How do you name #"Nd"_2"Fe"_(14)"B"#?

1 Answer

Neodymium-Ferro-Boron

Explanation:

Read from left to right:

#"Nd"_2# ...................... #"Fe"_(14)# ........ #"B"#

Neodymium-Ferro-Boron, otherwise known as an NdFeB magnet, constructed as an alloy of primarily neodymium, iron, and boron.

It's a rare-earth magnet compound.

  • #"Nd"# is the chemical symbol for neodymium.
  • #"Fe"# can be called by its old prefix, "ferro", though saying "iron" is fair game.
  • #"B"# is still called boron.

This website states the name in full for these kinds of magnets.

These two websites give an alternative name: Neodymium-Iron-Boron.
