Answer:-
Alpha decay
Explanation:-
Uranium 238 has atomic number 92 and mass number 238.
Thorium 234 has atomic number 90 and mass number 234.
So, the change in atomic number as uranium 238 disintegrates into thorium234 = 92 – 90 = 2
So, the change in mass number as uranium 238 disintegrates into thorium234= 238 – 234 = 4
We know that when an alpha particle is emitted, the mass number decreases by 4 and the atomic number decreases by 2.
So when an atom of uranium 238 undergoes radioactive decay to form an atom of thorium-234, alpha decay has occurred.
Answer:
Water and Salt
Explanation:
A neutralization reaction occurs when an acid and a base react to produce water and a salt, and it entails the formation of water from the mixture of H+ and OH- ions.
The charge of a nucleus is positive
That would be an amino acid. The
and -COOH is the functional group for a carboxylic acid hence AMINO ACID.
