Question

Valence electrons are found by looking at what _________________ the atom is in on the periodic table. 

Answer 1

Valence electrons are found by looking at what energy level the atom is on the periodic table. These valence electrons are the outermost electrons which can greatly impact the properties of the atoms. They are the most important electrons from the atoms, because they determine the function and the reactivity of an atom.

Answer 2

Valence electrons are found by looking at what  Group the atom is in on the periodic table.
When electron is associated with an atom, they will form a chemical bond. and atoms with a similar number of the electron are a group within every Periodic Table because they all have similar bonding behavior.
