Ring structure is defined as the structure in which one or more series of compounds are joined or linked to form a ring.  Ring can exist in different sizes such as cyclopropane (small ring: three carbon atoms) and cyclohexane (large ring: six carbon atoms).

In ring structure, there is only carbon atoms linked with hydrogen atoms which are identified by the linkage of two lines.

See the attached figure: cyclopropane (unlabelled atoms are carbon atoms with hydogens).

Thus, in ring structure, an unlabelled atom at an angle where two lines joined assumed to be carbon atom.

1. Explain how groups 1A-8A in the periodic table are organized by their number of valence electrons.
nirvana33 [79]

Explanation:

1. Explain how groups 1A-8A in the periodic table are organized by their number of valence electrons.

The valence electrons in an atom are the outermost shell electrons. They are the most loosely held electrons in an atom.

Coincidentally, the periodic table of elements divided into vertical groups and horizontal periods can be said to be arranged according to the number of valence electrons.

  • Atomic numbers are used to arrange elements on the periodic table.
  • Down a group, the number of electronic shell increases. More electrons are added to new energy levels.
  • As we move from left to right across a period, the number of electrons in elements increases but electronic shell is the same.
  • Down a group electronic shell increases but the number of valence electrons are the same.
  • All elements in Group 1A has just one valence electrons, Group 2A has two valence electrons.........Group 8A has eight valence electrons.
  • Moving across groups is synonymous to moving from left to right on the periodic table.
  • Due to this trend, the periodic table is arranged based on the number of valence electrons.

3. explain how you know the number of valence electrons for each group.

The number of valence electrons in a group is the group number:

   Group      Number                     valence electrons

              1A                                                 1

              2A                                                2

              3A                                                 3

              4A                                                 4

               5A                                                5

               6A                                                6

               7A                                                7

               8A                                                8

Use the kinetic energy equation to explain why speed has a greater impact on kinetic energy than mass.​
Lerok [7]

Answer: <em>Hopefully this helps! sorry if not. :))</em>

<em></em>

<em>Speed has a greater impact on mass because its increases in velocity have an exponentially greater impact on translational kinetic energy because kinetic energy is proportional to velocity squared. Doubling an object's mass would only double its kinetic energy, however doubling its momentum would quadruple its velocity.</em>
