Detailed explanation-1: -Carbon-13 is one of the 3 isotopes of the element Carbon. It has exactly 6 protons, 7 neutrons and 6 electrons. The number of protons and electrons are always the same in an atom.
Detailed explanation-2: -Carbon atoms with 7 neutrons have an atomic mass of 13 (6 protons + 7 neutrons = 13). These atoms are the isotope called carbon-13.
Detailed explanation-3: -The atomic mass of an atom with 6 protons, 6 electrons, and 7 neutrons would be 13. The atomic mass is equal to the number of protons and neutrons in the atom, which in this case is 6 + 7 = 13.
Detailed explanation-4: -For example, carbon has six protons and is atomic number 6. Carbon occurs naturally in three isotopes: carbon 12, which has 6 neutrons (plus 6 protons equals 12), carbon 13, which has 7 neutrons, and carbon 14, which has 8 neutrons.
Detailed explanation-5: -The charge of an element is the number of protons in the nucleus. In this case, the element has six protons and seven neutrons. Therefore, the charge of the element is six.
