Con Chem Periodic Table Scavenger Hunt

Directions: Using your chromebook, navigate to the website www.ptable.com. You will interact with this periodic table to find the answers the questions below.
1

What color element symbol designates elements that are a gas at a given temperature?

1

What color element symbol designates elements that are a liquid at a given temperature?

1

What color element symbol designates elements that are a solid at a given temperature?

1

What family of elements does the purple color indicate?

7

Click on the Ptable symbol in the upper left corner to reset the table. Find the Metalloid elements. What are their symbols?

1

How many liquid elements exist?

1

List the symbol of a liquid element.

Remaining in the properties tab, locate the property of radius. The radius is one way to represent the size of an atom. As electrons are added to any given energy level, they are pulled closer to the nucleus. This is due to an increase in nuclear strength as protons are added to the nucleus. As additional energy levels are filled with electrons, the nuclear strength decreases. Use the trend of radius to answer the following questions.
1

What is the atomic radius of Li in pm?

1

What is the atomic sodium of sodium in pm?

1

What is the atomic radius of potassium in pm?

1

Observe the values for atomic radius for the alkali metals in Group 1. How do they compare to one another?

1

What is the atomic radius of beryllium in pm?

1

What is the atomic radius of carbon in pm?

1

What is the atomic radius of fluorine in pm?

1

Observe the radius for all elements in the second period (row) of the periodic table. What do you observe?

Ionization energy is the energy required to remove an electron from a neutral atom. Some atoms will give up electrons easier than others. Those atoms have lower ionization energies because less energy is required to remove the electron. As a result, elements with low first ionization energies will easily form positively charged ions.
1

What is the ionization energy of magnesium in kJ/mol?

1

What is the ionization energy of calcium in kJ/mol?

1

What is the ionization energy of strontium in kJ/mol?

1

Staying in the "Properties" tab, observe the 1st ionization energy for elements in the alkaline earth metal group. What observation can be made about the ionization energy going down a group?

Now observe ionization energies across the elements in period (row) 3.
1

What is the ionization energy of sodium in kJ/mol?

1

What is the ionization energy of aluminum in kJ/mol?

1

What is the ionization energy of chlorine in kJ/mol?

1

What general observations can be made about the ionization energies across a period?

Electronegativity is another property that can be observed for most elements. Electronegativity measures the attraction an atom has for electrons. Elements with large electronegativies will have a very strong attraction for electrons, whereas elements with low electronegativity values will have a weaker attraction for electrons.
1

What is the electronegativity of lithium?

1

What is the electronegativity of beryllium?

1

What is the electronegativity of nitrogen?

1

What is the electronegativity of fluorine?

1

What general statement can be made about the electronegativity of elements across a period on the periodic table?

1

What is the electronegativity of chlorine?

1

What is the electronegativity of bromine?

1

What is the electronegativity of iodine?

1

What general statement can be made about the electronegativity of elements down a group on the periodic table?

1
