Chemistry. Period!
What is Periodicity?
Periodicity refers to the repeating pattern of properties of elements in the periodic table.
What are alkaline earth metals?
These metals are highly reactive and tend to form 2+ cations with non-metals.
What is the element in Group 17 is commonly used to disinfect water?
Chlorine
What is the chemical formula for dinitrogen pentoxide?
N2O5
Duck feathers are said to be this, allowing them to swim under water briefly.
Hydrophobic
What is ionization energy?
Ionization energy is the energy required to remove an electron from a neutral atom in its gaseous state.
What is the element with the highest melting point in Group 2?
Beryllium
What is the most reactive Halogen?
Fluorine
Why does Nitrogen gas in the atmosphere tend to be inert?
Due to its strong triple bond
Duck eggs are generally white. However, some eggs can be this color.
Pale green
What is the trend of atomic radius within a period?
The atomic radius generally decreases from left to right within a period on the periodic table.
What is the element with the lowest electronegativity in Group 2?
Barium
What is the common oxidation state of halogens in compounds?
-1

What would be the pH of the solution formed when dissolving Sodium oxide in water
Very Basic around 14 pH
Which 3 group 2 metals are most reactive with water?
Calcium, Strontium, Barium
What is an indication of iodide ions present after the addition of silver nitrate?
Yellow precipitate
ammonium nitrate is considered a good fertilizer. Why would this be true?
Hint: Consider what the molecular formula is and how it would separate into ions.
It can dissociate to form NH3 and HNO3. Two sources of nitrogen. Nitrogen is good for plants helping form amino acids.
Who was the first on screen duck debuting in 1934?

Barium oxide
Which precipitate will dissolved readily in dilute aqueous ammonia?
Chloride precipitate
Ammonium ions are said to contain a dative or coordinate bond. What is meant by this type of bond.
Hint: Consider the structure of ammonia and the ammonium ion
A bond formed from one atom providing both electrons needed to create the bond.
