Boiling water is this type of change
What is a Physical change
The outfit that you are wearing can be considered this category of matter when you put it all together
(be specific)
What is a heterogeneous mixture
This is a compound made of 2 nonmetals
What is a covalent compound
This is what we refer to as the property that allows metallic bonds to have many of their properties such as the ability to conduct electricity in a solid state
What is the sea of electrons
These are the 5 indicators of a chemical reaction
Color Change
Temperature change
Odor produced
Bubbles or gas produced
Precipitate formed
This type of wave has the longest wavelength of all of the electromagnetic waves
What are radio waves
These are the particles in the outermost orbital of an atom
This type of compound has very strong bonds and therefore high melting points
What are ionic bonds
An atom that is only found in its pure state when it is paired with another atom of the same type is called this
What is a diatomic element
This atomic scientist discovered the negatively charged subatomic particle
Who is JJ Thompson
This is an atom that has a different number of neutrons than another atom of the same element
What is an Isotope
This is the factor that increases reactivity in metals as you move to the left on the periodic table
What is a fewer number of valence electrons
This is the name of the compound with the formula C3P5
What is tricarbon pentaphosphide
These are the electrons on an atom that do not bond to another element
What are the lone pair electrons
These two properties of waves have an inverse relationship
wavelength and frequency
This type of radiation has the least energy and the most mass
What is alpha radiation
This family is considered the most reactive nonmetals
What are halogens
This is the formula for Chromium (II) Nitrate
What is Cr(NO3)2
This is the reason that covalent bonds are found as gases at room temperature
What is the weak intermolecular forces between bonds
This is the noble gas configuration of Phosphorus
What is [Ne] 3s2 3p3
This is why atomic radius increases as you move down on the periodic table
What are the increased number of electron orbitals
These are the 4 blocks of the periodic table that you would use for electron configuration
What are s,p,d,f
This is the VSEPR shape that a compound with 4 total atoms and 1 lone pair would have
What is trigonal pyramidal
This is the one reaction that is not considered a redox reaction
In the following reaction what are the coefficients in front of all compounds present.
sodium phosphate + potassium chloride → potassium phosphate + sodium chloride
