dear ruchendran 
electropossitive metals are those metals which have extra electrons and they tend to loose electrons and form possitive ions which is stable . 
so, they will emit electrons for sure , but pressure will not be the criteria for that , 
u need to put the light with required intensity and minimum threshold frequency .
