Boron is a non metallic element and the only non-metal of the group 13 of the periodic table the elements.
What is the structure of boron?
Atomic Structure of Boron The nucleus of this atom consists of six neutrons and five positively charged protons. Five electrons occupy available electron shells and revolve around the nucleus. The stability of the valence electrons determines the chemical and physical properties of the element.
Is boron malleable and ductile?
1)For example, boron, like many other metalsis ductile. On the other hand, boron isn’t very dense, sharing a common physical porperty with many non-metals. 2)Another example is silicon. It is very shiny, like many metals, but like a non-metal, it is brittle, not malleable.
