I just know that periodic table have 118 elements. The mnemonic device: 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f, 6d, 7p, 6f, 7d,7f; To get

Övergångselement är de element som bildar stabila joner som har fyllts ofullständigt d-orbitaler. Till exempel är Zink och Notera:[Ar] = 1s22s22p63s23p6

This video covers most questions that wou 2011-11-21 (elements 1–104) Also subsection Periodic Table of the Elements, (elements 1–103) based on: G. J. Leigh, Editor, Nomenclature of Inorganic Chemistry , Blackwell Scientific Publications, Oxford, 1990. Why do elements not emit a continuous spectra and why does each element emit a particular set of lines which make up its line specturm? The answer lies in Bohr's Theory of the Atom and its structure.

As orbitals correspond to number of the subshell. 1 corresponds to s orbital. 2 corresponds to 2s 2p . 3 corresponds to 3s 3p 3d. 4 corresponds to 4s 4p 4d 4f. Thus 1s 2s 2p 3s 3p 3d the next will be 4s….

This means 4 valence electrons total. The nearest noble gas element to the potassium is argon (Ar).
