1. a) Carbon has six protons, six neutrons, and six electrons. Oxygen has eight protons, eight neutrons, and eight electrons. Draw each of these atoms. (1 point)
HINT: Think about the smaller numbers in each element as the number of electrons and the larger as the number of protons and neutrons.

Carbon and Oxygen atoms have specific compositions of protons, neutrons, and electrons. Understanding atomic number and mass number is crucial in distinguishing elements and isotopes.

Explanation:

Carbon has 6 protons, 6 neutrons, and 6 electrons, while Oxygen has 8 protons, 8 neutrons, and 8 electrons. When drawing these atoms, carbon would have 6 electrons orbiting the nucleus, and oxygen would have 8 electrons.

In the case of carbon isotopes, carbon-12 has 6 neutrons, and carbon-14 has 8 neutrons. The atomic number of an element corresponds to the number of protons present, while the mass number is the sum of protons and neutrons within the nucleus.
