Study Notes
###Â Eukaryotic Cell Component
- The nucleus is found only in eukaryotic cells.
###Â Prokaryotic Cells
- Prokaryotic cells do not have a nucleus.
###Â Passive Movement of Water
- Osmosis is the passive movement of water through a semi-permeable membrane.
###Â Maximum Electrons in First Energy Level
- The maximum number of electrons in the first energy level (shell) is two.
###Â Atomic Models and Developers
- John Dalton proposed the atomic model as a solid sphere.
- J.J. Thomson discovered the electron and proposed the plum pudding model.
- Rutherford conducted the gold foil experiment which led to the discovery of the nucleus and the nuclear model.
- Bohr proposed the planetary model, where electrons orbit the nucleus in specific energy levels.
###Â Reactive Metals
- Group 1 on the periodic table contains very reactive metals, also known as alkali metals.
###Â Reactivity of Halogens
- Reactivity decreases down Group 7, which contains halogens.
###Â Magnification Formula
- Magnification is calculated using the formula: Magnification = Image Size / Actual Size.
