Every element on the Periodic Table has an OXIDATION NUMBER of zero, including Lithium.
Strontium is located in group 2 of the periodic table. Hence it has two valence electrons. The oxidation number atomic strontium is 0 where that of strontium ion is +2.
All alkali metals easily obtain +1 oxidation state. They are in group 1 of periodic table. They donate their outermost electron to form a positive ion which has +1 oxidation status.
In the older versions of the periodic table, group VIIA corresponds to the current group 17, the halogens.
Group 1 elements are the most electropositive in nature and have only 1 valence electron. So, they always show the oxidation state of +1.
-1.

The vertical columns of the periodic table are called groups. The horizontal rows of the periodic table are called periods. The number of electron shells an atom has corresponds to the number period of the periodic table it is located in. The oxidation number or number of valence electrons an atom is depicted by the group it is in. For example: Calcium (Ca) has an oxidation number of +2 and has 2 valence electrons( outermost electrons) which means it belongs to group 2 of the periodic table called the "alkali earth metals".
the oxidation number, determined by its group on the periodic table.
I think what you are asking is about is which group on the periodic table has elements with an oxidation number of -1 in most ionic compounds. That is the 17th group - the halogens.
the oxidation number, determined by its group on the periodic table.
Every element on the Periodic Table has an OXIDATION NUMBER of zero, including Lithium.
Fermium (Fm) is in Group 7 in the Periodic Table.
Strontium is located in group 2 of the periodic table. Hence it has two valence electrons. The oxidation number atomic strontium is 0 where that of strontium ion is +2.
Oxygen is a non-metal in the group 6A of the periodic table.
All alkali metals easily obtain +1 oxidation state. They are in group 1 of periodic table. They donate their outermost electron to form a positive ion which has +1 oxidation status.
In the older versions of the periodic table, group VIIA corresponds to the current group 17, the halogens.
