In practical terms, this means that an orbital can hold a maximum of two electrons, and they must have opposite spins.<\/li>\n\n\n\n<li><strong>Heisenberg Uncertainty Principle<\/strong>: It\u2019s impossible to simultaneously know both the position and momentum of a particle precisely.<\/li>\n<\/ul>\n\n\n\n<p>Based on the given configuration and question, we\u2019re likely looking at a situation where an orbital might have more than two electrons with the same spin, violating the <strong>Pauli Exclusion Principle<\/strong>.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Correct Answer:<\/h4>\n\n\n\n<p><strong>c.
