Does the atomic number represent electrons?
The atomic number uniquely identifies a chemical element. It is identical to the charge number of the nucleus. In an uncharged atom, the atomic number is also equal to the number of electrons. The sum of the atomic number Z and the number of neutrons N gives the mass number A of an atom.
Do nuclei have energy levels?
The nucleus, like the atom, has discrete energy levels whose location and properties are governed by the rules of quantum mechanics. The locations of the excited states differ for each nucleus. The excitation energy, Ex, depends on the internal structure of each nucleus.
What do you mean by spin active nuclei?
I thought that only way a nucleus can be NMR active is when the atom has an odd mass, which means that there is an odd number of protons or neutrons and an even number of the other particle.
What is the most powerful nuclear weapon now?
Tsar Bomba
Is Poseidon bomb real?
The Poseidon (Russian: Посейдон, “Poseidon”, NATO reporting name Kanyon), previously known by Russian codename Status-6 (Russian: Статус-6), is an autonomous, nuclear-powered, and nuclear-armed unmanned underwater vehicle under development by Rubin Design Bureau, capable of delivering both conventional and nuclear …

Can a nuclear weapon cause a tsunami?
The tests revealed that a single explosion would not produce a tsunami, but concluded that a line of 2,000,000 kg (4,400,000 lb) of explosives about 8 km (5.0 mi) off the coast could create a destructive wave.
What is the world’s largest torpedo?
Poseidon
What weapon does Poseidon yield?
Poseidon 2M39 torpedo is an autonomous, nuclear-powered unmanned underwater vehicle armed with a nuclear warhead that could bypass most of the shore-based defenses. According to CNN, the West, especially the US, has expressed concern about the Russian super-weapon.
What is the fastest submarine?
Soviet submarine K-222
What really sank the Kursk?
Racked by explosions, Kursk sank in 354 feet of water at a 20-degree vertical angle. One of the explosions ripped a large gash in her forward bow, near the torpedo compartment. The explosion was likely caused by a faulty weld that failed to hold the hydrogen peroxide fuel chamber together.
How fast can submarines go underwater?
How Fast Can a Submarine Go? This is classified as well. However, U.S. nuclear-powered submarines can go faster than 23 miles per hour, which is 37 kilometers per hour or 20 knots (nautical miles per hour) underwater.
How dangerous are submarines?
The underwater environment is a dangerous one. Submarines face many perils of the deep. Even a small fire or gas leak inside a submerged submarine can have catastrophic consequences. A collision with another vessel or grounding may be much more serious for a submarine than for a surface ship.
