Study Notes
Hydrogen Atom
- Hydrogen atom nucleus contains one particle.
- The diagram shows an atom of hydrogen.
Chemical Symbol for Hydrogen
- The chemical symbol for hydrogen is H.
Potassium and Water Reaction
- Potassium reacts with water to produce potassium hydroxide and hydrogen.
- One product of this reaction is potassium hydroxide.
Elements in Group 1 of the Periodic Table
- Elements in Group 1 of the Periodic Table include lithium (Li), sodium (Na), potassium (K), rubidium (Rb), caesium (Cs), and francium (Fr).
- These elements have similar properties and react in similar ways.
- The chemical symbol for potassium is K.
Identifying Elements
- Lithium (Li), water (Hâ‚‚O), and lithium hydroxide (LiOH) are substances, lithium is an element.
- To be an element, a substance must consist of only one type of atom and cannot be broken down by a chemical reaction.
Boron Atom Structure
- Boron atom includes two types of particles Y and Z.
- Particle Y is a proton, and particle Z is an electron.
- Boron is in Group 13 and Period 2 of the Periodic Table.
Measuring Temperature
- Thermometer A shows a temperature of 0°C.
- Thermometer B shows a temperature of -10°C.
- Thermometer C shows a temperature of 30°C.
Scientific Evidence
- Scientific statements require evidence to support them.
Using Indicators for Identification
- An indicator can be used to determine if substances are acids or alkalis.
- Example indicator is Litmus paper or universal indicator used to determine the pH of substances.
- If the liquids are acids the indicator will change colour.
pH Value for Aluminium Sulfate
- The pH value of the aluminium sulfate solution is around 3. This is because the indicator used (A and B) shows red as a result and red falls in the acid portion of the pH scale.
Plant Growth and Light
- Plants in different light conditions show differences in growth.
- Plant A (in light) shows better growth compared to plant B (in dark).
- Light is required for photosynthesis; hence, the growth in light is more pronounced than in the dark.
- Light is a form of energy.
- The Sun is a light source.
- Light is not the same as heat.
- The moon is not a light source.
Neutral Soil pH
- Neutral soil has a pH of 7.
