What is meant by valency of an element? What is the relationship between the number of valence electron and valency? Please give detailed, short answer,
10 points and a brainliest for best answer
Answers
Explanation:
Valency of an element is the number of electrons an atom loses, gains or shares with other atoms so as to complete the shell.
Valence electron is the total number of electrons present in the outermost shell of an atom.
The relation between the valency of an element and the number of valence electrons in its atoms is that, the valency of an element is either equal to the number of valence electrons in its atom or equal to the number of electrons required to complete eight electrons in the valence shell.
hope the answer will help you

Answer:
Valency is the combining power of an element. Elements in the same group of the periodic table have the same valency. The valency of an element is related to how many electrons are in the outer shell. ... V - beneath each symbol, write it's valency.
