Question

Compare the properties of protons, electrons and neutrons.

Answer 1

Hint: Atoms are the basic unit of matter and are made up of even smaller subatomic particles called the protons, electrons, and neutrons. These subatomic particles are present in different numbers in different types of elements.
Complete answer step by step:
The comparison of the properties of the subatomic particles: protons, electrons and neutrons are shown below:

PROTONS	NEUTRON	ELECTRONS
1. Protons are the subatomic particles that are found in the nucleus of an atom.	1. Neutrons are the subatomic particles that are found in the nucleus of an atom, except that of hydrogen.	1. Electrons are the subatomic particles that surround the nucleus in orbits.
2. Protons have a positive electrical charge of $+1$ e or $1.60217 \times {10}^{-19} C$.	2. Neutrons do not have any charge on them.	2. Electrons have a negative electrical charge of $-1 e$ or $1.60217 \times {10}^{-19} C$.
3. The mass of a proton is 1 amu which is about $1.67 \times {10}^{-27} kg$.	3. The mass of a neutron is slightly greater than that of a proton which is 1 amu which is about $1.67 \times {10}^{-27} kg$.	3. The mass of an electron is only ${\cfrac { 1 }{ 2000 }}^{th}$ the mass of a proton or a neutron.
4. The no. of protons in an atom is equal to the no. of electrons in an atom so that the atoms are electrically neutral.	4. The no. of neutrons in an atom is the difference of the mass number of the atom (M) and the atomic no. (Z).	4. The no. of electrons in an atom is equal to the no. of protons in an atom so that the atoms are electrically neutral.
5. The mass no. of an atom is the sum of the no. of neutrons and protons in it.	5. The mass no. of an atom is the sum of the no. of neutrons and protons in it.	5. The no. of electrons in atom is equal to the atomic number of the atom.

Note: As we know proton is a subatomic particle that is present in the nucleus having mass of and a charge of +1, but a positron is a subatomic particle having mass equal to electron(but a positive charge of +1). A positron is an antielectron or antiparticle counterpart of an electron. Make sure you do not confuse between the two.
