Why the radium rays not passed through the graphite

Answer 1

Answer:

Because graphite has many layers of carbon atoms in it. So Radium rays can't pass through it.

Graphite has a giant covalent structure in which, each carbon atom is joined to three other carbon atoms by covalent bonds. the carbon atoms form layers with a hexagonal arrangement of atoms. the layers have weak forces between them.
