Problem 42E

Which statements are inconsistent with Rutherford’s nuclear theory as it was originally stated? Why?

a. Since electrons are smaller than protons, and since a hydrogen atom contains only 1 proton and 1 electron, it must follow that the volume of a hydrogen atom is mostly due to the proton.

b. A nitrogen atom has 7 protons in its nucleus and 7 electrons outside of its nucleus.

c. A phosphorus atom has 15 protons in its nucleus and 150 electrons outside of its nucleus.

d. The majority of the mass of a fluorine atom is due to its 9 electrons.

Step-by-Step Solution:
Step 1 of 3

Solution 42E Here, we have to write the chemical name for the symbol along with its position in the periodic table and atomic number and indicate if it is a metal, metalloid or a non-metal. I n general, within a ow ( eriod) the el ments placed on the l eft are metals and elements placed on the r ight are nonmetals and it also contains noble gases. Metalloids are chemical elements that have properties both metals and nonmetals. Metalloids are the elements found along the stair-step line that distinguishes metals from nonmetals. The position of the elements Li, Sc, Ge, Yb, Mn, Sb and Xe in the periodic table as : (a) Li : Lithium is the chemical name of the symbol Li. It has an atomic number of 3. It belongs to group 1A (alkali metals), locates in the extreme left of the periodic table and it is a metal. (b) Sc : Sc is the chemical symbol of the element scandium. It has atomic number 21. It belongs to group 3B, a transition metal category, and it is a metal. (c) Ge : Germanium is the chemical name of the symbol Ge and it has an atomic number of 32. It belongs to group 4A and is a metalloid. (d) Yb : Yb is the chemical symbol of the element ytterbium having atomic number 70. It belongsto transition metal category, It is the fourteenth and penultimate element(last but one element) in the l anthanide series(it comprises the fifteen m etallic chemical elements with atomic numbers 57 through 71, from l anthanum through l utetium. They are also called rare-earth elements) and it is a metal. (e) Mn : Manganese is the chemical name of chemical symbol Mn and has an atomic number of 25. It belongs to 7B group( transition metal category), and it is a metal . (f) Sb : Antimony is the chemical name of symbol Sb. It has an atomic number 51. It belongs to group 5A and it is a metalloid. (g) Xe : Xenon is the chemical symbol of symbol Xe and it has an atomic number 54. It belongs to group 8A (noble gases) and it is a nonmetal.
