- अणु संख्या: केंद्रकामध्ये उपस्थित असलेल्या प्रोटॉनची संख्या म्हणून त्याची व्याख्या केली जाते. हे Z अक्षराने दर्शविले जाते.
- वस्तुमान संख्या:केंद्रकामध्ये असलेल्या प्रोटॉन आणि न्यूट्रॉनच्या एकूण संख्येला घटकांची वस्तुमान संख्या म्हणतात. हे अक्षर A द्वारे दर्शविले जाते.
- तटस्थ अणूसाठी,
- अणूमध्ये प्रोटॉनची संख्या = Z
- अणूमधील इलेक्ट्रॉन्सची संख्या = Z
- अणूमधील न्यूक्लिओन्सची संख्या = A
- अणूमध्ये न्यूट्रॉनची संख्या = N = A – Z
गणना:
- वरून हे स्पष्ट होते की न्यूट्रॉनची संख्या वस्तुमान संख्या आणि अणु संख्या यांच्यातील फरकाच्या समान आहे.
