how many neutrons and protons are there in the following nuclei ?
`._(6)^(13)C, _(8)^(16)O,_(12)^(24)Mg,_(26)^(56)Fe, _(38)^(88)Sr`

Explanation

For `""_(6)^(12)C, Z=6 and A=12`. Therefore,
Number of protons =Z=6
Number of neutrons =A-Z=12-6=6
For `""_(8)^(17)O` Z=8 and A=17. Therefore,
Number of protons =Z=8
Number of neutrons =A-Z=17-8=9
For `""_(12)^(25)Mg`, Z=12 and A=25. Therefore,
Number of protons =Z=12
Number of neutrons =A-Z=25-12=13
For `""_(26)^(56)Fe, ` Z=26 and A=56. Therefore,
Number of protons =26
Number of neutrons =A-Z=56-26=30
For `""_(38)^(56)Fe,` Z=26 and A=56. Therefore
Number of protons =38
Number of neutrons =A-Z=88-38=50
