Neptunium is not combustible but pyrophoric as a powder.
Electron configuration of neptunium: [Rn]7s26d15f4
Yes, neptunium is a metallic element and can exhibit a metallic luster when polished.
The fresh surface of neptunium is silvery.
Neptunium, with the chemical symbol Np, is the chemical element with the atomic number 93.
The number of valence electrons in neptunium, which has an atomic number of 93, can be determined by looking at its electron configuration. Neptunium has a configuration of [Rn] 5f^4 6d^1 7s^2, so it has 3 valence electrons.
