1. D'abord sur la couche K jusqu'à

1. D'abord sur la couche K jusqu'à saturation (c'est à dire .... électrons au maximum) .2. Puis sur la couche L jusqu'à saturation (c'est à dire ... électrons au maximum) 3. Puis sur la couche M jusqu'à 8 électrons (la couche M n'est alors pas encore saturée) . La dernière couche occupée par des électrons est appelée : les électrons de la couche externe sont appelés < électrons péri-phériques> . Les autres couches sont appelées . Remarque importante : ce sont seulement les électrons périphériques qui participent aux transformations chimiques. 3) Représentation de la structure électronique d'un atome ou d'un ion monoatomique . Pour spécifier la répartition des électrons sur les différentes couches électroniques d'un atome ou d'un ion monoatomique, on utilise une écriture conventionnelle appelée structure électronique ou configuration électronique. Pour représenter la structure électronique d'un atome : 1, On écrit entre parenthèses la lettre qui correspond à chaque couche . 2, On indique, en exposant, le nombre d'électrons de cette couche . 3, Les couches vides ne sont pas mentionnées

1. Firstly on the K layer to saturation (IE... electrons maximum). 2. Then on the L layer up to saturation (IE... electrons maximum) 3. Then on the M layer up to 8 electrons (the M layer is then not yet saturated). The last layer occupied by electrons is called : the outer layer electrons are called < electron peri-weather >. The other layers are called . Important note: these are only the peripheral electrons that participate in chemical transformations. (3) representation of the electronic structure of an atom or of a monatomic ion. To specify the distribution of electrons on the electronic layers of an atom or of a monatomic ion, using a conventional writing called electronic structure or electron configuration. To represent the electronic structure of an atom: 1, are written in brackets the letter that corresponds to each layer. 2 indicates, as a superscript, the number of electrons of this layer. 3, empty layers are not mentioned

1. First the K layer up to saturation (i.e. maximum .... electrons) .2. Then the layer L to saturation (i.e. maximum electron ...) 3. Then on the M shell to 8 electrons (the M layer is then not saturated). The last layer occupied by electrons is called: The outer layer the electrons are called <electron peri- pheric>. The other layers are called. Important note: it is only the outer electrons that participate in chemical transformations. 3) representation of the electronic structure of an atom or a monoatomic ion. To specify the electron distribution on the different electron shells of an atom or a monoatomic ion, a conventional writing using known electronic structure or electronic configuration. To represent the electronic structure of an atom: 1, We write in brackets the letter corresponding to each layer. 2, is indicated, stating the number of electrons in this layer. 3 Empty layers are not mentioned

1. first, on the layer to saturation (that is to say. electron maximum) 2. then the layer the saturation (i.e.,... the maximum electron). then the layer m up to 8 electrons, the layer m is not yet saturated). the last layer is occupied by electrons is referred to as the "outer layer".the electrons in the outer shell electrons are referred to as "suburban regions. the other layers are referred to as "internal layers. important note: this is only the outer electrons in chemical transformations. (3) representation of the electronic structure of an atom, or a monoatomic ion.to specify the distribution of the electrons in the atom layers (or a monoatomic ion uses a conventional writing called the electronic structure and electronic configuration. for the electronic structure of an atom, one letter is written in parentheses in each layer. 2 shows, stating,the number of electrons in the layer. three layers are not set, empty
