## Step1For question 6, we need to identify the particle that carries a negative charge. The options are neutron, nucleus, proton, and electron. Among these, only the electron carries a negative charge.## Step2For question 7, we need to identify the number of protons in an atom of an element with an atomic number of 8. The atomic number of an element is defined as the number of protons in its nucleus. Therefore, an atom of an element with an atomic number of 8 must have 8 protons.## Step3For question 8, we need to identify what differentiates different elements. The options are electrons, protons, molecules, and atoms. Different elements are differentiated by the number of protons in their atomic nucleus. Therefore, the correct answer is protons.
