The bombers that dropped both atomic bombs flew from the island of Tinian. This was also the base for bombers that flew many of the "thousand plane" firebombing attacks every night (each of which did similar damage to the atomic bombs).
The attacks killed hundreds of thousands of innocent civilians to end the war.
These values are similar.
Bexause its similar with the atomic mass
Both have two valence electrons had hence similar properties.
The attacks killed hundreds of thousands of innocent civilians. Anytime you kill civilians, it's going to be controversial.
In an atom, the number of protons is always similar to its atomic number. (The number of nutrons may be similar or different.)
Element S has similar properties to element T but has a lower atomic number.
The Bohr atomic model is similar to solar system.
None. The only country ever attacked with atomic bombs was Japan just before the end of WW2.
The two atomic bomb attacks on Japan were in August 1945 (the 6th and 9th, to be exact).
Atomic bombs have only been used in combat twice. The US dropped two bombs, one on Nagasaki, one on Hiroshima.
