Answer : The missing part is,
Explanation :
Nuclear fission : It is a process in which a heavy nuclei absorbs a neutron, they split or fission into two small nuclei and 3 neutrons.
Atomic number of Cf = 98
Atomic mass of Cf = 252
Atomic number of Te = 52
Atomic mass of Cf = 136
Atomic number of unknown element = [(252 + 1) - (136 + 3)] = 114
Atomic mass of unknown element = 98 - 52 = 46
So, the unknown element is, palladium (Pd)
The complete nuclear fission of a californium atom will be,
Hence, the missing part is,
The ozone layer absorbs radiation from the sun, helping to increase the temperature in the upper portion of the stratoshpere
Electron gain enthalpy of the atom - if im not wrong
The changes in matter/energy can be classified as follows:
- Physical changes - Crystallizing salt from seawater
- Chemical changes - ripening fruit
- Nuclear changes - production of elements in the stars
<h3>What are physical, chemical and nuclear changes?</h3>
Matter and energy undergo physical, chemical and nuclear changes.
Physical changes are changes in which no new product is formed.
Chemical changes are changes in which no new product is formed.
Nuclear changes are changes in which no new product is formed.
Examples of each of the given changes is as follows:
- Physical changes - Crystallizing salt from seawater
- Chemical changes - ripening fruit
- Nuclear changes - production of elements in the stars
Therefore, matter/energy undergo changes.
