State the given statement is true or false.
A.True
B.False

Answer 1

Hint:Neptunium is a chemical element in the periodic table with atomic number 93. Its symbol is Np. Neptunium is placed after uranium and it is the first transuranic element. Neptune is the eighth solar planet which is named after the Roman god of the sea.

Complete step by step answer:
Neptunium is placed after uranium in the periodic table. So it is known as a transuranic element.
We know that Neptune is a planet.
Neptune is in eight positions from the sun. Neptune is in between Uranus and Pluto.
So Neptune is located after the planet Uranus.
Planet Neptune is named after the Roman god of the sea.
When we consider the chemical element Neptunium, it is placed after the element uranium in the periodic table.
Neptunium is the first transuranic element.
Like the planet Neptune is located after the planet Uranus in the solar system, Neptunium is placed after the element uranium in the periodic table.
Since it is the first transuranic element discovered it got the name Neptunium.
Like the planet Neptune located between the planets Uranus and Pluto, the element Neptunium is placed between Uranium and plutonium.
These three elements uranium, neptunium, and plutonium are named after the planets Uranus, Neptune, and Pluto respectively.
Thus the element neptunium got its name from the planet Neptune.
The correct option is (A) .


Note:
 Uranium, neptunium, and plutonium are radioactive elements. The atomic number of uranium is 92. The atomic number of neptunium and plutonium is 93 and 94 respectively. Uranium got its name from the planet Uranus. In the solar system, Uranus is placed first and Uranus and Neptune are placed next. Since neptunium is the first transuranic element discovered, it got its name from the planet Neptune located after Uranus.
