- Atoms & Equations
- Flame Test
- Potassium (K) = Lilac
- Sodium (Na) = Yellow
- Calcium (Ca) = Brick Red
- Copper (Cu) = Blue/Green
- Lithium (Li) = Reddish Orange
- Barium (Ba) = Apple Green
- Atomic Structures
- Protons
- Are in the nucleus of the atom
- Neutrons
- Atomic Structures
- Protons
- Are in the nucleus of the atom
- Neutrons
- No charge (Neutral)
- Has a mass of 1
- Made from two down quarks and one up quark.
- Relative Atomic Mass = number of Protons+ number of Neutrons
- Neutrons
- Positively Charged particle.
- Proton number= Electron number
- Made from two Up quarks and one down
- Are in the nucleus of the atom
- Electrons
- A charge of -1
- Mass of an electron is practically 0
- In the shells that orbit the nucleus of the atom
- Electronic configuration
- 2.8.8.1 would mean the element is in group 1 in the periodic table
- 2.8.8.5 would mean the element is in group 5

- Balancing Equations
- Take Potassium + Water --> Potassium Hydroxide + Hydrogen, for example
- K + H2O --> KOH + H2
- Separate each side of the equation like so.
- There is 1 K, 2 H's and 1 O
- There
is one more hydrogen on the one side of the equation. So a 2 must be put in
front of the H2O, making 2H2O
- 2H2O
But then we have two oxygens as well on the left side so a two must be put in
front of the KOH making 2KOH.
- Then
we have 2 potassiums on the right and only one on the left so a 2 must be put
in front of the K becoming 2K.
- 2K + 2H2O ------>2KOH + H2
- Then
we have 2 potassiums on the right and only one on the left so a 2 must be put
in front of the K becoming 2K.
- 2H2O
But then we have two oxygens as well on the left side so a two must be put in
front of the KOH making 2KOH.
- There
is one more hydrogen on the one side of the equation. So a 2 must be put in
front of the H2O, making 2H2O
- There is 1 K, 3 H's and 1 O
- There is 1 K, 2 H's and 1 O
- Separate each side of the equation like so.
- K + H2O --> KOH + H2
- More Examples?
- 2Na + Cl2 --> 2NaCl
- Na + Cl2 --> NaCl
- Na + Br2 --> NaBr
- 2Na + Br2 --> 2NaBr
- Cl2+ NaBr --> NaCl+ Br
- Cl2 + 2NaBr--> 2NaCl + 2Br
- Take Potassium + Water --> Potassium Hydroxide + Hydrogen, for example
