Which of the following is the atomic number of an atom that has 12 protons and 12 neutrons?
A. 144
B. 12
C. 24
D. 1
elements are arranged on the periodic table based on their atomic number. This identity is critical in evaluating the chemical families of elements in chemistry. Atoms are made of protons, neutrons, and electrons. Protons and neutrons are found in the nucleus while electrons are found outside the nucleus of the atom. It is the number of protons of an atom that gives its atomic number. Therefore, an atom with 12 protons has an atomic number of 12.
Therefore, the Correct Answer is B.
