Suburban communities are usually located near to some major urban areas. While an urban area is congested with high population density, sub urban areas are less congested and have low or medium density. An urban area has good connection with surrounding amenities while a sub urban area has no such amenities and is located at some distance from the main city
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 daughternucleus 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>
