A nuclear weapon (also known as an atom bomb, atomic bomb, nuclear bomb or nuclear warhead, and colloquially as an A-bomb or nuke) is an explosive device that derives its destructive force from nuclear reactions, either fission (fission bomb) or from a combination of fission and fusion reactions (thermonuclear bomb).
Was the atomic bomb the first nuclear bomb?
On 16 July 1945, the ‘Trinity’ nuclear test plunged humanity into the so-called Atomic Age. The first-ever nuclear bomb was detonated in New Mexico, at the Alamogordo Test Range. Nicknamed the “gadget”, the plutonium-based implosion-type device yielded 19 kilotons, creating a crater over 300 metres wide.
When was the last time a nuclear bomb was used?
During the final stages of World War II in 1945, the United States conducted atomic raids on the Japanese cities of Hiroshima and Nagasaki, the first on August 6, 1945, and the second on August 9, 1945. These two events were the only times nuclear weapons have been used in combat.

Since the first nuclear test explosion on July 16, 1945, at least eight nations have detonated 2,056 nuclear test explosions at dozens of test sites, including Lop Nor in China, the atolls of the Pacific, Nevada, Algeria where France conducted its first nuclear device, western Australia where the U.K. exploded nuclear …
How many times have nuclear bombs been used in war?
The dangers from such weapons arise from their very existence. Although nuclear weapons have only been used twice in warfare—in the bombings of Hiroshima and Nagasaki in 1945—about 13,400 reportedly remain in our world today and there have been over 2,000 nuclear tests conducted to date.
What was the name of the first nuclear bomb?
On August 6, 1945, the United States dropped its first atomic bomb from a B-29 bomber plane called the Enola Gay over the city of Hiroshima, Japan. The “Little Boy” exploded with about 13 kilotons of force, leveling five square miles of the city and killing 80,000 people instantly.

Are atomic and nuclear bombs the same thing?
1. A nuclear bomb is a bomb that uses nuclear fission which is the splitting of an atom into two or more particles and nuclear fusion which is the fusion of two or more atoms into one large one while an atomic bomb is a type of nuclear bomb that uses nuclear fission.
Why is it called an atomic bomb?
atomic bomb, also called atom bomb, weapon with great explosive power that results from the sudden release of energy upon the splitting, or fission, of the nuclei of a heavy element such as plutonium or uranium.
Can a fridge save you from a nuke?
GEORGE LUCAS IS WRONG: You Can’t Survive A Nuclear Bomb By Hiding In A Fridge. … “The odds of surviving that refrigerator — from a lot of scientists — are about 50-50,” Lucas said.
Is hydrogen bomb worse than nuclear?
hydrogen bomb has the potential to be 1,000 times more powerful than an atomic bomb, according to several nuclear experts. An atomic bomb works through nuclear fission, which is the splitting of large atoms like Uranium or Plutonium into smaller ones.

Why did the US drop the atomic bomb?
The explicit reason was to swiftly end the war with Japan. But it was also intended to send a message to the Soviets. Ever since America dropped a second atomic bomb on Nagasaki, Japan on August 9, 1945, the question has persisted: Was that magnitude of death and destruction really needed to end World War II?
Why was the first atomic bomb called Trinity?
Robert Oppenheimer chose to name this the “Trinity” test, a name inspired by the poems of John Donne. The site chosen was a remote corner on the Alamagordo Bombing Range known as the “Jornada del Muerto,” or “Journey of Death,” 210 miles south of Los Alamos.

When was the first atomic bomb?
The world’s first nuclear explosion occurred on July 16, 1945, when a plutonium implosion device was tested at a site located 210 miles south of Los Alamos, New Mexico, on the barren plains of the Alamogordo Bombing Range, known as the Jornada del Muerto.
