An element which has seven valence electrons is placed inGroup 14Group 15Group 16Group 17

The group number, number of valence electrons, and valency of an element with the atomicnumber 15, respectively, are:(a) 16, 5 and 2 (b) 15, 5 and 3 (c) 16, 6 and 3 (d) 15, 6 and 2

he number of valence electrons found in an atom of a group A element is equal to:  its atomic number   its mass number   it group number   eight

The Lewis dot structure of the element N (Group VA) will contain   seven valence electrons.

) What is the relationship between the group number and the number of valency electrons?

Explain how the group in which an element is located relates to the number of valence electrons in its outer shell.
