Question

Activity 1: Give or Take. Write the valence electron of the elements involved. Decide if
it is better for the element to give up or share their valence electron in order to become
stable.
​

Answer 1

Answer:

eight electrons

Most of the elements important in biology need eight electrons in their outermost shell in order to be stable, and this rule of thumb is known as the octet rule. Some atoms can be stable with an octet even though their valence shell is the 3n shell, which can hold up to 18 electrons.
