Electrons fall from higher energy state to lower energy state in atoms. This can be from outer shells to empty spaces in inner shells or from outside the atom to an empty space in a shell.

Does beta radiation results in the emission of electrons?
In beta radiation, an emission of electrons can occur due to beta decay. A neutron can disintegrate into protons and electrons.
What changes occur when a radioactive isotope disintegrates?
high-speed atomic particles occur
Does fusion reaction occur in an atomic bomb?
They have a starter in a bomb and what this will do is shoot a neutron in the nuclear fuel starting a chain reaction
What is the atomic mass of gadolinium?
The atomic mass of gadolinium is 157.25 (which is the measured mass based on the various isotopes which occur in nature).
Which atomic mass is the threshold value below which fusion may occur?
56
What happens inside an extinguisher when the handle is pressed?
Combustion occur and emission
What changes in atomic number and mass number occur in beta emission?
Electron (beta minus) decay: the atomic mass remain approx. constant, the atomic number will be greater with 1 Positron (beta plus) and electron capture decay: the atomic mass remain approx. constant, the atomic number decrease with 1 Double beta decay: the atomic mass remain approx. constant, the atomic number will be greater with 2
How many times emission occur in radioactive series?
around ten 10

What changes occur when a radioactive isotope disintegrates?
high-speed atomic particles occur
Why inert gases occur in atomic form?
to get stability
Does fusion reaction occur in an atomic bomb?
They have a starter in a bomb and what this will do is shoot a neutron in the nuclear fuel starting a chain reaction
When does atomic number occur?
It doesn't occur its just the way an way they measure atoms in an element
Which atomic number is the threshold value which fusion will occur?
56
Emission nebulae like M42 occur only near stars that emit large amounts of?
ultraviolet radiation
When does Thermionic emission occur during x-ray production?
thermionic emission occurs when the filaments are heated to a certain degree, causing the electrons to boil off and form a space charge or electron cloud.
Where and why do floods occur?
a flood can occur anywhere. It happens when there is a lot of
