1. Electrons orbit the nucleus in discrete shells or energy levels. 2. Protons and neutrons reside in the nucleus, with protons being positively charged and neutrons having no charge. 3. The number of protons (atomic number) defines the element, and atoms are electrically neutral when the number of electrons equals the number of protons.

FAQs & Answers

  1. What defines an element in atomic structure? An element is defined by its number of protons, known as the atomic number.
  2. Why are electrons important in atomic structure? Electrons determine the atom's charge and are crucial in chemical bonding.
  3. What are the energy levels in atomic structure? Energy levels are the specific orbits where electrons reside around the nucleus.
  4. How do protons and neutrons differ in atomic structure? Protons are positively charged particles found in the nucleus, while neutrons have no charge.
