How is valency measured?

Answer 1

using the Periodic Table, you look at the number at the top of the column or group that the atom is in, say...... francium is in column 1 and row 7. since it's in column 1 it has 1 valance electron. and since its in row 7 it has 7 levels of electrons.

Answer 2

Valency is measured based on the number of electrons that an atom can gain, lose, or share to attain a stable electron configuration. It is determined by the number of valence electrons in an atom's outer shell. The valency of an element can also be determined by looking at its position on the periodic table.

Answer 3

In order to find the valance of an element, you must plot out the element's Protons/Atomic # using the Bohr Diagram. The number of protons on the outermost ring is your answer.
