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 is a condition that causes inflammation that damages medium and large arteries, many of which provide blood to the head and temples, causing temporal headache. Temporal headache is located in the temples and is characterized by an aching, continuous pain with mild to moderate intensity.Sufferers of temporal arteritis are generally in their 60s and older and are predominately Caucasian.emporal headache is located in the temples and is characterized by an aching, continuous pain with mild to moderate intensity.
