- What is the maximum number of electrons that each p orbital can hold?
- What is the maximum number of electrons that the second energy level can hold?
- What is the name of the individual who proposed that the atom was similar to a solar system, with a dense nucleus and concentric circles around it?
- The horizontal rows of the periodic table are called
- representative elements.
- Which of the following is an alkali metal (group IA)?
- Who stated that an orbital can hold as many as two electrons if they have opposite spins, one clockwise and one counterclockwise?
- Which elements conduct electricity?
- If the electron configuration of an element is written: 1s2 2s2 2p6 3s2 3p3, the element's atomic
- number is 15.
- number is 5.
- weight is 15.
- weight is 5.
- a. Since there are 11 electrons in the element's electron configuration, the element has 11 protons and, therefore, an atomic number of 11.
- d. See the periodic table.
- b. Each p orbital holds two electrons. There are three p orbitals, holding a total of six electrons.
- a. The second energy level has one s orbital and three p orbitals, holding a total of eight electrons.
- d. Bohr proposed the model defined in the question.
- d. By definition, the periods are the horizontal rows on the periodic table.
- b. Sodium is an alkali metal.
- c. The question defines Pauli's exclusion principle.
- a. Metals, by definition, conduct electricity.
- a. Since the element has 15 electrons, it also has 15 protons and an atomic number of 15.
