Question

What new element is formed during the beta decay of Tc-99? * 1 point

U-238
Helium
O An electron
Ruthenium

Answer 1

An electron (beta particle)

Step-by-step explanation:

During the beta decay of Tc-99 (Technetium-99), an electron (beta particle) is formed. This process involves the transformation of a neutron into a proton within the nucleus of the atom, with the emission of an electron and an antineutrino. The resulting element after beta decay is Ruthenium-99.
