in beta decay,atomic number increases by one unit,mass number decreases by one unit,what happens to electron number in the atomc orbitals?( as the electron formed is emitted)
When the temperature of pure Cu is reduced from 300 Kelvin to 4 Kelvin, its resistivity decreases by a factor much larger than the brass (Cu + Zn) when cooled in the same way. Why?
A blood corpuscle has a diameter about 9x10-6 in which excited orbit should a hydrogen atom should be so that it is just about as big as the blood corpuscle?
Tungsten (W), with a mass number of 185 and an atomic number of 74, decays by beta emission. Identify the product of the nuclear reaction by providing its atomic symbol (5 pts), mass number (5 pts), and atomic number (5 pts)
Hello.I want to ask is it possible for a stone to have some magnetic power different from power that we see in ordinary metal magnets.something like earth gravity that attract everything.Some one told me that he saw a stone that attract other smaller stone but did not attract metals.
Is it practical possible in science?
