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.

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).
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 much of an atom volume does the nucleus make up?
how much of an atoms volume does the nucleus make up
How powerful is a hydrogen bomb?
A hydrogen bomb is approximately 4.87 times more powerful than an atom bomb. What makes these bombs so powerful is that hydrogen is an extremely inflammable and explosive gas. When the bomb is released, the special coating used on its shell captures tons of friction, which heats the bomb. Then the detonator button is pressed, and the bomb blows up. Also, if the bomb comes in contact with the ground, before the button is pressed, then the heat absorbed by the bomb will set fire to the hydrogen inside and blow the bomb up.
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?
You'd end up with a charged beryllium atom (to which you'd need to add an electron to make it neutral).
Why was the atom bomb special?
It blew up japan
How many electrons are in a beryllium ion?
The beryllium atom has 4 electrons. As with all other elements, Beryllium atoms are most stable when they have a full outer shell of electrons. Since the neutral electron configuration of the beryllium element atom is 1s2 2s2 (total of 4 electrons) the atom either needs to pick up another six electrons, thereby becoming 1s2 2s2 2p6, or lose two electrons to become 1s2.
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"
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 elements make up beryllium sulfite?
5
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).
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
Who was president when albert Einstein came up for the idea of the atom bomb?
Franklin Delano Roosevelt
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.
