the properties of proton,neutron,electron?
Answers
Answer:
Proton
Neutron
Electron
They are positively charged They are neutral They are negatively charged
They are present in the nucleus of all atoms They are present in the nucleus of all atoms except hydrogen They are present in the outer shells within an atom and orbit the positively charged nucleus in well-defined orbits
The mass of the proton is taken as one unit and equals the mass of a neutron The mass of the neutron is considered as one unit and it equals the mass of a proton The mass of an electron is about 1/2000 times the mass of a hydrogen atom
A proton is represented as “p” A neutron is represented as “n” An electron is represented as “e
Explanation:
Protons
They are positively charged particles
Charge on protons is +1. Mass of protons is 1.6727×10−27kg
Electrons
They are negatively charged particles.
Charge on electrons is -1. Mass of electrons is 9.1×10−31 kg.
Neutrons
They are neutral particles.
They have no charge. Mass of neutrons is 1.675×10−27 kg
