Helium[image]

It's so funny! Breathing in helium and talking. You sound like you're from another planet. So how does it work?
Helium is less dense than the air you normally breathe. The lighter the air, the faster sound waves can travel through it. Makes sense. So you don't change your actual voice, you change the speed at which the sound waves leave you. This makes it SOUND higher pitched. By inhaling helium you are effectively increasing the speed of the sound of your voice. Your vocal chords are not altered at all. As far as being dangerous, it's not dangerous to breathe it from a balloon because you will take in some oxygen too AND it isn't under much pressure. But avoid breathing it from a tank. The pressure can cause helium bubbles to enter your blood stream through your lungs.

Carbon

[image]

Carbon is a solid, non-metal.
 Carbon’s atomic number is 6
 It’s in the 14th column of the periodic table so that means its outer shell has 4 electrons.
 Carbon has been known since ancient times. It is named after the Latin word for coal, Carbo.
 Carbon is the most abundant (in the largest amount) element in the bodies of living things.
 Carbon exists in 3 forms, diamond, coal and buckyballs.
 Diamond is the hardest substance on earth.
 Carbon bonded to itself to make diamond, has a unique crystalline shape.
 Carbon bonded to itself in layers makes coal.
 Carbon bonded to itself in a round ball shape is called a Buckminsterfullerene or Buckyball. It looks like a soccer ball.
 Buckyballs are used as microscopic ball bearings and are perfect lubricants.
 Because carbon can bond to itself and can form chains of carbon, it is the only element that is complex enough to support life.
 Carbon has its own branch of chemistry called organic chemistry.
 Carbon as an element, is recycled from the atmosphere to living things and back to our atmosphere.
 Carbon in our bodies is released bonded to oxygen as carbon dioxide.
 Dry ice is made from liquid carbon and oxygen (carbon dioxide). It is released so quickly that it reaches temperatures so low it freezes. Frozen carbon dioxide does not melt, it skips the liquid stage and returns to a gas. This process is called sublimation.
 Isotopes of carbon have many uses in chemistry. Carbon has 3 isotopes.

Sodium Na

Sodium is a bright, silvery metal. It is soft and highly reactive. Sodium floats on water. Sodium may ignite spontaneously on water. It does not usually ignite in air at temperatures below 115°C.  (room temperature is 20-25 degrees celsius)

[image]

Silicon ( Si ) Semimetallic

The melting point of silicon is 1410°C.

Silicon makes up 25.7% of the earth's crust, by weight, making it the second most abundant element (exceeded by oxygen).

Chlorine (Cl ) Halogen

[image]

Element Classification: Halogen

Atomic Weight: 35.4527

Sources: In nature, chlorine is only found in the combined state, most commonly with sodium as NaCl

Appearance: greenish-yellow, irritating gas

Chlorine has a melting point of -100.98°C

What is this molecule?

[image]

Ethane C₂H₆

Two Carbon atoms form a Double Covalent Bond

The remaining open electrons on the Carbon atoms form Single Covalent Bonds with Hydrogen atoms.

At standard temperature and pressure, ethane is a colorless, odorless gas.

[image]

What is this molecule?

[image]

Methane CH₄.

A single carbon atom forms Single Covalent Bonds with 4 Hydrogen atoms.

The principal component of natural gas.

Burning methane in the presence of oxygen produces carbon dioxide and water.

It is a gas at normal temperature and pressure.  

Propane C³H⁸

Three Carbon atoms form Double Covalent Bonds and the remaining electrons on each Carbon atom form Single Covalent Bonds with Hydrogen elements.

Propane exists in nature as a gas but is compressed into a liquid for transportation.

[image]

What is this molecule?

[image]

Sodium Chloride NaCl

a.k.a. Salt

A Sodium atom and a Choloride atom form an ionic bond such that the Sodium atom gives up on of its electrons to the Chloride atom.  Then since the Sodium atom has a positive charge (because it gave up the negative electron) and Chloride atom has a negative charge (because it has an extra electron) they are attracted to each other.

[image]

What type of bonding is occuring?

[image]

[image]

Polar Bond or Hydrogen Bond

These two water molecules (H₂O) are called a dimer. 

The electronegativity of the Oxygen atom is much stronger than the electronegativity of the hydrogen atom. 

Therefore the electron shared between the hydrogen and the oxygen atom spends most of its time circling the Oxygen atom. 

This give the oxygen atom a slightly negative charge and the hydrogen a slightly positive charge.  This Polar Covalent Bond (Hydrogen Bond) is much weaker than Ionic or Covalent bonds.

Brain

There are 5 primary divisions of the brain?  What is the most anterior section of the brain?

[image]

#1 : The telencephalon (also known as the cerebrum) is part of the forebrain.  It is the most anterior section of the brain and in humans it is also the most superior section.

The cerebrum is composed of the following sub-regions:

• Cerebral cortex, or cortices of the cerebral hemispheres
• Basal ganglia, or basal nuclei
• Limbic System

This section is the newest evolutionary brain development.

Controls:

Voluntary Movement

Sensory Processing

Olfaction (in humans)

Language and Communication

Learning and Memory

There are 5 primary divisions of the brain?  What is the most posterior division of the brain?

[image]

#5 : The most posterior division of the brain before it becomes the spinal cord is the Myelencephalon. 

• It part of the hindbrain. 
• Commonly known as the Medulla Oblongata. 
• This is where the nerves decussate or swap sides so that the right side of the brain controls the left side of the body and vice versa.
• Controls muscle tone, pulse, blood pressure, respiration.

• Autonomic Functions
• Breathing
• Conduction Pathway for Nerve Tracts
• Digestion
• Heart Rate
• Swallowing
• Sneezing
