This is a material that can be broken down chemically into two or more kinds of atoms.
What is a Compound?
100
I am in the first group, 4th period, and my electron configuration is [Ar]4s1.
What is Potassium?
100
This is the number of electrons allowed to live in the P orbital.
What is six?
100
This type of radiation has the lowest frequency.
What are Radio Waves?
100
These two elements are the exception to the Octet Rule.
What are Hydrogen and Helium?
200
These are the three kinds of particles that make up atoms: protons, neutrons, and electrons.
What are Subatomic Particles?
200
I am a Noble Gas, second period, and also a non-metal. I am the continuation in electron configuration for element "Na."
What is Neon?
200
This value will increase within a particular group when there is a higher atomic number.
What is Ionization Energy?
200
This type of radiation is the most dangerous to humans.
What are Gamma Rays?
200
The charge of these metals is +3, since they have 3 valence electrons.
What is Group 13?
300
This is the distance measured from crest to crest of one complete wave.
What is Wavelength?
300
I am in the staircase of Metalloids, I have 5 protons, I'm a part of group 13 and my electron configuration is 1s1-2s2-2p1.
What is Boron?
300
This rule states that it is impossible to determine both the position and momentum of an electron at the same time.
What is the Heisenberg Uncertainty Principle?
300
Frequency is measured in this unit.
What are Hertz?
300
These compounds consist of a metal (positive ion) and a nonmetal (negative ion) and are hard to melt.
What are Ionic Compounds?
400
This occurs when nuclei of lighter atoms combine to form nuclei with greater mass and release a large amount of energy.
What is Fusion?
400
We are metals, we all have positive charges as ions, we have 2 valence electrons, and we make up part of the S block.
What are Alkali Metals?
400
This increases from the top of the Periodic Table to the bottom and from the right to the left.
What is the Atomic Radius?
400
This is a fixed packet of electromagnetic radiation that has a given amount of energy.
What is a Photon?
400
These elements are described as "nonreactive," "inert," and "rare," since they have a full set of valence electrons.
What are Noble Gases?
500
This is a rule that states that atoms tend to gain or lose electrons during chemical reactions so that the atoms have an outer shell configuration of eight electrons.
What is the Octet Rule?
500
I am one of the most common elements known. I have a twin, and my name is very commonly used throughout the science world. You need me to breathe and live.
What is Oxygen?
500
This rule states that electrons will occupy the lowest energy level available before moving to higher levels.
What is the Aufbau Principle?
500
These two particles collide during the photoelectric effect.
