Question

Which statement about valence electrons is true?

A) they are located in the outer energy level of an atom
B) they are potentially involved in chemical reactions
C) they determine whether an element can conduct electricity
D) all of the above

Answer 1

it's D because the are located in the outer most shell, they are responsible for the chemical reaction and determine if they conduct electricity or not, you can look it up if you don't believe me

Answer 2

Answer:The number of electrons in an atom's outermost valence shell governs its bonding behavior. Therefore, elements whose atoms can have the same number of valence electrons are grouped together in the periodic table of the elements

Explanation: B
