True. Protons and neutrons make up the nucleus while electrons orbit around the nucleus.
True. Matter consists of the materials mentioned in the previous answer, and those items take up space however small that space is.
True. For example, Carbon is atomic number 6 and it has 6 protons.
False. Not all 118 elements on the periodic table are found in nature. Some elements are only possible in the laboratory.
False. The number of atoms is incredibly huge. A small tiny speck of matter consists of quadrillions of atoms. 1 quadrillion = 1.0 * 10^15, which means there are 15 zeros in the number. So 1 quadrillion = 1,000,000,000,000,000.
