Why do elements in the first group and 17th group elements show the same valency?
Asked by Ganesh | 16th Oct, 2017, 06:50: AM
Valency is the combining capacity of the elements.
First group elements are alkali metals which give away one electron while combining (bonding) with other element.
17th group elements are halogens which accept one electron while combining (bonding) with other element.
Oxidation state of alkali metals is +1 and that of halogens is -1.
But, valency does not have any sign as it is just combining capacity of that element, hence valency of both alkali metals and halogens is same i.e. 1.

- name the element in correct order of their increasing atom atomic numbers present in the first second and third short period of the periodic table state each element electronic configuration
- groups and periods funda in periodic table
- How can I self study any chapter with clear conceptual understanding the particular chapter that is not taught in school and without the help of online videos??
- why is the periodic table named as it is?
- an alkali metal in period 3 and halogen in period 2
