Which isotope has 18 protons and 22 neutrons? 3
18 protons identify the element, element number 18 (elements are counted according to the number of protons). If you look at the element 18 in Table ic, you will see that it is an ■■■■■ (symbol Ar).
We now name isotopes by the name of the element and the number of particles (protons and neutrons) in the nucleus. In this case, we have 18 protons and 22 neutrons, so the number of particles is 18 + 22 = 40.
So our isotope is called Ar40. (In fact, it's the most abundant ■■■■■ isotope on Earth, making up over 99% of the ■■■■■ atom.) I see that helps!
The number of protons in an element varies ... so 18 indicates that the element must be an isotope of Ar. m 18 + 22 = 40 is not. Its isotope is Ar40.
Because isotopes only change neutrons. The number of protons is important. Which element has 18 protons? ■■■■■
Since only neutrons fit in an isotope, the number of protons is equal to the atomic number.
Therefore, element atomic number 18 is Argan.
