protons and electrons is the same in an atom Centre of an atom is the nucleus Composed of protons neutrons and electrons Protons are positively charged particles Electrons are negatively charged particles and reside in shells surrounding the nucleus Neutrons do not carry any charge Chapter 3 Vitamins Fat soluble are nonpolar such as Vitamin A D E and K 0 Water soluble are polar such as Vitamin B and C The shape of H20 water Electrons are more attracted to oxygen atom than hydrogen atom Bond pair of electrons is not equally shared 0 Bond pair of electrons will be drawn nearer to
