What is the daughter nucleus (nuclide) produced when 211 Pb undergoes beta decay by emitting an electron? Replace each question

poizon [28]

<h2>Daughter Nucleus</h2>

Explanation:

The original nucleus is known as the <em>parent nucleus</em>, and the core staying after the rot is known as the daughter nucleus
If a core radiates an alpha molecule, it loses two protons and daughter nucleus in this way, the little girl core has a nuclear mass of 4 less and a nuclear number of 2 not exactly the parent core
In β-decay, a neutron is changed over into a<em> proton, electron, and electron-anti neutrino</em>
Which builds the nuclear number of the nuclide by 1. <em>For 211Pb, this would bring about a nuclide of 211Bi.</em>
