total number of electrons =36
therefore the atomic number is 36 which is krypton
number of neutrons=45
therefore mass of the ion will be number of electrons+number of neutrons
=36+45
= 81
therefore the atomic number is 36 which is krypton
number of neutrons=45
therefore mass of the ion will be number of electrons+number of neutrons
=36+45
= 81

yes i do
but i get the answer
so whats the correct answer
correct answer is :- atumic number=35 and nass number = 80
the answer which u gave is wrong...
really how can the mass number of ion be 80 when the number of electrons are 36 and number of neutrons are 45
because mass no. does not depend upon no. of electrons
do u know what does a negative sign means???
woooooo
mass no. = no. of protons + no. of electrons

atomic number = 35 = Br(it has 45 neutrons )
mass number = no of protons + no. of neutrons
=35 + 45 = 80
this is Br- ion as it has 35+1 electrons and 45 neutrons
remark this if you liked
