A decay by `alpha` - emission is often followed by a `beta` decay. Why is it usually `beta^(-)` decay

Explain beta - decay ?

The nucleus ._(10)^(23)Ne decays by beta - emission. Write down the beta - decay. Write down the beta - decay equation and determine the maximum kinetic energy of the electrons emitted. Given that : m(._(10)^(23)Ne)=22.994466 u m(._(11)^(23)Na)=22.089770 u .

The hall lives of a radioactive sample are 30 years and 60 years from alpha- emission and beta- emission respectively. If the sample decays both by alpha- emission and beta- emission emission simultaneously, the time after which only one-fourth of the sample remain is

What value of pH in the mouth leads to tooth decay ? Why ?

What value of pH in the mouth leads to tooth decay ? Why ?

A radioactive element decays by beta- emission. A detector records " beta particles in 2 second it records (0.75 n beta particles (Given In2 = 0.6931, In3 = 1.0986). The mean life correct to nearest whole number is........... Second
