A) 35 and 45
B) 45 and 35
C) 40 and 40
D) 30 and 50
Correct Answer: A
Solution :
\[_{35}B{{r}^{80}}\,=\,\,1{{s}^{2}}\,2{{s}^{2}}\,2{{p}^{6}}3{{s}^{2}}3{{p}^{6}}3{{d}^{10}}4{{s}^{2}}4{{p}^{5}}\] \[A=\,80\], \[Z=\,35\], \[N=\,?\] \[N=A-Z=80-35=45\] atomic number (Proton) is 35 and no. of neutron is 45.You need to login to perform this action.
