Protons and neutrons are found in the nucleus of an atom. Traveling around the nucleus are fast-moving particles called electrons. Each electron has a negative electrical charge. An electron is much smaller and lighter than a proton or a neutron. Which of the following statements are true? Select all that apply.
Though they are too small to see without a special microscope, atoms make up all of the substances around you. Like all matter, atoms have mass and volume. But atoms are extremely small. A water droplet, like the one hanging from the tip of the leaf in this picture, contains more than a billion trillion atoms! Which of the following statements is true?
Almost all of an atom's mass is found in its nucleus, located in the center of the atom. An atom's nucleus can contain two types of particles: protons and neutrons. The nucleus of every atom contains one or more protons. Each proton has a positive electrical charge. In many atoms, the nucleus also contains neutrons. A neutron has no electrical charge. Determine whether each statement is true or false to complete the table.
