The flow of electrical current is possible because electrons are a) able to move from one atom to another; the atom that loses an electron becomes positively charged and the atom that gains an electron becomes negatively charged. b) charged particles that move freely between all atoms; when an atom looses an electron it becomes negatively charged. c) negatively charged and can move between atoms; the atom that looses an electron becomes negatively charged and the atom that gains an electron becomes positively charged. d) positively charged particles that when transferred between different atoms create ions that are positively charged.
