Q. Are two atoms of the same element identical? 
A. Yes, two atoms of the same element are identical. But sometimes it may be different these may be reffered as isotopes. 


Q.what are isotops?  
A.  Isotops are  chemical substance   having same proton number but different in mass number.

Q.   What is buffer solution?
A.  The solution which prevent chaning of pH value after adding a small amount of acid / base in it.

Q.what is MSDS? 
A. MSDS or material safety data sheets is a safety sheet that is used for preventing the accidents may be occured  because of the ignorance of usage of any chemical substance. 

Q. Can water be liquid below 0°c?  
A. No, the freeing point of water is 0 degree so water can not be liquid below this temperature. 

Q.  what is Hammond acidity function?    
A. Sometimes pH scale is unable to measure the acidity of an acid for this reason hammond account a function which is able to measure acidity of acids like 18 M H2SO4.

Q.why chemistry is so important in our daily life?  
A. Chemistry is one of the fundamental  in the world and a branch  of science  that is a complete bridge of life and Matter,  if we want to know about   our live and environment its a great study then. From the morning to night every things that we use directly or indirectly related to chemistry. 


Q. What are radioactive substance? 
A. The substance causes radioactivity, substances emits radioactive ray mostly  alpha beta gamma and other rays.


Q. What are best chemistry journals? 

A. The best chemistry journals are 

1.   Chemistry Review.
2. Chemcomm. 
3. Nature chemistry. 
4. Chemistry of  material.
5. Account of chemical research.  
6.Angewandte chemie.
7. Chemical society reviews.  Etc.

Q. What is the impact factor of a journal? 
A. The impact factor of a journal is considered as the number of citations that published by the given journal it receives. It is also considered that  a journal have higher impact factor is more important journal than any other journal have low impact factor (IF).
