Question

Define Valency and find the valency of an element whose atomic number
is 10.​

Answer 1

Answer:

If the number of electrons in the outer shell is between one to four, the compound is said to have positive valency. For compounds with electrons four, five, six, or seven, the valency is determined by subtracting the electron from eight. All noble gases except for Helium have eight electrons.
