The product of the nuclear reaction in which 31p is subjected to neutron capture followed by alpha emission is ________.
2 answers:
Explanation:
A nuclear reaction is defined as a reaction in which two nuclei combine together to result in the formation of a new nuclei.
When two nuclei combine together then it is known as nuclear fusion. And, when a large nuclei split into two small nuclei then it is known as a nuclear fission reaction.
For example,
As we know that alpha particle is .
So, when is subjected to neutron capture followed by alpha emission then products are
along with emission of a positron.

Answer: One formula unit of NaCl consists of one cation, whose chemical symbol is and one anion whose chemical symbol is
Explanation:
For formation of a neutral ionic compound, the charges on cation and anion must be balanced. The cation is formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.
The cation is formed by the metal sodium which forms and the anion is formed by non metal chlorine which forms
.
For a formula unit of sodium chloride, the charges have to be balanced , thus the valencies of ions are exchanged and the neutral compound result. Thus
and
combine to form neutral
The arrangement of molecules within the 3 phases of matter are shown in the picture.
For the solid, the molecules are packed closely together. They don't have much space to move, so they just practically vibrate. For the liquid, the molecules are relatively farther from each other. The liquid molecules can flow freely but not as much as the gases. In the gases, the molecules are very far from each other. They are very sensitive to slight changes of pressure, volume and temperature.
