(A) During `beta`-decay, a new element with atomic number greater than one is obtained.
(R ) Protons and neutrons keep on changing into one another through meson.

A neutral atom, with atomic number greater than one consists of

During beta decay of a nucleus, how does the neutrons to proton ration change?

In which one of the following , the number of protons is greater than neutrons but number of protons is less than the number of electrons

Is it possible for the atom of an element to have one electron, one proton and no neutron. If so, name the element.

Is it possible for the atom of an element to have one electron, one proton and no neutron. If so, name the element.

In both beta^(-1) and beta^(+) decay processes, the mass number of a nucleus remains same, whereas the atomic number Z increases by one in beta^(-) decay and decreases by one in beta^(+) decay. Explain by giving reason.
