Identify whether each reaction represents a chemical reaction or a nuclear reaction by filling in the blank with the word ‘chemi
2 answers:
Answer 1) 
+ 
----> 2 HCl
This is a pure chemical reaction that is taking place.
In this reaction the two chemical species which are Chlorine and Hydrogen undergo addition reaction and form two moles of hydrochloric acid. No new species is formed except the combination of reactants which gives the product.
Answer 2) H + H ----> He + n
This is a nuclear reaction.
As the reactant species is undergoing a reaction which is resulting in formation of new species completely different than the elements in reactants.
Also there is a neutron which is generated after the reaction this is clear indication of nuclear fusion reaction. Hence, it can be called as nuclear reaction.

Answer: The electronic configuration of Chlorine will be
Explanation: Chlorine is an element which belongs to the P-block of the periodic table. Its atomic number is 17.
Atomic Number = Number of electrons
Number of electrons = 17
The nearest noble gas which lies to Chlorine is Neon which has 10 electrons. Rest of the 7 electrons are filled in the 3s and 3p orbitals. Hence, the electronic configuration of Chlorine is
