Solution Steps

Step 1: Understand the Descriptions

First, we need to understand the descriptions provided for each model:

  1. A representation of an atom's valence electrons using dots placed around the chemical symbol of the element: This description refers to a model that visually represents valence electrons, which are the outermost electrons involved in chemical bonding.

  2. The specific arrangement of electrons within the energy levels and orbitals of an atom or molecule: This description refers to a model that details how electrons are distributed across different energy levels and orbitals.

  3. The arrangement of electrons, including their spin, within an atom's orbitals: This description refers to a model that not only shows the distribution of electrons in orbitals but also includes information about their spin.

  4. An atom's electron distribution and electron spin within orbitals along an axis that shows increasing energy: This description refers to a model that visually represents electron distribution and spin, often using a diagram that shows energy levels.

Step 2: Match Descriptions to Models

Now, we match each description to the appropriate model:

  1. Lewis dot symbol: This model uses dots to represent valence electrons around the chemical symbol of an element. It matches the first description.

  2. Electron configuration: This model describes the specific arrangement of electrons in energy levels and orbitals. It matches the second description.

  3. Orbital notation: This model shows the arrangement of electrons in orbitals, including their spin. It matches the third description.

  4. Orbital diagram: This model represents electron distribution and spin within orbitals, often along an axis showing increasing energy. It matches the fourth description.

Final Answer

  • a. Lewis dot symbol: A representation of an atom's valence electrons using dots placed around the chemical symbol of the element.
    \(\boxed{\text{a}}\)

  • b. Electron configuration: The specific arrangement of electrons within the energy levels and orbitals of an atom or molecule.
    \(\boxed{\text{b}}\)

  • c. Orbital notation: The arrangement of electrons, including their spin, within an atom's orbitals.
    \(\boxed{\text{c}}\)

  • d. Orbital diagram: An atom's electron distribution and electron spin within orbitals along an axis that shows increasing energy.
    \(\boxed{\text{d}}\)

DMPLETE SENTENCE has a subject, verb and a complete thought. A RUN-ON SENTENCE is a sentence that has two or more clauses and is joined without a word to connect them or a punctuation mark to separate them. A FRAGMENTED SENTENCE is an incomplete sentence that masks as a sentence; however, the sentence does not make sense. Comma Splice Sentence? A COMMA SPLICE is when two sentences are connected together with only a comma and NO coordinating conjunction like for, and, nor, or, but yet, so. Directions: Defermine if the sentence is a complete sentence, fragment, comma-splice or a run-on sentence. If it is a fragment, comma splice or run-on, rewrite the sentence to make it a complete sentence. 1. Mr. Jones is teaching a lesson on zoology you might find it interesting.
