The correct answer is:
18 and 8
According to the law of conservation of charge, we get
$7+2=1+Z \Rightarrow Z=8$
According to the law of conservation of mass, we get
$15+4=1+A \Rightarrow A=18$
Hence, the resulting atom has mass number 18 and atomic number 8 .
$7+2=1+Z \Rightarrow Z=8$
According to the law of conservation of mass, we get
$15+4=1+A \Rightarrow A=18$
Hence, the resulting atom has mass number 18 and atomic number 8 .
