ELECTRONS & WAVES
This electromagnetic spectrum wavelength is the shortest wavelength.
What are gamma rays?
This form of radiation has the longest wavelength.
What are radio waves?
These electrons determine how reactive an atom is.
What are valence electrons?
This model shows electrons in specific energy levels.
What is the Bohr model?
These are the four types of orbitals.
What are s, p, d, and f?
This element has the electron configuration ending in 3p⁵.
What is chlorine?
This type of radiation includes radio waves, visible light, and X-rays.
What is electromagnetic radiation?
This form of radiation is visible to the human eye.
What is visible light?
Atoms become stable when they have this many valence electrons.
What is 8 (the octet rule)?
This model explains electron behavior using orbitals and probability.
What is the quantum model?
This orbital holds a maximum of 2 electrons.
What is the s orbital?
This element’s noble gas configuration is [Ar]4s².
What is calcium?
This term describes the distance between two wave peaks.
What is wavelength?
As energy increases on the electromagnetic spectrum, wavelength does this.
What decreases?
An atom that loses electrons becomes this type of ion
What is a cation?
The first energy level can hold this many electrons.
What is 2?
This orbital begins filling in the fourth period.
What is the d orbital?
This element is the first to fill the 3d orbitals.
What is scandium?
This property of a wave increases as wavelength decreases.
What is frequency?
X-rays have more energy than this type of radiation.
What is visible light?
An atom that gains electrons becomes this type of ion.
What is an anion?
The second energy level can hold this many electrons.
What is 8?
This rule explains why electrons fill the lowest energy orbitals first.
What is the Aufbau principle?
This element has 53 electrons and ends in 5p⁵.
What is iodine?
This scientist’s principle states you cannot know both an electron’s position and momentum exactly.
What is the Heisenberg uncertainty principle?
Energy, frequency, and wavelength are all related in this way.
What is that as frequency increases, energy increases and wavelength decreases?
This diagram shows only valence electrons using dots around an element symbol.
What is a Lewis structure?
This explains why electron configurations get more complex in the fourth period.
What is the addition of the d orbitals?
This shorthand electron configuration uses the nearest noble gas.
What is noble gas notation?
This transition metal has a partially filled d orbital and atomic number 28.
What is nickel?
