Why can we pick things up?

I've been thinking. Our hands, to a molecular level, are made of electrons. So are other objects.When you touch an object, you're just feeling the reaction from the electrons belonging to the objects element. So if this is the case, why don't things just fly off from our hands because of atomical reactions?

The main reason is that atoms are made out of positive *and* negative charges, and the effect of the positive charges mostly cancels the effect of the negative charges. If your hand was made out of pure electrons and had no protons and you tried to grab a book made out of pure electrons, the book would indeed fly away under electrostatic repulsion. But because of the presence of positive and negative charges, the net charge in a given volume is zero. Only when you get two atoms very close to each other does the exact location of the negative and positive charges in the atom matter so that they don't completely cancel each other.

Gravity probably plays a rol and the electronic reaction between an item wee hold would not be enough and skin is not a good conucter when it comes to electricity I'm guessing
