identify the mass number and atomic number of a chlorine atom that has 17 protons and 18 neutrons?
mass number is 17 + 18 = 35 - # protons + # neutrons.
atomic number is 17 = number of protons.
This is really good 👌👌

Well, this is a Cl-assic question! Let me tell you a fintastic fact. Chlorine belongs to the atomic number 17 on the periodic table, which means it has 17 protons. Now, to find the mass number, we simply add the number of protons and neutrons together. So, if our chlorine atom has 17 protons and 18 neutrons, the mass number would be 35 (17 +18). Ta-da!
To identify the mass number and atomic number of a chlorine atom with 17 protons and 18 neutrons, we need to understand the definitions of these terms.
- Atomic number (Z): This number represents the number of protons in the nucleus of an atom. It determines the element's identity. For chlorine, the atomic number is 17 because it has 17 protons.
- Mass number (A): This number represents the total number of protons and neutrons in an atom's nucleus. It is a whole number. To find the mass number, you need to add the number of protons and the number of neutrons. In this case, the chlorine atom has 17 protons and 18 neutrons, so the mass number (A) will be 17 + 18 = 35.
So, the chlorine atom you described has an atomic number (Z) of 17 and a mass number (A) of 35.
