My Electrons

I have 7 electrons. The first 2 electrons occupy the first electron shell. The remaining 5 electrons fill the second electron shell. The second shell can hold 8 electrons, which means that I want to gain 3 more electrons to create a full outer shell. Since I gain 3 electrons, I have 3 valence electrons and have 3 covalent bonds.

My Properties

I am a non-metal that is colorless, odorless and tasteless. I am an inert diatomic gas.

  • Density:1.2506g/L
  • Boiling Point: 77.5K (Kelvin)
  • Conductivity (thermal): 0.0002598 W/cmK
  • State @ room temperature: gas

  • Liquid Nitrogen

    My Home (Body, Planet, Universe)

    The human body is 3% Nitrogen. I can be found in proteins and amino acids.
    Nitrogen composes approximately 75.5% (by weight) of the Earth's atomosphere.
    I am the fifth most abundant chemical in the universe. There are several solar type stars that show an abundance of nitrogen.

    My story

    Daniel Rutherford
    I was discoverd by Daniel Rutherford in 1772 in Scotland. He first called me 'noxious air.' In the 18th century, people believed that there were two types of gases in the air, one that supported life and one that did not. Oxygen was the gas that supported live, and supposedly, nitrogen was the gas that did not. This was later proven wrong because Nitrogen is a nutrient that plants use.

    My Job

    I am used in many different ways and have many jobs.
    I am used to make explosives, ammonia, fertilizer and light bulbs.
    I am also used to preserve packed foods,and to prevent fire hazard in military aircraft fuel.
    I am used in the production of stainless steel.

    Liquid Nitrogen can be used to make ice cream, as shown in this video.

    How to make liquid nitrogen ice cream (from

    • 4 cups whole organic milk
    • 1 vanilla bean, split
    • 1 cup of sugar
    • 3 tablespoons plus 2 teaspoons of cornstarch
    • 1 teasopoon vanilla extract
    "Place three cups of the milk in a saucepan with the vanilla bean over medium-low heat.
    Meanwhile, pour the remaining 1 cup milk into a large glass measuring cup. Add the sugar and the cornstarch. Mix well.
    When the milk starts to simmer, remove it from the heat and pour in the cornstarch mixture, stirring the whole time. Return the saucepan to medium-low and stir, stir, stir, until things start thickening up, 10 to 12 minutes. It should end up thicker than, say, a runny milkshake, but thinner than a frosty one.
    Pour the mixture through a strainer into a mixing bowl, whisk in the vanilla extract, and let it cool on the counter for 20 minutes or so. I like to then chill it in the refrigerator for a few hours or overnight until it is completely chilled."
    Pour mixture into metal bowl then add liquid nitrogen. Do not put too much or else the mixture will harden because liquid nitrogen freeze things quickly. Put as much needed to freeze mixture.
    Serves 6.
    Be careful because liquid nitrogen is really cold.
