Physical and Chemical Properties of Aldehydes and Ketones, Oxidation states of d and f Block Elements, Electronic Configuration of Group 14 Elements, Physical and chemical properties of Group 16 elements. They are one electron short of having full outer s … It will be helpful now to look at electron configurations also in the context of the periodic table. Publish your article. All halogens have seven electrons in their outermost shell comprising completely filled s orbital and p orbital with 5 electrons. There is more attraction which makes it easier to gain an extra electron. For example, all the elements in group 13, beginning with boron, end with “p1”. The penultimate shell of carbon contains the s 2 electrons, silicon has s 2 p 6 electrons and germanium contains the s 2 p 6 d 10 electrons and is unsaturated. Atoms gain, lose, or share electrons in order to obtain the stable octet configuration. Write the subshell electronic configuration of the element. Rhubidium (Rh) 6. , Electrons and Sublevels  Electron Configurations and the Periodic Table  Writing Electron Configurations  Box and Arrow Configurations using Pauli Exclusion Principle and Hund's Rule   Quantum Numbers, Electron Configurations and the Periodic Table, Electron configurations and the periodic table. Write atomic number and electronic configuration of ‘X’. For instance, hydrogen exists as a gas, while other ele… Which group of elements has the valence configuration of {eq}ns^2np^2 {/eq}? The halogens all have the general electron configuration n s 2n p 5, giving them seven valence electrons. google_ad_slot = "2147476616"; They use these electrons in the bond formation in order to obtain octet configuration. The element misses out on the octet configuration by one electron. The elements of Group 17 (fluorine, chlorine, bromine, iodine, and astatine) are called the halogens. There are 118 elements … These five toxic, non-metallic elements make up Group 17 of the periodic table and consist of: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At). As all the elements in group 14 have 4 electrons in the outermost shell, the valency of Group-14 elements is 4. (b) This element is a non-metal as it gains one electron to complete its outermost shell and elements which gain electrons … The electronic configurations of the elements in group 1: The atoms of all group 1 elements have similar chemical properties and reactions because they all have one electron in their outer shell. The form of the periodic table is closely related to the electron configuration of the atoms of the elements. Although astatine is radioactive and only has short-lived isotopes, it behaves similar to iodine … Table 2: Reaction of halogens with iron wool. An element X (atomic number 17) combines with an element Y (atomic number 20) to form a compound. Also write group number, period number and valency of ‘X’. Learn more about Group 17 Elements here. The halogens all have the general electron configuration ns2np5, giving them seven valence electrons. For example, fluorine, chlorine, bromine, and iodine routinely accept an electron to achieve the more stable electronic configuration of a noble gas, obtaining eight electrons in their valence shells instead of seven. The reaction is slow. The first example occurs in the case of the lanthanoids (elements having atomic numbers between 57 and 71).The lanthanoids have the general electron configuration [Kr]4d 10 4f i 5s 2 5p 6 5d 0 or 1 6s 2. where i is a number between 0 and 14. These elements tend to show patterns in atomic radius, ionization energy, and electronegativity.
