Each substance can be used once, more than once, or not at all. (in simple terms, it refers to how much an element loves an electron), Electronegativity is the tendency for an atom to attract electrons to itself, Electropositivity is the tendency for an atom to lose an electron, - Have the same atomic number (number of protons) but different mass number or different number of neutrons, low densities and melting points - these increases down the group, reacts easily in air so they're kept in oil, loses one outermost electron to form an ion of +1 charge eg. When chlorine gas is bubbled through a colorless solution of potassium iodide, it turns brown and finally a black precipitate of iodine is formed. 25 Newton.
