కాన్సెప్ట్:

  • ఎలక్ట్రాన్లు, ప్రోటాన్లు మరియు న్యూట్రాన్లు అణువు యొక్క మూడు ప్రధాన ప్రాథమిక కణాలు.

5fb7b645f67db6ccfb78c8ed 16406168144471

  • అణువు యొక్క కేంద్రకంలో, ప్రోటాన్లు మరియు న్యూట్రాన్లు ఉన్నాయి.
  • ఎలక్ట్రాన్లు అణువు యొక్క కేంద్రకం చుట్టూ తిరుగుతాయి.

ప్రోటాన్ల సంఖ్య = ఒక మూలకం యొక్క పరమాణు సంఖ్య.

న్యూక్లియై = న్యూట్రాన్ + ప్రోటాన్

వివరణ:

  • న్యూట్రాన్‌ను ఫిబ్రవరి 1932లో చాడ్విక్ కనుగొన్నాడు.
  • ఎలక్ట్రాన్‌ను 1897లో జె.జె.థామ్సన్ కనుగొన్నారు.
  • ప్రోటాన్‌ను ఎర్నెస్ట్ రూథర్‌ఫోర్డ్ 1920లో కనుగొన్నారు.
