Metals Nonmetals and Metalloids
These are the names of the three main groups of elements.
What are metals, non metals and metalloids?
This is the subatomic particle with a negative charge.
What is an electron?
This is a specific type of atom with unique properties.
What is element?
A formation of a precipitate is the result of this type of reaction.
What is a chemical reaction?
This is the scientist who designed the PH scale.
Who is S P L Sorenson?
Has a sour taste and corrodes metal.
What is an acid?
These are lightweight elements that are very reactive.
What are Alkali Metals?
These are found between the metals and non metals.
What are metalloids?
This is the subatomic particle with a neutral charge. ( you must give the equation for how to find the number of these.)
What is a neutron? And the atomic mass minus the atomic number.
This is the formula for finding density.
What is mass over volume?
The atoms completely rearrange during this.
What is a chemical change?
This scientist arranged the known elements based on how they react with the ones around them.
Who is Demetri Mendeleev?
Bases are made of these types of ions.
What are hydroxide ions?
These elements are at the bottom row of the inner transition metals
What are Actinides?
This metal is the only metal that is found as a liquid at room temperature.
What is Mercury?
This is the subatomic particle that is the same as the atomic number.
What is a proton?
This is the difference between a compound and a molecule.
What is all compounds are molecules but not all molecules are compounds?
A change in solubility is the result of this.
What is a a physical change?
This scientist created the atomic theory.
Who is John Dalton?
Acids are made of these type of ions.
What are Hydrogen ions?
What are the top row elements on the inner transition metals called?
What are Lanthanides?
These are an example of one element from the metals, one from the non metals, and one from the metalloids.
Answers will vary.
This is the empty space surrounding the nucleus.
What is the electron cloud?
This is what we call this and how we know it is a compound.
NaCl + HO + N
What is a chemical formula?
This is what we call it when an object can be easily formed into another shape.
What is malleable?
This is the "Father of Modern Chemistry"
Who is Robert Boyle?
These types of compounds have a positive charge while these have a negative charge.
What are acids and bases?
This element does not have any neutrons.
What is Hydrogen?
These are the properties of metalloids.
What are metal and nonmetal properties?
This is what Aristotle believed all things were made of.
What is earth, water, fire and air?
This is how many elements are on the periodic table, the number found naturally and the number of elements that are synthetic.
What is 118, 92 and 26
This is what we call it when an object can be stretched into a long string.
What is ductile?
This the scientist who invented dynamite and now we give awards and money to people who do good works in science and/or for society as a whole.
Who is Alfred Nobel?
When you mix an acid and a base you get this.
What is water and salt.
This is the number found on the Element Square that shows which shells the electrons go on.
What is the electron configuration?
