What is Nihonium?

Nihonium, the one hundred-thirteenth element on the periodic table, is a synthetic, radioactive p-block element and Japan's first contribution to the periodic table's naming.

Atomic Number: 113

Symbol: Nh

Atomic Mass: [286] u (most stable isotope)

Category: P-block (Post-Transition Metal)

State at Room Temperature: Solid

Discovered By: Kosuke Morita et al. (RIKEN, Japan, 2004)

⚛️ Atomic Structure of Nihonium

Nihonium has one hundred thirteen protons, one hundred seventy-three neutrons (in its most stable isotope, Nihonium-286), and one hundred thirteen electrons, with three in its outer shell.

  • 🟢 Protons: 113
  • 🔴 Neutrons: 173 (Most stable isotope, Nihonium-286)
  • 🟡 Electrons: 113

💡 Did you know? Nihonium's name comes from "Nihon," the Japanese word for Japan, marking a proud scientific milestone!

🔬 Nihonium Properties

Nihonium is radioactive, likely silvery, and dense. Its melting point is unknown but predicted to be lower than earlier transition metals, and it emits alpha radiation.

🧪 How Was Nihonium Discovered?

In 2004, Kosuke Morita and a team at RIKEN in Japan synthesized Nihonium by bombarding bismuth with zinc ions, with its discovery confirmed over years of experiments.

⚡ Uses of Nihonium

  • 🔬 Research: Studying superheavy element properties.
  • ⚡ Synthesis: Precursor to even heavier elements.

💡 Fun Facts About Nihonium

  • 🇯🇵 Named after Japan (Nihon).
  • ⏳ Half-life of 20 seconds.
  • 🌏 First element named by Asian scientists.
  • 🏭 Fully synthetic.

⚠️ Safety & Precautions

Nihonium is radioactive and a radiation hazard. It's only produced in trace amounts in controlled labs.
