Shell of hydration - Study guides, Class notes & Summaries

Molecule Unit of matter that results when two or more atoms are joined by covalent bonds Ionic Bond A bond resulting from the electrostatic attraction of a cation for an anion. Brainpower Read More Nonpolar Covalent Bond A bond characterized by an even distribution of charge; electrons in the bonds are shared equally by the two atoms Polar Covalent Bond A bond resulting from unequal sharing of bonding pairs of electrons between atoms Polyatomic Ions Charged g...

Valency correct answers How many electrons the atom need to fill shell - Shell 1: 2e- - Shell 2: 8e- - Shell 3: 18e- Covalent bonds correct answers - Sharing of electrons between atoms of the same or different element Compound correct answers - combo of 2+ different elements Electronegativity correct answers - Atoms attraction for e- in covalent bond (EX: H2O) - Determines the distribution of e- w/in a covalent bond - higher value = stronger attraction of electrons EX: O = 3.5...

A coach has requested information about the status of an athlete's injury. What should the athletic trainer do with such a request? - Obtain written authorization from the athlete to disclose the information A patient asks the athletic trainer to modify a piece of equipment that does not fit properly. What should the athletic trainer do to limit liability? - Do not modify the equipment and do not allow the patient to play with the improperly fitted equipment. A patient has a mild form of ...
