The oxygen in the water molecule attracts the most electrons and in so doing attracts a slightly negative charge.
They help pump blood at a greater distance than Atria can.
Well, first off it tells you the number of valence electrons (because that’s what those are valence electrons) it also tells you how that atom is going to bond with other atoms (whether it will tend to loose or gain electrons when in chemical bonds). It also can show how reactive an element is (if it has eight or in some cases two then it won’t react because that outer shell is full)...basically it tells you the chemical properties of that atom
The answer is a) Baking soda!
