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.
Lithium, carbon, and neon are placed in period 2 of the periodic table because they all have 2 energy levels. Lithium has 2 electrons in its outer energy level, carbon has 2 electrons in its second energy level, and neon has a complete second energy level with 8 electrons. This pattern follows the periodic table's organization based on increasing atomic number and electron configuration.
The abbreviation for potassium is " K " in the periodic table. It is placed in group-1 of the periodic table.
Diamond is not listed on the periodic table as it is a form of carbon, which is located in Group 14 of the periodic table.
The lanthanides are a series of elements that are placed at the bottom of the periodic table. They are located in the f-block, specifically in the period below the main body of the periodic table. The lanthanides have atomic numbers 57-71.
Carbon is a chemical element with the symbol C and atomic number 6. It is nonmetallic and tetravalent—making four electrons available to form covalent chemical bonds. It belongs to group 14 of the periodic table. Carbon makes up only about 0.025 percent of Earth's crust. So, yes it is.
Lithium, carbon, and neon are placed in period 2 of the periodic table because they all have 2 energy levels. Lithium has 2 electrons in its outer energy level, carbon has 2 electrons in its second energy level, and neon has a complete second energy level with 8 electrons. This pattern follows the periodic table's organization based on increasing atomic number and electron configuration.
Astatine is placed in group-17 in the Periodic Table. Its symbol is At.
Compounds are not placed in the periodic table.
Actinoids are placed in a separate row under the periodic table.
NO!!! Carbon is No. 6 in the Periodic Table. Hydrogen is No. 1 in the Periodic Table.
If new elements are placed, then they would be appended in the periodic table. It won't disturb existing periodic table.
Metals are placed at the left. Non-metals are placed at right in periodic table.
CO3 is not placed in periodic table. Only elements are arranged in periodic table.
The first element in the periodic table of Mendeleev is hydrogen, not carbon.
No, carbon is not the first element on the periodic table of elements. Hydrogen is the first element on the periodic table.
All chemical elements are placed in the periodic table.
The abbreviation for potassium is " K " in the periodic table. It is placed in group-1 of the periodic table.
