Junk Drawer
The name for mixtures like salads, trail mix, oil and water, etc.
What is heterogeneous?
The term we use for average kinetic energy
What is temperature?
The subatomic particle that determines the identity of the atom
What is a proton?
The type of decay resulting from losing a helium nucleus
What is alpha decay?
What are the Noble Gases?
3 is the number of them for this quantity: 0.00500
What are significant figures?
Heat tends to move from an area of greater molecular movement to slower molecular movement until it reaches this state.
What is equilibrium?
The subatomic particle that determines the reactivity of an atom.
What is an electron?
This type of decay would allow the element to remain the same while releasing a large amount of energy.
What is gamma decay?
This group on the periodic table has 7 valence electrons and is extremely reactive.
What are the halogens?
The color yellow on the NFPA safety diamond.
What is the reactivity section?
The law we use to quantify the relationship between volume and temperature.
What is Charles Law?
The term used to describe an atom that has more electrons than protons.
What is an anion?
The process of using isotopes to determine the age of different objects.
What is radioisotope or carbon dating?
This group on the periodic table are semi-conductive, sometimes brittle/malleable, and have varying properties.
What are metaloids?
The third planet from the sun.
What is Earth?
The law we use to quantify the relationship between number of moles and volume.
What is avogadro's law?
The term used to differentiate between the same element with different masses.
What is an isotope?
The type of decay that emits an electron and changes a neutron in the parent isotope to a proton.
How the periodic table is organized
What are periods and groups based on trends and properties (like the alien periodic table)
The term for a mathematical relationship where when one quantity increases the other decreases (and vice versa).
What is inverse?
Gas molecules tend to have these types of collisions, meaning that when they hit each other they bounce off completely conserving energy.
What is elastic?
How you determine the number of neutrons in an atom.
What is taking the mass and subtracting the atomic number?
This quality increases as frequency increases.
What is energy?
The leading architect behind the modern periodic table we use today.
Who is Mendeleev?
