The earliest ones all did.
Early atomic bombs used an internal initiator/neutron source to start the chain reaction. This was composed of beryllium and polonium and somewhat resembled a golfball in appearance. It was placed in the center of the bomb and when crushed by the shock from the chemical explosives, the two elements mixed, alpha particles from the polonium decay released neutrons from the beryllium which started the chain reaction.
These had a problem though: the polonium decays fairly rapidly, meaning these initiators/neutron sources had to be replaced about every 138 days to keep the bombs reliable. As the stockpile grew this became a major maintenance issue.
In the middle 1950s the US switched to external initiators/neutron sources to start the chain reaction. These are operated electrically and use tritium in a miniaturized particle accelerator to initiate a small fusion reaction reaction and a pulse of neutrons. The maintenance issues were effectively eliminated as these initiators/neutron sources only had to be replaced about every 12 years, a period of time longer than many weapons were even kept in the stockpile before being replaced by newer designs.
Some atomic bombs do use a beryllium neutron reflector on the inside of the depleted uranium tamper to improve efficiency, but this is not absolutely necessary for the bomb to work. To know whether a given bomb uses this or not would require access to classified design information.
What else can I help you with?
What is the hybridization of the central atom in BeF2?
The hybridization of the central beryllium atom in BeF2 is sp. Beryllium has two valence electrons which pair up to form two sigma bonds with the two fluorine atoms. This results in the formation of two sp hybrid orbitals.
How many different elements make up beryllium sulfite BeSO3?
The elements in beryllium sulfite can be easily determined by looking at the formula. They are beryllium (Be), sulfur (S), and oxygen (O).
What are the chemicals to make up beryllium?
Beryllium is a chemical element with the symbol Be and atomic number 4. It is a metal that is typically extracted from beryl minerals.
How many protons dose Beryllium-9 have?
The element beryllium has an atomic number of four. All atoms of this Group 2 metal, regardless of which isotope we might consider, have four protons in their nucleus. And all beryllium atoms have a +4 nuclear charge.
How many electron shells does the beryllium atom have?
Two energy shells. Made up as 1s2, 2s2 Shells 1 & 2 each have only 's' orbital and each orbital has only two electrons in it. The outer shell '2' is more energetic. The electrons are paired and spin in opposite directions to each other.
What would be formed if one proton is added to the lithium atom?
Adding one proton to a lithium atom would create a beryllium atom because the number of protons would increase from 3 to 4. This change would make the element more reactive and alter its chemical properties.
Why was the atom bomb special?
It blew up japan
How many elements make up beryllium sulfite?
Beryllium sulfite is composed of three elements: beryllium, sulfur, and oxygen.
What country was blown up in China by an atom bomb?
hiroshima
How did the US get its nuclear or atom bomb?
Look up "The Manhattan Project"
What is the name of this element BeCrO4?
There are three elements that make up the compound beryllium chromate: Be = beryllium Cr = chromium O = oxygen
What is the hybridization of the central atom in BeF2?
The hybridization of the central beryllium atom in BeF2 is sp. Beryllium has two valence electrons which pair up to form two sigma bonds with the two fluorine atoms. This results in the formation of two sp hybrid orbitals.
Why was spliting the atom nessersary for the Americains to make the bomb blow up in Hiroshima?
The atoms splitting is what causes the explosion, without the technology to cause atoms to split the bomb was just another pile of junk.
How many electrons are in a beryllium ion?
A beryllium ion, like Be2+, has lost two electrons compared to a neutral beryllium atom. A neutral beryllium atom has 4 electrons, with 2 in the inner shell and 2 in the outer shell. When it loses 2 electrons to become Be2+, it now has 2 electrons remaining, both in the inner shell.
What atom is in the atomic bomb?
There are many atoms used in an atomic bomb for various purposes.Iron and carbon, lus some others depending on preference, make up the steel casing;silicon and oxygen atoms make up the computer hardware chips;copper makes up the wiring in the bomb;various type of atoms make up the other tools used by the bomb;carbon, nitrogen and oxygen make up the conventional explosive;while plutonium and uranium atoms are used as fissionable material and hydrogen atoms as fusion material.
How many different elements make up beryllium sulfite BeSO3?
The elements in beryllium sulfite can be easily determined by looking at the formula. They are beryllium (Be), sulfur (S), and oxygen (O).
