Question

An atom of element contains 29 electrons and 35 neutrons write number of proton and its electronic configuration

Answer 1

here is your answer

as the atom contain 29 electron it should also contain 29 proton and hence its atomic number is 29

the element with atomic number 29 is copper Cu

it electronic configuration  is a bit complex it can be 2,8,17,2

                                                                                  or  2,8,18,1

this happens because the second electronic configuration the third shell becomes full so it becomes more stable to gain this stablity the Cu atom pushes one of its electron in the last shell to the before shell

hope this helps

mark me as brainliest

   

Answer 2

the atom is copper  this is answer
