Uranium is a radioactive element that is highly unstable and it has a half-life of 4.5 billion years. Uranium comes in many different forms (shown below). Looking at the nuclear notations below, what is the neutron number of both of the elements below? What is the relationship of the two elements below?
A: U-235 has 235 neutrons, U-238 has 238 neutrons and they are isotopes of each other.
B: U-235 has 143 neutrons, U-238 has 146 neutrons and they are isotopes of each other.
C: U-235 has 235 neutrons, U-238 has 238 neutrons and they are ions of each other.
D: U-235 and U-238 have 92 neutrons and they are ions of each other.

Explanation:it just is

U-235 has 235 neutrons, U-238 has 238 neutrons and they are ions of each other. So the correct option is C.

What is uranium?

Since more than 60 years ago, uranium, a heavy metal, has been employed as a plentiful source of concentrated energy. Uranium is as prevalent in the Earth's crust as tin, tungsten, and molybdenum, and it can be found in most rocks in quantities of 2 to 4 parts per million.

Seawater contains uranium, which may be extracted from the seas. German scientist Martin Klaproth made the discovery of uranium in the mineral pitchblende in 1789. Following the discovery of the planet Uranus eight years earlier, it was given that name.

In supernovae, uranium is thought to have been created around 6.6 billion years ago. Even though slow radioactive decay is uncommon in the solar system, it is the primary source of heat inside the Earth today, creating convection and continental drift.

Due to its great density, uranium is also used as radiation shielding, as counterweights for aviation control surfaces, and in boat keels. The melting point of uranium is 1132 °C. Uranium has the chemical symbol U.

Therefore the correct option is C.
