Hello friends, last time we discussed the charge of a neutron. Today we will talk about the mass and charge of neutrons and how you can find the number of electrons in an atom.
Generally, the atomic structure consists of a positively charged nucleus (consisting of protons and neutrons) holding together the negatively charged electrons in the orbitals with a strong binding force.
What is the Correct Symbol for a Neutron
Since neutron is a subatomic particle with no electric charge, its symbol is n or n0. To use a more accurate symbol, the nuclear symbol for a neutron is 0n1, which again indicates that they are neutral or charge fewer particles and have slightly higher mass as compared to protons.
Mass of Protons Neutrons and Electrons
Following are the masses of Protons, Neutrons and Electrons :
Protons: 1.6726219 × 10-27 kilograms. This is called one atomic mass unit (or amu)
Neutrons: The mass of neutron cannot be determined due to its zero (or neutral) charge. But it is slightly greater than protons.
Electrons: The mass of electrons is approximately 9.109×10−31 kilograms.
