In a supernova explosion, neutron capture reactions take place, leading to the formation of heavy elements. There are two processes of neutron capture called rapid process (r-process) and the slow process (s-process) so these reactions lead to formation of different elements like: silicon, sulfur, chlorine, argon, sodium, potassium, calcium, scandium, titanium and iron peak elements (around mass number A=60): vanadium, chromium, manganese, iron, cobalt and nickel; gold, platinum, lead, hydrogen, oxygen are also formed. Radioactive titanium-44 in supernova remnant 1987A have been detected for the first time.

What kind of electrical charge does a neutron carry?
The neutrons doesn't carry a charge.They're neutral - that's why they're called "neutrons".A neutron has no charge. That is why it is called a neutron, because it is neutral.
What is the kind of collision produces the greatest force of impact?
Head-on collision produces the greatest force of impact.
Which kind of motion produces sound?
frictionfull force
What kind of force produces a constant acceleration?
a constant force.
In a standing wave what kind of interference produces the crests and the nodes?
55
What kind of elements have electron and proton and neutron?
All of the elements have protons and electrons, and all elements except hydrogen have neutrons.
Are pulsars a kind of neutron star?
Pulsars are not only a kind of neutron star, they are neutron stars. See related question.
What kind of charge does a neutron have?
A neutron does not have a charge -- its neutral
Can annihilation of matter occur between a positron and neutron?
No, a positron cannot react with a neutron in any kind of annihilation reaction. An electron and a positron can, and the same with a neutron and an anti-neutron, but it does not occur between a positron and a neutron.
What kind of star is neptune?
Negative neutron star
What kind of chage does a neutron have?
Neutral. Not positive, and not negative
What kind of atom has sixteen protons and neutrons?
None...i think Atomic number 16 is Oxygen I think...chemistry was 40 years ago! If I remember correctly it's nucleus is composed of 16 protons and ONE neutron. Having one neutron is standard for all naturally occurring elements.
What kind of decay is it when a nuclear reaction in which a neutron is transformed into a proton and in electron?
When a neutron -> proton, it is called a Beta - (minus) decay.
What kind of electrical charge does a neutron carry?
The neutrons doesn't carry a charge.They're neutral - that's why they're called "neutrons".A neutron has no charge. That is why it is called a neutron, because it is neutral.
What kind of particles are found in the nucleus of an atom?
proton neutron
What does initiation of nuclear weapons mean?
starting the fission neutron chain reaction using some kind of pulsed neutron source.
Are newly discovered elements products of combustion?
Newly discovered elements, those odd trans-uranium metals that inhabit the extreme upper end of the periodic table, are notproducts of combustion. Combustion is, in general, a chemical process. Only a nuclear process of some kind can create these ultra-heavy elements. We know that the elements up through uranium are created in stars (with the trans-iron elements created in supernovae). The heaviest elements, those that are most recelty discovered, were created by man.We use some kind of nuclear accelerator (like a cyclotron, for example) to launch particles or heavy nuclei at samples of the heaviest elements. This can result in having those target nuclei capture the particles or heavy ions and change into a yet heavier element. Additionally, continuous bombardment produces heavier still nuclei (along with a good bit of radiation).
