The number and arrangement of electrons in an atom governs its chemical activity.
The nucleus of an atom contains protons and electrons.
The positive charges of an element are carried by the electrons.
The neutral charges of an element are carried by the protons
An element may be composed of several types of atoms
An atom is comprised of subatomic particles. The protons bear a positive charge, are found in the nucleus, and their number creates the atomic number assigned to that element. The neutrons are found in the nucleus as well and they with the protons create the majority of an atom's mass. The electrons bear a negative charge and govern the elements reactivity.
The positive hydrogen forms a hydrogen bond with the negative oxygen from a nearby molecule. No electron transfer or sharing is occurring in this type of bond. It is a weak attraction between polar molecules.
Saturated fats have no double bonds between the carbon atoms. They are linked to the promotion of a build up of fat material known as plaque in a person's blood vessels in a disease known as atherosclerosis.
