Each chemical symbol is for a chemical element; each chemical element has a specific atomic number and an atomic weight (not mass, after the rule of IUPAC).

Which isotopic notation identifies a metalloid that is matched with the corresponding number of protons in each of its atoms?
28^Si and 14 protonsThe metalloid Si (silicon) is correctly matched with 14 protons, because the atomic number of Si is 14.
Elements in atomic bomb?
Atomic bombs contain uranium (highly enriched in the isotope 235U) or plutonium (a very specific isotopic composition).
Write the nuclide symbol for carbon-13?
Here is the isotopic notation for carbon 14. From looking at the isotopic notation, you can find the number of protons, neutrons and electrons in an atom. Protons- The atomic number is 6, so there are 6 protons Electrons- If the atom is neutral the number of protons equals the number of electrons, so there are also 6 electrons Neutrons- The mass number equals the number of protons + neutrons, and 14-6 leaves 8 neutrons 14 C 6

What relationship exist between the atomic mass and the isotopes?
When atomic mass is expressed in unified atomic mass units, it is similar to isotopic mass and has the same numerical value as that of atomic mass. The atomic mass or the relative isotopic mass is the mass of one atom which at a time can be only one isotope.
How is average weight of atomic mass computed?
the average atomic mass is computed by summing all isotopic weights of the isotopes of that element and then dividing this by the the total number of isotopes of that element (note that isotopic mass is exactly the same as atomic weight, except for isotopes).
How do you calculate isotopic masses?
The atomic mass of isotopes is determined by mass spectrometry.
What is the average atomic mass of the element with the isotopic abundances shown?
90.7 amu
Which isotopic notation identifies a metalloid that is matched with the corresponding number of protons in each of its atoms?
28^Si and 14 protonsThe metalloid Si (silicon) is correctly matched with 14 protons, because the atomic number of Si is 14.
What is need to determine atomic mass of chlorine?
For the determination of the atomic weight (not mass) of chlorine we need to know the isotopic composition of Cl and the atomic masses of the isotopes.
How you determined the relative atomic mass of oxygen?
The atomic weight (not mass) of any element is determined taking into account the isotopic composition and the atomic masses of these isotopes.
How do you find the atomic notation for an atom?
the atomic notation is 7 x 4940 equals folowing
Elements in atomic bomb?
Atomic bombs contain uranium (highly enriched in the isotope 235U) or plutonium (a very specific isotopic composition).
What is the fraction in calculating the average atomic weight of an element?
The atomic weight (not mass) of a chemical element is calculated considering the isotopic composition of the element and the atomic masses (not weights) of these isotopes.
What is the isotopic notations for neon?
The chemical symbol is Ne. An isotope is writted as: 2010Ne (20 is the atomic mass of the isotope, 10 is the atomic number of Ne).
What are the isotopic symbols?
Isotopic symbols are used to represent elements and isotopes. They consist of the element's symbol, atomic number (number of protons), and mass number (sum of protons and neutrons). For example, carbon-12 is represented as ^12_6C, where 6 is the atomic number and 12 is the mass number.
