Match the element or group to the rule assigning its oxidation state. (1.5 points) a. oxygen b. hydrogen c. lone elements and atoms in gases d. elements with multiple oxidation states e. elements in groups 1, 2, and 17 and polyatomic ions 0 ionic charge +1, – 1 if bonded to a diatomic metal almost always –2 determined by other elements in the compound

C. Lone elements and atoms in gases : 0

Elements in the free elemental have an oxidation number of zero

E. Elements in groups 1, 2, and 17 and polyatomic ions : Ionic charge

Group 1, 2, and 17 ions are formed by the alkali metals, alkaline metals and halogens respectively. Alkali metals, alkaline metals and halogens form +1, +2 and -1  ions respectively. Polyatiomic ions have -1, -2, -3 charges such as OH-, CO32-, PO43- respectively.

B. Hydrogen : +1, – 1 if bonded to a diatomic metal

H has an oxidation number of +1. H in metal hydrides such as NaH (sodium hydride) has an oxidation number of -1

A. Oxygen : Almost always –2  

O has an oxidation number of -2.

D. Elements with multiple oxidation states : Determined by other elements in the compound

V (vanadium) has different oxidation which depends on the compound in which V is found.

d: the voltage of the secondary coil is less than that of the primary coil.

im not suree sorry if wrong

the atomic mass is the bottom number on the element.
