇒ + the beta decay of 218/84 Po: 218/84 Po⇒ +

Starting with only the balmer series light (visible light), how could we ensure that the solar panels generate a current that mark can use for his power station? a)by gradually increasing the brightness (amount) of light that we shine on it. b)by gradually increasing the frequency of the light we shine on it. c)by gradually increasing the wavelength of the light that we shine on it.
