Question
Write the electronic configuration of the element with atomic number 17. Indicate the valency of the element.
✓
Answer
Atomic No. = 17
E.C. = (2, 8, 7)
Valency = 8 - no. of valence electrons
Valency = 8 - 7
Valency = 1
E.C. = (2, 8, 7)
Valency = 8 - no. of valence electrons
Valency = 8 - 7
Valency = 1
