Select the correct statement (s) :

Answer»

`alpha`- PARTICLES are simply dipositive helium nucleus
`gamma`-rays TRAVEL with higher speed as compare to `alpha`- particle and have higher ionization POWER as compared to `beta`- particle
A LOSS of `beta`- particle results in the production of isobars
`beta`- particles are considered to be the best bombarding particles

Solution :`alpha` - particle = `He^(+2)` ion , `gamma`- ray = no charge & no Mass its speed = velocity of light
