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.
HBr is polar, because H and Br have different electronegativity and HBr is not a symmetric compound. Is Hbr Polar. Polar because the Br atom pulls on the electron much harder than the H atom. This is because Br has 7 electrons and wants 8 (a full octet), while H has only one.
