  1. Which property measures an atom's ability to attract electrons in a bond?

    Answer: Electronegativity

    Electronegativity is the measure of an atom's tendency to attract bonding electrons toward itself.

  2. How many electrons can the d subshell hold?

    Answer: 10

    The d subshell contains 5 orbitals, each holding 2 electrons, for a maximum of 10 electrons.

  3. What happens to an atom when it loses an electron?

    Answer: It becomes a positive ion (cation)

    Losing an electron leaves the atom with more protons than electrons, giving it a net positive charge (cation).

  4. Which type of bond is found in metals and involves a 'sea of electrons'?

    Answer: Metallic bond

    Metallic bonding involves delocalized electrons that move freely among positively charged metal ions.

  5. In which region of the atom are protons and neutrons located?

    Answer: Nucleus

    Protons and neutrons are densely packed in the nucleus at the center of the atom.

  6. A Lewis dot structure primarily represents which part of an atom?

    Answer: Valence electrons

    Lewis dot structures show valence (outermost shell) electrons because those are involved in bonding.

  7. Two atoms sharing three pairs of electrons form a:

    Answer: Triple bond

    Three shared electron pairs constitute a triple bond, as seen in molecules like N₂.
