1. Elements on their own have an oxidation # equal to 0.
(ex. in the chem equation Ca + 2AgCl --> CaCl2 +2Ag, Ca and 2Ag would have oxidation #s equal to 0.)
2. Ions in ionic compounds have an oxidation # equal to their charge.
(ex. in the chem equation Ca + 2AgCl --> CaCl2 +2Ag, 2AgCl = Ag+1 and Cl-1, and CaCl2 = Ca+2 and Cl2-1.)

Oxidation number of groups in periodic table?
Group 1 elements have an oxidation number of +1, group 2 elements have an oxidation number of +2, group 17 elements have an oxidation number of -1, and group 18 elements (noble gases) have zero oxidation number since they are chemically unreactive.
How can you determine an element's Oxidation number looking at a periodic table?
To determine an element's oxidation number on the periodic table, consider its group number (vertical column). Elements in Group 1 typically have an oxidation number of +1, Group 2 is +2, Group 7 (halogens) is typically -1, and Group 6 is often -2. Transition metals have variable oxidation states based on the compound. Remember that the oxidation number is the charge an atom would have if electrons were transferred completely.
What is the oxidation number of all the elements in column 13?
The elements in column 13 of the periodic table (Group 13) typically have an oxidation number of +3 in their compounds. This includes elements such as boron, aluminum, gallium, indium, and thallium.
How can an elements Oxidation number be found?
The oxidation number of an element is typically determined based on its position on the periodic table and known oxidation rules. For example, in compounds, the sum of oxidation numbers must equal the overall charge. For atoms in their elemental form (such as O2 or Na), the oxidation number is zero.
Where is the oxidation number in the periodic table?
The oxidation number is not specifically listed on the periodic table. Oxidation numbers are assigned based on rules and guidelines that depend on the chemical properties and bonding of each element. Different elements can have multiple oxidation states, which can vary depending on the compound or molecule in which they are found.
Oxidation number of groups in periodic table?
Group 1 elements have an oxidation number of +1, group 2 elements have an oxidation number of +2, group 17 elements have an oxidation number of -1, and group 18 elements (noble gases) have zero oxidation number since they are chemically unreactive.
What is the common oxidation number for all elements in group 17 of the periodic table?
-1.

How do you find the oxidation number using the periodic table of elements?
To find the oxidation number of an element using the periodic table, you need to consider the group number for main group elements and the charge on transition metals. Main group elements typically have oxidation numbers equal to their group number, while transition metals can have multiple oxidation states indicated by Roman numerals in parentheses. Exceptions like oxygen (-2) and hydrogen (+1) exist, and the sum of oxidation numbers in a compound must equal zero.
Do all elements in a group have the same oxidation numbers?
There is at least one oxidation number shared by all the elements in a periodic table column, but some of the elements may have more than one oxidation number and some of these additional oxidation numbers may not be possible for all the elements in a column.
What is the oxidation number of gallium?
The oxidation number of gallium is typically +3. This is because gallium belongs to Group 13 of the periodic table, and elements in this group typically exhibit an oxidation state of +3 in their compounds.
What is the oxidation number of group 3 in periodic table?
Group 3 elements have an oxidation number of +3. This is because they have three valence electrons that are typically lost in chemical reactions, resulting in a +3 oxidation state.
What elements can have variable oxidation numbers are known as known as what group of elements?
Most elements can have more than one oxidation number, but I think you are looking for the transition elements in groups 3 - 12.
Where do you find the oxidation number of an element?
The oxidation number of an element can be found by referring to the periodic table and following the general rules and guidelines for assigning oxidation numbers to elements in compounds. The oxidation number reflects the charge an atom would have if all bonds were ionic.
