For an element x, it is given that atomic number = 17 and mass number =35. Write the electronic configuration of the element x. Find its valency. Is it a metal;or non metal
Dear student,
The electronic configuration:
As the valence shell has 7 electrons
Therefore, valency = 8-7=1
The above element is a Non-metal because it has more than 3 electrons in it's valence shell.
Regards
The electronic configuration:
Atomic no. | K | L | M |
---|---|---|---|
17 | 2 | 8 | 7 |
Therefore, valency = 8-7=1
The above element is a Non-metal because it has more than 3 electrons in it's valence shell.
Regards
