The number of protons in an atom equals the number of ___.The atomic mass is equal to: A. the number of neutrons. B. the number of protons plus the number of electrons. C. the number of protons plus the number of neutrons. D. the number of electrons. E. the number of protons...
by definition, the molar mass of so 3 equals its molecular mass in grams. so the calculation of the molecular mass of so 3 is required first. solution: the molecular mass (or formula mass) of a compound is the sum of the atomic masses of all the atoms in the molecule. the molecular...
5. What does the atomic number tell you? 6. Define the term isotope. Average Atomic Mass: Notice how the atomic masses are NOT whole numbers. (For example the atomic mass of sodium is 22.99 NOT 23). These are the average atomic masses for elements. This is a weighted average so more ...
The quantity of protons equals the quantity of electrons, so everything’s set, right? Well, no! The number of neutrons in all the elements can vary. For instance, stable helium atoms can (and do) have 1, 2, or even 3 neutrons in its nucleus. Carbon atoms contain 6, 7, or 8 neu...
In a neutral atom, the number of protons equals the number of electrons. 4 Electrons Negatively charged particles that orbit an atom's nucleus. Electrons move around the nucleus in specific shells. 7 Proton The primary contributor to an element's atomic number. Carbon, with six protons, has ...
