Answer:

Yes, the first person is correct. The atomic number will still be 92, and the mass number will still be 235.

Step-by-step explanation:

Alpha Decay: The mass number decreases by 4, and the atomic number decreases by 2.

Beta Decay: The mass number has no change, and the atomic number increases by 1.

Positron Emission: The mass number has no change, and the atomic number decreases by 1.

Gamma Decay: The mass number has no change, and the atomic number has no change.

ATOMIC NUMBER: The total number of protons.

MASS NUMBER: The total number of protons and neutrons.

Answer:the mass number and atomic number would be the same as the original uranium

Explanation:The are three main types of radiation that is emitted from a radioactive substance. They include alpha, beta and gamma rays.

In the alpha emmision, the nucleus of the original atom results in a daugther atom with an atomic number 2 less and a mass number 4 less.

In a beta emmision, the nucleus of the original atom emits either a negatron or a positron. In a negatron, the atomic number increases by 1 and the mass number is unchanged, while in a positron, the atomic number decreases by one and the mass number is unchanged.

In a gamma emmision, the gamma rays are electronegative waves . It is usually goes with an alpha and beta emmision. Therez is no change in the atomic or mass number of the original atom. It involves the transition of a nucleon from one energy state to another.
