Zinc's electron configuration is [Ar] 3d10 4s2. It readily loses both its 4s electrons to achieve a full d shell, resulting in an oxidation state of +2 in most of its compounds. The stable 3d10 configuration following the loss of electrons contributes to zinc's preference for the +2 oxidation state.
The oxidation number of calcium is +2, as it tends to lose two electrons to achieve a stable electron configuration. The oxidation number of chloride is -1, as it tends to gain one electron to achieve a stable electron configuration.
The oxidation number of Na is +1, as it tends to lose one electron to achieve a stable electron configuration. The oxidation number of Cl is -1, as it tends to gain one electron to achieve a stable electron configuration.
As it forms the I- ion froming an octet its most likely oxidation number is -1
The oxidation number for an atom is determined by the number of electrons it gains or loses to achieve a stable electron configuration. For the configuration 1s22s22p63s22p5, sulfur (S) has an oxidation number of -2, as it has gained two electrons to achieve a full valence shell of 8 electrons.
The oxidation number for sodium (Na) is +1. Sodium typically loses one electron to achieve a stable electron configuration.
The oxidation number of calcium is +2, as it tends to lose two electrons to achieve a stable electron configuration. The oxidation number of chloride is -1, as it tends to gain one electron to achieve a stable electron configuration.

Oxidation number of Li is +1. Oxidation number of oxygen is -2.
The oxidation number for Ra (Radium) is +2. Radium tends to lose two electrons to achieve a stable electron configuration.
The oxidation number of calcium is +2. Calcium typically loses two electrons to achieve a stable electron configuration.
+1 only for all elements (except for hydrogen) hydrogen can have +1 and -1 as their oxidation numbers.
It is in the first group. It shows only -1 number.
An oxidation number of -1 means that the element has gained one electron, indicating that it is in its reduced state (has undergone reduction). This often occurs when an element gains an electron to achieve a stable electron configuration.
0- any element by itself has an oxidation number of 0.
