What is the valence of the outermost 4 electrons Such as title

The highest positive price is +4 and the lowest negative price is -4
That is, between -4 and +4

What is the relationship between valence and the number of outermost electrons? 1. Is the valence of a metal element equal to the number of its outermost electrons? (Refers to unchanged valence only, e.g. sodium +1 valence) 2. Is it a negative valence nonmetallic element whose valence is equal to the opposite of the number of electrons in its outermost layer? (E.g. oxygen 8-6=2, contrary number-2) You're talking about ions, electrons, and protons. What about atoms? The number of protons is the same as the number of electrons!

The principle is not like this. The valence value is equal to the positive and negative electron difference. For example, sodium ion has 11 protons and 10 electrons. Proton is more than electron, and is positively charged. Lord you have a concept is not clear. Compound value refers to the element compound value! Not the original...
