No. In both the cases the element would definitely change. As alpha particle comes out then the new element would have two less in atomic number where as in beta particle decay the new element will have one higher in atomic number.
One element decaying into another, which decays into another
In alpha decay, the atomic number decreases by 2, while the atomic mass number decreases by 4.
Americium decays into neptunium-239 through alpha decay. It has a half-life of 7,370 years.
daughter element
Parent and daughter in chemistry refer to radioactive decay, where a radioactive isotope of an element decays into another. For example, carbon-14 will beta-decay into nitrogen-14. The half-life associated with that particular process is about 5,700 years. The "parent" is carbon-14 and the "daughter" is nitrogen-14.
These terms apply to the decay of radionuclides. The parent isotope is 'the starting point' of a decay series that when it decays, by giving off radiation, changes into another element, or isotope of the original element (the daughter isotope). For example: When Uranium 238 (parent isotope) decays and gives off an alpha particle, it transmutes into Thorium 234 (the daughter isotope).

The atom that results from nuclear decay is called the daughter atom. The element of the daughter atom would be called the daughter element. The atom that decayed is called the parent.
true
Radio active parent elements decay to stable daughter elements i.e. the radio active parent Potassium 40 decays to Argon 40 Each radioactive isotope has it's own half life A half life is the time it takes for the parent radioactive element to decay to a daughter product, Potassium 40 decays to Argon 40 with a half life of 1 1/4 billion years. Therin lies the problem of storing nuclear waste

One element decaying into another, which decays into another
Negative beta (electron) decay; in which the mass number remains constant) and the atomic number of daughter atom in higher than the parent atom by one.
Uranium-239 decays by beta- decay to neptunium-239.
