No piercing is considered fully healed until it's a year old. Contrary to what you may read, it takes the body a full year to season a piercing to the point where it can be removed for extended periods of time without the risk of the piercing closing.
HBr is polar. The Lewis structure shows a central carbon atom forming four single covalent bonds with the four terminal bromines. The central carbon has no lone pairs and four bonding pairs, so the molecular geometry is tetrahedral (as is the electron geometry), and bond angles are thus approximately 109.5 degrees.
Molecular geometry is the name of the geometry used to describe the shape of a molecule. The electron-pair geometry provides a guide to the bond angles of between a terminal-central-terminal atom in a compound. The molecular geometry is the shape of the molecule.
