name each isotope, and write it in symbolic notation
atomic number 26; mass number 56
atomic number 29; mass number 64
atomic number 17; mass number 37
The atomic number is the number of protons and "names" the element. You write the element, as in X, then to the lower left a subscript with the atomic number and to the upper left a superscript that shows the mass number.
thanks for the help but i don't understand what its supposed to look like. can u show me an example please
ok i just looked it up. so for the first one would it look like this
56
26 Fe
atomic number 26; mass number 56
I think you have it.
The atomic number is 26, that tell you the number of protons. The periodic table tell you the element is Fe. 56 is the mass number. It is written this way.
2656Fe
To name each isotope and write it in symbolic notation, we need to understand the notation itself. Isotopes are atoms that have the same atomic number but different mass numbers. The atomic number represents the number of protons in the nucleus of an atom, while the mass number represents the sum of protons and neutrons.
Let's name and write each isotope in symbolic notation based on the given information:
1. Atomic number 26; mass number 56:
The atomic number of 26 indicates that the element is iron (Fe) since iron has 26 protons. The mass number 56 represents the sum of protons (26) and neutrons. To write the symbol for this isotope, we combine the element symbol "Fe" with the mass number as a superscript before the symbol: Fe-56.
2. Atomic number 29; mass number 64:
The atomic number of 29 corresponds to the element copper (Cu) since copper has 29 protons. The mass number 64 represents the sum of protons (29) and neutrons. Therefore, the symbolic notation for this isotope is Cu-64.
3. Atomic number 17; mass number 37:
The atomic number of 17 indicates the element chlorine (Cl) since chlorine has 17 protons. The mass number 37 represents the sum of protons (17) and neutrons. Thus, the symbolic notation for this isotope is Cl-37.
In summary:
Isotope 1: Iron-56 (Fe-56)
Isotope 2: Copper-64 (Cu-64)
Isotope 3: Chlorine-37 (Cl-37)
