Question

How is the electron configuration of an atom related to its reactivity?

Answer 1

The valence electrons are the electrons in the outermost electronshell of an atom. This tendency is called the octet rule, because the bonded atoms have eight valence electrons. METALS. The most reactive kind of metallic element is a metal from Group 1 (e.g., sodium or potassium).

hope it helps you :-)

pls mark it at the brainliest

thank you.

Answer 2

because electronic configuration is the no electrons that an element can share and reactivity also means how many electrons it can react with .I think this may help u
