A neutron is formed by an electron and a proton combining together. Therefore, it is neutral. For the given statement, write True or False
Answers
explanation :- there are many subatomic particles in atom. electron , proton , neutron, meson , antineutrino , neutrino etc...
obviously , mass of neutron > mass of proton > mass of electron. but it doesn't neutron is formed by an electron and a proton combining together. of course it is , but it is possible when we will talk about a special case e.g., nuclear reaction. otherwise neutron is just a subatomic neutral charged particle. neutrons are postulated neutral because in ground state of any atom contains number of electron equals number of protons.
so, we can say given statement is false.
A neutron is formed by an electron and a proton combining together. Therefore, it is neutral. This statement is FALSE.
An atom primarily consists of neutrons, protons and electrons. Neutrons and protons are present in the nucleus of an atom. Electrons revolve around the nucleus. Protons have a positive charge of +1e (e= 1.6 x 10>-19 Coulombs) and Electrons have a negative charge -1e.
Neutrons have zero charge so they are neutral particles. They are not formed by combination of electron and proton. Instead they have one up quark and two down quarks. One up quark has a charge of +2/3 e, and the two down quarks each have a charge of -1/3e. Hence, these charges cancel (+2/3e - 1/3e -1/3e = +2/3e - 2/3e = o) out and so neutrons have a neutral or zero charge.
Hope it helps!!!
