electricity basics

Learn electricity basics! Explore atoms, circuits, conductors, and insulators with this engaging worksheet.

Fill in the blanks with the correct word from the bank below Atoms consist of three basic particles: protons, electrons, and neutrons. The nucleus (center) of the atom contains the protons (positively charged) and the neutrons (no charge). The outermost regions of the atom are called electron shells and contain the electrons (negatively charged). Fill in the blanks with the correct word from the bank below Most of the atom is empty space. The rest consists of a positively charged nucleus of protons and neutrons surrounded by a cloud of negatively charged electrons. The nucleus is small and dense compared with the electrons, which are the lightest charged particles in nature. Electrons are attracted to any positive charge by their electric force; in an atom, electric forces bind the electrons to the nucleus. Match between items from the left column to the correct definition in the right column proton stable subatomic particle that has a positive charge nucleus in the center of the atom. consists of protons and neutrons atom The smallest unit of matter that has the characteristic properties of a chemical element electric circuit A path for transmitting electric current resistance A measure of the opposition to current flow in an electrical circuit voltage The pressure from an electrical circuit's power source that pushes charged electrons (current) through a conducting loop. current the movement of electrons through a wire. Ampere Unit of electric current in the International System of Units Electric circuits Fill in the name of the item in the circuit battery switch bulb Select an item from the list to the correct column Insulators wool rubber paper plastic nylon Conductors iron silver gold copper steel Atom structure Write down the correct name proton electron neutron
