Atoms
These three things make up the basic parts of an atom.
What are protons, electrons and neutrons?
These compounds produce hydrogen ions (positive charge) in aqueous solutions
What is an acid?
This substance is made up of two hydrogens and two oxygens (H2O2)
This column of metals are shiny, can be cut with a knife, and happen to make up the first column on the periodic table.
What is the alkali metals?
This element's explosive property is responsible for the Hindenburg disaster.
What is hydrogen?
This tiny part of an atom has a negative charge.
These compounds produce hydroxide (negative charge) ions in aqueous solutions.
What are bases?
This type of reaction releases either heat or light.
What is an exothermic reaction?
This is the largest group of elements on the periodic table. They have very high melting points.
What are the transition elements?
If you add electricity to this usually colorless element, very bright colors appear
What is neon?
The middle of the atom made up of protons and neutrons is called this.
What is a nucleus?
This scale is used to measure how acidic or basic something is
What is the pH scale?
This type of gas was released when we added yeast to hydrogen peroxide.
Oxygen gas
These gases don't want to react with any other elements. Perhaps that is why they are called this.
What are the noble gases?
What is lead?
This element is the only element that might not have a neutron
What is hydrogen?
On the pH scale, a neutral substance has this value.
What is 7?
This substance is left over at oxygen gas is released from hydrogen peroxide after a catalyst is added.
What is H2O?
What are the halogens?
Chlorophyll has a lot of this element in it.
What is magnesium?
The atomic number is determined by the number of these in an atom of an element.
What are protons?
Substances act as this when they measure the pH of a solution. (Litmus paper or cabbage leaf juice are examples of this)
What is a pH indicator?
A material that increases the rate of reaction without itself being consumed (Yeast acted as this during our elephant toothpaste experiment)
These two groups of metals are forced to the bottom of the periodic table to allow the table not to be super stretched out.
What are the lanthanides and actinides?
This element turns starches blue and also is needed by our thyroid gland to allow it to function properly.
