WebThe periodic table of the elements lists all of the chemical elements that have been discovered or created; they are organised into seven horizontal periods in the order of their atomic numbers, with the lanthanoids, lanthanum, 57, to lutetium, 71, and actinoids, actinium, 89, to lawrencium, 103 mentioned independently. WebJun 14, 2015 · The period or row numbers 1 through 7 are the energy levels of the elements. The s orbital holds a maximum of 2 electrons. The p orbital can hold 6. The d orbital can hold 10. The f orbital can hold 14 electrons. But, the orbitals overlap. The Madelung rule gives the order:

WebOct 29, 2024 · As you move from left to right across the periodic table, atoms have more electrons in their outer energy level and more protons in their nucleus. The greater attraction between the increased number of protons (increased nuclear charge) and electrons, pulls the electrons closer together, hence the smaller size.
