To balance out this positive charge, it needs 13 electrons. Aluminum has an atomic number of 13. Valence Electrons: 3s 2 p 1 Electron Dot Model. Electron Affinity – Aluminium. The ground state electron configuration is [Ne]3s 2 3p 1. One +3 oxidation state for Aluminum can be found in the compound aluminum oxide, Al 2 O 3. Question. Compounds of aluminum follow similar trends. The other two are +1 and +2. aluminum valence electrons Thus, it contains 13 electrons. Electronegativity (Pauling scale) The tendency of an atom to attract electrons towards itself, expressed on a relative scale. 3. Video: Aluminium Electron Configuration Notation The configuration notation provides an easy way for scientists to write and communicate how electrons are arranged around the nucleus of an atom. The atoms of metal elements are characterized by the presence of valence electrons, which are electrons in the outer shell of an atom that are free to move about. When the charges are equal and opposite the atoms will bond as #Al_2O_3#. 0 Answers/Comments. Asked 11/12/2014 9:23:20 AM. That means that it has 13 protons. It is these "free electrons" that allow metals to conduct an electric current. We will need 2 aluminum atoms to get a +6 charge and 3 oxygen atoms to get a -6 charge. This is because the element’s atomic number is 13, reflecting the fact that it has 13 electrons and 13 protons. Aluminum has three oxidation states. 2 of them fall into the first energy level and 8 fall into the second energy level. Aluminum has three valence electrons. Its outermost shell is 3 and thus has 3 valence electrons from subshells 3s and 3p. Electron affinity The energy released when an electron is added to the neutral atom and a negative ion is formed. This answer has been confirmed as correct and helpful. Electron affinity of Aluminium is 42.5 kJ/mol. Aluminum #s^2p^1# has 3 valence electrons and an oxidation state of +3 or #Al^(+3)# Oxygen #s^2p^4# has 6 valence electrons and an oxidation state of -2 or #O^(−2)# The common multiple of 2 and 3 is 6. Oxidation States. Updated 11/12/2014 9:49:56 AM. Maths. s. Ourmine|Points 10| Log in for more information. Therefore the Aluminium electron configuration will be 1s 2 2s 2 2p 6 3s 2 3p 1. The valence shell of aluminum has three electrons, and per the octet rule, these three electrons are lost resulting in just 10 electrons and 13 protons.Aluminum then has three excess protons so the charge of a base aluminum ion is 3+. Aluminum trichloride (AlCl 3), aluminum hydride (AlH 3), and aluminum hydroxide (Al(OH) 3) indicate a valence of three for aluminum, with six valence electrons in the bonded molecule.However, the stability of aluminum hydride ions (AlH 4 –) indicates that Al can also support an octet of valence shell electrons. Chemical Properties of Aluminum. The charge of an aluminum ion is typically 3+. Aluminum with 13 electrons has a configuration of {eq}\rm \rm 1s^2~2s^2~ 2p^6~3s^2 ~3p^1 {/eq}. The halogens all have seven valence electrons. In chemistry and atomic physics, the electron affinity of an atom or molecule is defined as: the change in energy (in kJ/mole) of a neutral atom or molecule (in the gaseous phase) when an electron is … Electrical conductivity in metals is a result of the movement of electrically charged particles. Which element has the fewest valence electrons available for bonding? These electrons fall into energy levels. The most common one is +3. The electron configuration for Aluminum is 1s 2 2s 2 2p 6 3s 2 3p 1. Edited by jeifunk [11/12/2014 9:49:55 AM], Confirmed by jeifunk [11/12/2014 9:49:56 AM]
