Answer:
pH scale
Explanation:
pH scale -
In the field of chemistry , the accurate and exact value of acidity or basicity in a particular solution is calculated with the help of a pH scale .
The scale has reading ranging from 1 to 14 ,
where ,
- If the pH value less than 7 indicates the solution to be acidic in nature ,
- If the pH value is exactly equal to 7 , the solution is neutral in nature ,
and ,
- If the pH value more than 7 indicates the solution to be basic in nature ,
Hence , from the given statement of the question ,
The correct answer is pH scale .

Because its in group one....which only lose or gain electrons.....thus it will only have oneelectron to fulfill its octect rule
Fission reactions generate thermal energy
The temperature,internal energy,and kinetic energy will all increase
