MATTER
This is the smallest particle of of an element
What is an atom
These are the horizontal rows on a periodic table ?
What are periods
These are substances that donates hydrogen ions, H+, to form hydronium ions, H3O+, when dissolved in water. Additionally they taste sour and turn blue litmus paper red.
What are acids?
This is needed to change speed into velocity
What is direction?
the center of the atom that contains protons and neutrons
What is the nucleus?
all the known elements in the universe are notated and organized here
What is the Periodic Table of the Elements?
These solutions have a pH of 7?
What are neutral solutions
This is the formula needed to calculate speed or velocity
What is velocity = distance/time
positively charged subatomic particles in the nucleus
What are protons?
formed when atoms of two or more elements combine
What is a molecule?
These substances have a pH higher than 7 and contain Hydroxide (OH) ions? Soap, ammonia, and detergents ae a few examples
What are bases?
This is the tendency of an object to resist a chance in motion and it is Newton's first law
What is the Law of Inertia
melting, boiling, chopping...
examples of physical change
particles in the nucleus that have no charge (neutral)
What are neutrons?
a pure substance composed of two or more elements that are chemically combined
What is a compound?
These factors can increase the rate of solubility
What are heating, stirring, and increasing surface area?
This is a type of force that has a net force of zero
What is balanced forces
burning paper and frying an egg are types of.
These are strong bonds formed between a metal and a nonmetal
What are ionic bonds
This is used to visually interpret different concentrations of soluble substances
What is the solubility curve?
This is a measure of gravitational force exerted on an object. It can change depending on your location even though the object's mass does not.
What is weight
