How is the atomic number and mass number related to the number of neutrons and protons inside an atom
Answers
Hey mate here's your answer....
The Number of protons indicates the atomic number in the sense that the number of protons is equal to the Atomic number of a particular atom...
And Mass number of an atom is determined by the combined weight of the nucleus containing the mass of neutrons and protons....
Note:- The mass of electrons are taken as negligible as it has a comparatively very very less mass ..
Hope this helps.. This is of my own knowledge so plz mark as brainliest..
Answer:
The atomic number refers to the number of protons present in the nucleus of an atom of a specific element.
→ The atomic number [Z] refers to the no. of protons present in the atom.
Atomic mass refers to the sum of protons and neutrons present in an atom.
→ If we want to find the no. of neutrons in an atom, subtract the atomic number[Z] from the mass no. [M].
Conclusion
Atomic number refers to the no. of protons present in the nucleus of an atom and is denoted by the symbol Z. Mass number refers to the total sum of protons and neutrons in an atom and we can find the neutron number from the mass number.
Knowledge Bytes
→ The no. of protons and electrons in a neutral atom is equal.
→ We do not weigh the mass of electrons as they have negligible weight.
→ We write the mass number above the symbol of a specific element while the atomic number is written as a subscript (below the element symbol).
