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.
Temporal arteritis. Temporal arteritisis inflammation and damage to the blood vessels that supply blood to the head, neck, upper body and arms. It is also called giant cell arteritis. Arteritis-temporal; Cranial arteritis; Giant cell arteritis.Temporal arteritis affects medium-to-large arteries. It causes inflammation, swelling, tenderness, and damage to the blood vessels that supply blood to the head, neck, upper body and arms.It most commonly occurs in the arteries around the temples (temporal arteries) that branch off from the carotid artery in the neck.emporal arteritis. Temporal arteritisis inflammation and damage to the blood vessels that supply blood to the head, neck, upper body and arms. It is also called giant cell arteritis. Arteritis-temporal; Cranial arteritis; Giant cell arteritis.
