প্রদত্ত মৌল সমুহঃ

Na(11), ভরসংখ্যা -23

P(15),ভরসংখ্যা -31

K(19), ভরসংখ্যা -40

Cu(29),ভরসংখ্যা 63

ধাপ-১। নিউট্রন সংখ্যা নির্ণয়ঃ

আমরা জানি, মৌলের প্রােটন সংখ্যাকে পারমানবিক সংখ্যা বলে, আর প্রােটন ও নিউট্রন সংখ্যার যােগফলকে ভরসংখ্যা বলে।

প্রদত্ত মৌলগুলাের নিউট্রন সংখ্যা বের করতে হলে এদের ভর সংখ্যা থেকে প্রােটন সংখ্যা বিয়ােগ করতে হবে।

এখানে, (i) Na-এর প্রােটন সংখ্যা 11

এবং ভর সংখ্যা 23

সুতরাং এর নিউট্রন সংখ্যা হবে (23-11)=12

(ii) Pএর প্রােটন সংখ্যা 15

এবং ভর সংখ্যা 31

সুতরাং এর নিউট্রন সংখ্যা হবে (B1-15)=16

(iii) Kএর প্রােটন সংখ্যা 19

এবং ভর সংখ্যা 40

সুতরাং এর নিউট্রন

সংখ্যা হবে (40-19)=21

(iv) Cu-এর প্রােটন সংখ্যা 29 

এবং ভর সংখ্যা 6

সুতরাং এর নিউট্রন সংখ্যা হবে (63-29)=34
