Em tham khảo nha:
\(\begin{array}{l}
d)\\
2{p_Z} + {n_Z} = 46\\
2{p_Z} = 1,875{n_Z}\\
\Rightarrow {p_Z} = 15;{n_Z} = 16\\
A = 15 + 16 = 31\\
\Rightarrow {}_{15}^{31}Z\\
e)\\
2{p_A} + {n_A} = 58\\
{n_A} = 52,64\% \times 2{p_A}\\
\Rightarrow {p_A} = 19;{n_A} = 20\\
A = 20 + 19 = 39\\
\Rightarrow {}_{19}^{39}A\\
g)\\
2{p_E} + {n_E} = 40\\
{n_E} - {n_P} = 1\\
\Rightarrow {n_E} = 14;{p_E} = 13\\
A = 13 + 14 = 27\\
\Rightarrow {}_{13}^{27}E
\end{array}\)
