The atomic mass of aluminium is 27 and its atomic number is 13, the number of neutrons present in aluminium is _______?
ایلومینیم کا جوہری ماس 27 ہے اور اس کی جوہری تعداد 13 ہے ، ایلومینیم میں موجود نیوٹران کی تعداد _______ ہے؟
Answer: 14
Explanation
Number of neutrons = Atomic mass - Atomic number
= 27 - 13 = 14
Atomic number (13) gives the number of protons, and subtracting it from the atomic mass gives the neutrons.
