Why was a source of neutrons needed in the detomation of the atomic bombs?

To get the chain reaction started at the right time relative to the assembly of the supercritical mass. Like ignition timing in a car's engine, you don't want it too early or too late.
In an atomic bomb too early severely reduces yield, too late runs the risk of spontaneous fission starting the chain reaction giving melting of the bomb and a fizzle.

How do you the get neutrons?
Neutrons in an atom Equation Atomic Weight - Atomic Number = The neutrons of an element Round for the final answer Example: Sodium (Na) Atomic Number: 11 Atomic Weight: 23 23-11= 12 neutrons so therefore sodium has 12 neutrons
How many neutron in darstadium?
Atomic Weight - Atomic Number 269-110=159 Therefore Darstadium (Ds) has 159 neutrons Source: My my Gr. 9 science class
What atomic nucleus has the highest charge density on earth?
Hydrogen - it consists of a single (charged) proton with no (neutral) neutrons. Source: Degree in Natural Sciences
Why are isotopes needed?
- cancers treatments- medical diagnostics- source of energy- source of radiation- age dating- tracers- nuclear energy- atomic bombsetc.
What is Alternative energy source produced from atomic reactions?
Nuclear fission is when a neutron is fired at an element with a high atomic number, which splits and releases more neutrons and energy as a result. Nuclear fusion occurs in stars and experimental reactors.

This is also known as atomic energy?
The source of atomic energy is the "binding energy" that exists in the nucleus of all atoms. This is the energy that is contained in the union of the protons and neutrons of the nucleus. When the nucleus is split apart, the binding energy is released.
What is the brief description of an atomic bomb?
A supercritical mass of fissile material rapidly assembled with explosives, then triggered by a carefully timed pulse of neutrons from a neutron source. That's about as simple and general as it gets.
What is the charge on plutonium atom?
Nuclear fission of some isotopes release a great quantity of energy. Plutonium is a fissile material (isotopes 239Pu and 241Pu); it is used in nuclear reactors and nuclear weapons. Also Pu(alpha,n)Be is a source of neutrons and Pu is used as power or heat source.
Is selenium an atomic or molecular element?
Selenium is an atomic element with 34 electrons and 34 protons. Stable versions (isotopes) have from 42 to 44 neutrons. It is necessary in very small amounts to support life, otherwise it is poisonous. Selenium at one time was the main source for transistors and diodes because of its semiconductor properties.
What is another word for nuclear source?
Atomic.
What element in period 2 has a atomic mass of 11?
Short answer: boron. Long answer: any element with 11 protons or less could theoretically have an atomic mass of 11, as the mass = Number of Protons + Neutrons, if you add/take a certain number of neutrons from the atom it will be able to have an atomic mass of 11, but some aren't possible and others are too unstable, and will decay instantly.
