Question

what is the valency of the element having total of 8 electrons?explain
a)2
b)1
c)0
d)6​

Answer 1

Hey...there is it answer...

(c)0

Answer 2

Answer:

Explanation:

Valence electrons are the total number of electrons present in the outermost shell of an atom, whereas valency is the combining capacity of an element to form the bonds with the other elements.

In a periodic table, the number of valence electrons increases from left to right. Suppose, if the number of valence electrons of an element is equal to 4 ie similar to of carbon,then the element will also have the same valency as 4.

Example - The atomic number of oxygen is 8, where its electronic configuration is 2,6. Oxygen has six electrons in its outermost shell and needs two more electrons to complete its octet state. Thus, oxygen has 6 valence electrons and 2 as its valency .
