Group 17 elements are also known as halogens. Atomic halogens have 0 as their oxidation number. They tend to accept an electron from another element to become stable: the new oxidation state would be -1.
The oxidation number of group 18 is 0 because they are already stable elements. Therefore, they do not need to gain or lose any electrons.
-2 is the most common in its compounds, but other oxidation numbers ranging from -2 to +6 are also possible for many of the elements. KEEP CALM AND ROLL TIDE
+1 for the alkali metals (Group 1) - Li, Na, K, Rb and Cs.
going in order from left to right the oxidations number go from +1. +2. +1 or +2 ( for groups 3-12.) +3. + or - 4 -3. -2. -1. + or - 0
Group 17 contains halogen. All of them shows -1 oxidation number.
Group 14 is in the p block. Generally it shows +4 oxidation number.
2 is the most common oxidation number.
noble gases
+2
In the older versions of the periodic table, group VIIA corresponds to the current group 17, the halogens.
Group 9
A group in periodic table is the column of element in periodic table
The alkali metals are group 1, also known as group 1A.
The number of shells in periodic table increase down the group, i.e., vertically.
yes. that group on the periodic table is consisted of noble gases
Fermium (Fm) is in Group 7 in the Periodic Table.
Oxygen is a non-metal in the group 6A of the periodic table.
In the older versions of the periodic table, group VIIA corresponds to the current group 17, the halogens.
Group 1 elements are alkali metals. Group-18 elements are inert in nature.
Indium in the periodic table: group 13, period 5, atomic number 49.
Sodium, Na, is in group 1 period 3 on the periodic table.
