2025 IPC Spring Final Exam Review

The Periodic Table is organized into groups of elements that have similar chemical and physical properties.For example, elements that have properties such as no chemical reactivity and exist as gases at room temperature are part of the (a)   .

• alkali metals

• alkaline earth metals

• halogens

• noble gases

Based on the placement on the Periodic Table, what set of elements have the same number of energy levels?

• Hydrogen, Helium, and Lithium

• Carbon, Nitrogen, and Oxygen

• Titanium, Zirconium, and Hafnium

• Boron, Silicon, and Arsenic

As electrons fall from high energy orbitals to lower orbitals, energy is released in the form of electromagnetic radiation. The farther the electron falls, the more energy is released. Which of the following electronic transitions would produce a wave with the lowest frequency?

• an electron falling from the 6th to the 2nd energy level

• an electron falling from the 3rd to the 2nd energy level

• an electron falling from the 5th to the 2nd energy level

• an electron jumping from the 1st to the 2nd energy level

FEQ

What is an electron transition?

• as electrons transition to other subatomic particles, such as protons and neutrons

• as electrons gain and lose energy and move between orbitals

• as electrons increase their kinetic speed within their orbital

• as electrons gain or lose negative charge

FEQ

Copper is used in wiring and cookware because it can conduct electricity and heat well. What property of copper allows it to do this?

• electrons move freely around the copper ions

• protons are not tightly bonded in the nucleus to the neutrons

• copper always has a negative charge giving it less electrons to slow down movement

• metals are high energy levels so it cannot hold onto heat or electricity
