Explanation:
In an atom , the relation between the subatomic particles of the atom are given as follows -
For a neutral atom ,
Atomic number = number of protons = number of electrons ,
Mass number = number of protons + number of neutrons,
Hence , from the given information of the question,
number of neutrons = 49 ,
number of electrons = 36 ,
Hence , by using the above relation,
Atomic number = 36
number of protons = 36
Since ,
Mass number = number of protons + number of neutrons
Mass number = 36 + 49 = 85 .
By taking the help of periodic table , as atomic number = 36 ,
The elements is Krypton ( Kr )
Kr ⁸⁵₃₆
