WebSep 16, 2024 · This is a positive ion. It has a 1+ charge because it has lost 1 electron. That leaves a total of 8 electrons in the outer level of the nitrogen. There are therefore 4 pairs, all of which are bonding because of the four hydrogens. The ammonium ion has exactly the same shape as methane, because it has exactly the same electronic arrangement. WebCervical Spine. The neck is part of a long flexible column, known as the spinal column or backbone, which extends through most of the body. The cervical spine (neck region) consists of seven bones ( C1-C7 vertebrae ), which are separated from one another by intervertebral discs. These discs allow the spine to move freely and act as shock ...
