Seleninyl dichloride. CopyCopied, SWAKCLHCWHYEOW-UHFFFAOYSA-N Beyond sulfur as we move down the group none of the element occur as dibromide and dichoride. That gives you the steric number (SN) — the number of bond pairs and lone pairs around the central atom. Permanent link for this species. Acta Paediatr 81:292–295. pH may be adjusted with nitric acid to 1.8 to 2.4. Selenium is a naturally occurring, solid substance that is widely but unevenly distributed in the earth's crust. Selenium deficiency is very rare in the United States and Canada. Murillo, and M. Bochmann, in. The steric number of a molecule is the number of atoms bonded to the central atom of a molecule (σ sigma bond) plus the number of lone pairs on the central atom.
