Question

Name the particle ${}_0{}^1\mathrm{n}$ , stating clearly the meaning of the numbers represented in super-script and sub-script.

Answer 1

• A subscript or a superscript is a character that is set slightly below and above the normal line of type respectively.
• The given particle is neutron.
• Neutron is a charge less subatomic particle found inside the nucleus. It is represented by ‘n’. It was discovered James Chadwick.
• The superscript number represents their mass number which is given as 1.
• Mass number is the sum of protons and neutrons. Here we have only one neutron and hence the mass number is 1.
• The subscript shows their charge. We know that neutron is a charge-less subatomic particle. Hence its charge is given as 0.
