Foundation of chemistry part i offers a beginner-friendly look at the periodic table, with basic symbol familiarity. Explore atomic structure, group properties, and practice questions to build understanding.
Explore how the periodic table groups elements by groups and periods, using atomic number and outer-shell electrons, and how metals, nonmetals, and oxidation numbers differ.
Explore atomic structure using Bohr's model, identifying protons, neutrons, and electrons. Learn electron configuration across shells and how atomic number and mass number relate to the periodic table.
Explore atomic structure and electron configuration for boron, oxygen, and fluorine in the same period, compare group and period numbers, and review atomic radius and ionization energy trends.
Learn to determine atomic structure and electron configuration for magnesium, aluminium, and chlorine, assign group and period numbers, and compare atomic radius, ionization energy, and electronegativity across a period.
Moving left to right across a period, elements share the same shell count while valence electrons rise, increasing core attraction and reducing atomic radius, with ionization energy and electronegativity rising.
Explore atomic structure and electron configuration of group 1 elements, draw shells around the core, and analyze atomic radius, ionization energy, and electronic negativity.
Explore atomic structures and electron configurations of fluorine, chlorine, and bromine, and compare their subatomic properties, including atomic radius, ionization energy, and electronegativity versus electropositivity, to explain top-to-bottom trends.
In a group, elements share the same number of valence electrons; moving down increases atomic radius and lowers first ionization energy, making outer electrons easier to remove and increasing electropositivity.
Review how periods and groups define the periodic table, explain atomic number, mass number, protons, neutrons, and electrons, and apply the 2n^2 shell rule using NaCl as an example.
Thank you for checking in Fundamental Chemistry Part I - the Periodic Table.
Who should take this course?
This course is good for those who want to learn the key concepts in the Periodic Table and element(s)' properties based on certain trends down the group(s) as well as across the period(s). Thereafter, by applying those concepts, you should be able to conduct analysis and predict the behaviour of the element(s) towards the other ones and in chemical reactions.
Please be advised that this course will not make you an expert in chemistry, but it helps you to get a better sense of the way certain matters in chemistry (i.e., chemical reactions) happen.
Why can Chemistry be challenging?
Many people chemistry difficult, and with good reasons. Chemistry is difficult if one does not have in-depth understanding of the basics. Chemistry is a multi-disciplinary subject in which integrating the basics, terminology, mathematics, and visualization required to make sense out of it. In light of this, the Periodic Table has been considered as the building block of the subject which knowing it can make huge difference in your chemistry world.
So, how can you learn this course effectively?
I suggest you doing the following:
While watching videos, you should take notes if needed.
Try to do the practice questions on your own and if there should there be any questions, you can leave a message in 'Q&A' part and I will try my best to reply as soon as I can.
When working on the practice questions, remember using the guidelines - provided as summary at the end of each part.
After completing the Exercises, watch the next video for the answers. You should watch the steps I take to do them and compare them with yours.
Last but not least, try to practice because as said 'Good Practice Makes you Perfect'!
Finally, if you should have any questions about this course/concept, you are welcome to send me message in here.
That was all for my introduction. Happy learning!
