Why is carbon placed where is is in the periodic table?

Answer 1

Every element on the Periodic Table is placed due to their shell and electron configurations. Where the group (the columns in roman numerals) is the ammount of electrons (negatively charged atoms) in the outer shell of the element (in oxygens case 6) and the period number (the rows of the period table) is how many shells an element has.

To sum up, oxygen's nucleus has two shells surrounding it. In the outer shell there are 6 electrons. Making the electron configuration (The ammount of electrons in each shell starting from the innermost shell to the outermost shell) 2,6. Thus Peiod 2, Group 6.

Answer 2

The simple answer is because it has 4 valence electrons. Elements on the left hand side of the table have only 1 and elements on the right hand side have 7 or 8. 4 is half way between and thus in the middle of the table.

Answer 3

The table was originally set up by atomic weight. But look up "a brief history of the periodic table" to do further research

Answer 4

its placed where it is because of how many protons it has in its nucleus.

Answer 5

chemical properties
