Explanation:
Detailed explanation-1: -A neutral atom of Carbon-12 contains six protons, six neutrons, and six electrons; therefore, it has a mass number of 12 (six protons plus six neutrons).
Detailed explanation-2: -Carbon-12: with 6 protons and 6 neutrons and an atomic mass of 12.
Detailed explanation-3: -The element carbon (C) has an atomic number of 6, which means that all neutral carbon atoms contain 6 protons and 6 electrons. In a typical sample of carbon-containing material, 98.89% of the carbon atoms also contain 6 neutrons, so each has a mass number of 12.
Detailed explanation-4: -It has an atomic number of 6. That means a carbon atom has 6 protons, 6 neutrons, and 6 electrons.
