Ответ:
I`m pretty sure that B is right
Explanation:
Ответ:
I believe its B or D
B
The atomic number is equal to the number of protons in an atom’s nucleus. The atomic mass is the sum of the mass of protons and neutrons. Protons and neutrons have approximately the same mass, about 1.67 × 10 -24 grams, which scientists define as one atomic mass unit (AMU).
D
Atoms from two different elements may have the same number of neutrons, but never the same number of protons. The number of protons is unique to the element and represents the atomic number. For example, you can look at radioactive decay.
