No, a neutron is a particle.
A neutron is a fundamental part of the nucleus of all atoms and is hence contained within a non metal a metal or a metalloid
When it is mixed or alloyed with beryllium, polonium can be a neutron source: beryllium releases a neutron upon absorption of an alpha particle that is supplied by 210Po. It has been used in this capacity as a neutron trigger or initiator for nuclear weapons
Lead is a metal in gunshot residue that can be detected by atomic absorption but not neutron activation. This is because atomic absorption spectroscopy relies on the absorption of light by ground-state atoms, which lead exhibits. Neutron activation analysis, on the other hand, requires the irradiation of samples with neutrons to induce radioactivity, which is not applicable to lead.
Usually boron is alloyed with steel, boron is a very good neutron absorber.
Well, a neutron activation analysis test can find this out all in a single test.
you already partly answered your own question. Neutrons.
A rare-earth metal with the symbol Dy and atomic number 66. It is a metal with a metallic silver luster and a high thermal neutron absorption cross-section. Dysprosium has seven isotopes, the most abundant of which is 164 Dy. It is used for its high thermal neutron absorption cross-section in nuclear reactors and its high magnetic susceptibility in data-storage applications.

No. A neutron carries no charge.
There is no such thing as a "positive neutron" or a "negative neutron". A neutron is always neutral.
Some applications of californium: - neutron source as Cf-Be source - neutron source for neutron activation analysis (portable installations) - neutron radiography - irradiation for some cancers treatment - nuclear fuel rod scanning - neutron source to detect water, petroleum, metals, methane etc.
James chadwick was the discoverer of neutron. He gave the famous neutron reaction.
