"np" on the Periodic Table usually stands for the number of electrons in the outermost energy level of an element. It is used to represent the valence electrons of an element.
There is only one N and it stands for nitrogen. However there are other elements that start with N such as Neon (Ne), Nickel (Ni), Neodymium (Nd), Sodium (symbol: Na), neobium (Nb), Nobilium (No), neptunium (Np).
The 14 elements following actinium on the periodic table are called the actinides. These elements all have similar chemical properties and are part of the f-block of the periodic table.
Neptunium's symbol is Np because it is named after the planet Neptune. It is a synthetic element not found in nature and was named after Neptune due to its proximity in the periodic table to uranium, which is named after the planet Uranus.
Actinides are the elements that occupy the 5f block of the periodic table. They come after the lanthanides and are located in the bottom two rows of the periodic table. These elements are all radioactive and have similar chemical properties.
Curium belongs to the actinide series of elements in the periodic table. It is named after Marie and Pierre Curie, who discovered radium and polonium. The element curium itself does not have any family members, as it is a synthetic element with no naturally occurring isotopes.
Neptunium (Np)
there is no element with the symbol Nl. However, Ni is nickel, N is nitrogen, Np is neptunium, Ne is neon, Nb is neobium, Na is sodium, Nd is neodymium, No is nobelium. I guess that the question is Ni for nickel.
The element with chemical symbol Np is Neptunium. Neptunium is a radioactive Lanthanide and is part of the unofficial Promethium family. It has 93 electrons in 7 shells and is next to Uranium and Plutonium.
There is only one N and it stands for nitrogen. However there are other elements that start with N such as Neon (Ne), Nickel (Ni), Neodymium (Nd), Sodium (symbol: Na), neobium (Nb), Nobilium (No), neptunium (Np).
The 93rd element in the periodic table of elements is Neptunium (Np). It is a radioactive actinide metal that is primarily used in nuclear reactors and for scientific research purposes.
NP stands for Nondeterministic Polynomial.

I believe NS means non-smoker, and NP means no pets.
