When two atoms bonded by a covalent bond have the same electronegativity the electrons will be equally shared. This is called pure (non-polar) covalent bonding. For example, the chlorine molecule, Cl 2.or example, sodium (a metal) combining with chlorine (a non-metal). Covalent, polar covalent and ionic bonding can be considered as forming a spectrum.As the difference in electronegativity increases the bonds become more polar then ionic. 1  Page. 2  1. 3  2. 4  3.
For the vein, see Superficial temporal vein. In human anatomy, the superficial temporal artery is a major artery of the head. It arises from the external carotid artery when it bifurcates into the superficial temporal artery and maxillary artery. Its pulse is palpable superior to the zygomatic arch, anterior and superior to the tragus.
The term temporal arteritis literally means inflammation of the temporal arteries.. As implied by the name, these blood vessels run along the temples after they branch off from the carotid artery in the neck.They provide the blood supply to portions of the scalp, jaw muscles, and salivary glands.s implied by the name, these blood vessels run along the temples after they branch off from the carotid artery in the neck.
