Consider an atom represented by y Xz . That
is, some element X; its atomic number is x , its atomic
weight is y and its atomic charge is z . Answer the following
three questions in terms of x , y , & z , and justify
your answers. How many protons does y Xz have? How
many neutrons does y Xz have? How many electrons
does y Xz have?
Atomic charge = number of protons=Z
Number of neutrons= X-Z
Number of electrons=number of protons=Z
Consider an atom represented by y Xz . That is, some element X; its atomic number...
What is atomic number of an unknown element whose atomic mass and formal charge are (40g/mol) and (-3) respectively? (The unknown element atom has 24 electrons.) Then how many neutrons does the element atom have?
Show the full Nuclear symbol including any + or - charge (n), the atomic number (y), the mass number (x) and the correct element symbol (Z) for each element for which the protons, neutrons and electrons are shown - symbol should appear as follows: *Z,+/-n 31 protons, 39 neutrons, 28 electrons
1. A certain element has 6 protons in its atom. One atom of this element needs _____ electrons in order to have no net charge. 2. Gold has the symbol Au.Located this element on the periodic table above and then identify its atomic number. The atomic number for this element is ____. 3. If you added one more proton to an atom of gold, then what element would it become? A- Silver (Ag) B- Platinum (Pt) C- Mercury (Hg) 4....

-Isotopes are represented by the symbol , where Z is the atomic number, A is the mass number, and E is the elemental symbol. . Write symbol that represents an isotope of nickel that contains 28 protons and 32 neutrons in the nucleus. Isotopes are also represented by the notation: Name-A, where Name is the name of the of the isotope. An example of this isotope notation is magnesium-26. This represents an isotope of The extremely small size of atoms...
