HODGE-PODGE
100
Properties like size, shape, state of matter (gas, liquid, solid), color.
What are QUALITATIVE PROPERTIES of MATTER?
100
The rows on the periodic table
What are PERIODS?
100
0° Celsius
What is the freezing point of water?
100
This group of elements does not react with other elements.
What are the Noble Gases?
100
This number is neutral on the pH scale.
What is 7?
200
Measurement or number (numerical) descriptions
What are QUANTITATIVE PROPERTIES of MATTER?
200
The columns on the periodic table.
What are GROUPS?
200
These orbit around the nucleus of an atom.
What are electrons?
200
Cola, vinegar, and orange juice are examples of this.
What is an acid?
200
The scientific study of the negative effects in living things due to chemicals is called this.
What is toxicology?
300
This state of matter has a fixed shape and volume. It's atoms are tightly packed together
What is a solid?
300
Name two of the three main groups on the periodic table.
What are metals, non-metals, or metalloids?
300
The neutrons and protons are found in this part of the atom.
What is the nucleus?
300
Burning wood is an example of this type of reaction.
What is exothermic (gives heat out)?
300
Give an example of a physical property.
What is mass, volume, length, shape, color, melting point, boiling point, density
400
This state is malleable (it can change shape). It has a constant volume. The atoms are close together, but can move to form the shape of a container.
What is a liquid?
400
This change in an atom makes every element on the periodic table different. When this is changed, a new element is formed.
What is the number of protons or the atomic number?
400
Two or more atoms of the same element, or different elements, that are chemically combined
What is a molecule?
400
This group on the periodic table has 6 valence electrons. (ask to see a periodic table, if you need it)
What is Group 16?
400
Name 3 principles of green chemistry.
What is prevent waste, maximize materials, lower toxicity (poison level), make safer chemicals, no solvents, use less energy, use renewables, use catalysis, design it so it can decompose safely into the environment once it is finished, think about and make changes to the process, accident prevention?
500
Rusting metal on a car, is an example of this...
What is a chemical change?
500
Each element in a group on the periodic table react the same way chemically because they have this in common.
What is the same number of valence electrons?
500
Atoms of two or more different elements that are bound together. They can broken apart only by chemical means, not physical means.
What are compounds? Note that mixtures are two or more different elements that are physically together. They can be separated or taken apart by physical means
500
The use of salt (NaCl) on roads in the winter helps to melt the ice because of this.
What is freezing point depression?
500
Give an example of a chemical property?
What is something that can react with air, acid, base, water, other chemicals and it changes the identity of the substance?
