Review Matter is everything around you. Matter is composed of elements. Atoms are the smallest unit of an
element. Atoms are made of smaller subatomic
particles-protons (+ charge), neutrons (no charge), and
electrons (- charge)
More notes on atoms: Protons are positively charged (+)
and found in the ______ (the center). _______ do not hold a charge (neutral)
and are found in the nucleus. Electrons are negatively charged and
spin _______the nucleus.
More notes on atoms: Protons are positively charged (+)
and found in the nucleus (the center). Neutrons do not hold a charge
(neutral) and are found in the nucleus.
Electrons are negatively charged and spin around the nucleus.
A magnet formed by a current passed through a wire coiled around a core magnetic material; the current magnetizes the core
A safety feature in an electrical circuit that interrupts the circuit if the circuit goes beyond a safe level.
An accidental connection of low resistance made between points in a circuit in which electric currents can flow; it prevents the circuit from working as it is supposed to work.
