The first option i hope this helps
Chemical change: is any change the results formation of new chemical substances
Physical changes: rearranged molecules but affect internal structures
Based on the equation of the reaction, for every 1 mole of oxygen that reacts, 4 moles of electrons are transferred.
<h3>What are redox reactions?</h3>
Redox reactions are reactions in which oxidation and reduction reactions occur simultaneously to the same extent.
Oxidation reactions involves addition of oxygen or removal of oxygen.
The equation of reaction when one mole of oxygen accept ectrons is given below:

Therefore, for every 1 mole of oxygen that reacts, 4 moles of electrons are transferred.

I'm an 11th grader taking physical science so I'm currently learning this.
First you need to have your periodic table labeled.
My teacher made us do it with 3 different colors. 2 for non-metals and 1 for metals as the picture I have with this answer shows.
Next you have to know the different parts of an element on the periodic table.
The top left of an element is the atomic number.
The middle of an element is the chemical symbol, which is the abbreviation of the element
The next word you see near the bottom middle is the name of the element
And then the bottom of the element is the atomic mass.
Ex:
Hydrogen
1. Atomic Number : 1
2. Symbol : H
3. Name: Hydrogen
4. Atomic Mass : 1.007....
You read a periodic table like you read a book, left to right.
If there's anything in particular you need to know about the periodic table, let me know
