Coal, petroleum and natural gases are known as fossil fuels. Coal comes from the partly decayed remains of ancient plants that became buried millions of years ago and were subjected to great pressure. As these fossil fuels take time millions of years to form, the carbon in them tends to recycle very slowly. In as much as they take time to form, they are been used up rapidly.
For the first section take a look at a periodic table and fill it in . it tells u everything u need! i’ll send a example . the number of protons and electrons are the same. for every one ex: proton number= 3 electron number= 3 ! to determine valence electrons it’s differs on what column it is in on the periodic table. i’ll put in a picture to help aswell ! for the atom family number there is 18 of them. you would have to choose them based on the element. as for the dot structure. just search up a picture on line of that element dots structure and it will deffienly tell u and draw it. for the last ion part i would search it up on the internet! this is a lot of work but i know u can do it . sorry i couldn’t be or more help! if u have any other questions let me know i’ll be happy to guide u
