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.
what is the difference between electron geometry and molecular geometry electron geometry is the geometrical arrangement of the electron groups around the central atom. The molecular geometry is the geometrical arrangement of the atoms around the central atom under what circumstances are electron geometry and molecular geometry not the same the electron geometry and the molecular geometry are the same when every electron group bonds two atoms together. However, the presence of lone pairs gives a difference molecular geometry than electron geometry eg and mg of four electron groups overall with 3 bonding and 1 lone pair eg= tetrahedral
