How does the nucleus of an atom change after a gamma radiation? The atomic mass reduces by four and the atomic number reduces by two
The atomic mass remains the same, but the atomic number increases by one.
The atomic mass changes by one, but the atomic number remains the same,
Od
The atomic mass remains the same, but energy is lost as the nucleus decays.

Why doesn't heat added to water make the tempature rise above 100c

Me i dont know what to do! the table compares the number of electrons in two unknown neutral atoms. comparison of electrons atom number of electrons a 10 d 11 use this information to determine the number of valence electrons in the atoms. which of the following correctly compares the stability of the two atoms? both are unreactive. both are highly reactive. a is unreactive and d is reactive. a is reactive and d is unreactive.

Consider this initial-rate data at a certain temperature for the reaction described by
