| Atoms, the smallest particles of matter that retain the properties of the matter, are made of protons, electrons, and neutrons. |
Les atomes qui sont des particules de matiere qui retiennent les proprietes de la matiere, sont faits de protons, electrons et neutrons |
| Protons have a positive charge, Electrons have a negative charge that cancels the proton's positive charge. |
Les protons ont une charge positive, les Electrons ont une charge negative, qui fait eliminer la charge positive des protones |
| Neutrons are particles that are similar to a proton but have a neutral charge. |
Les neutrons sont des particules qui ressemblent aux protons mais ont une charge neutre. |
| There are no differences between positive and negative charges except that particles with the same charge repel each other and particles with opposite charges attract each other. |
Il n'y a pas de differences entre les charges positives et negatives sauf les particules avec le meme repel de charge entre eux et particules avec a charges opposees attirent l'un l'autre. |
| If a solitary positive proton and negative electron are placed near each other they will come together to form a hydrogen atom. |
Si un proto positif solitaire et electron negatif sont place l'un a cote de l'autre ils vont former un atome d'hydrogene. |
| This repulsion and attraction (force between stationary charged particles) is known as the Electrostatic Force and extends theoretically to infinity, but is diluted as the distance between particles increases. |
La repulsion et attraction (Force entre des particules charges stationaires)est connue comme la Force Electrostatique et elle est infinie, mais diluee comme la distance entre les particules augmente. |
| When an atom has one or more missing electrons it is left with a positive charge, and when an atom has at least one extra electron it has a negative charge. |
Quand un atome a un ou plus electtons manquant il est laisse avec une charge positive, et quand un atome a au moins un electron Extra il a une charge egative. |
| Having a positive or a negative charge makes an atom an ion. |
Ayant une charge positive ou negative fait d'un atome un ion. |
| Atoms only gain and lose protons and neutrons through fusion, fission, and radioactive decay. |
Les atomes recoivent et perdent des protons et neutrons a travers la fusion, fission et degat radioactif. |
| Although atoms are made of many particles and objects are made of many atoms, they behave similarly to charged particles in terms of how they repel and attract. |
Bienque les atomes soient construits de plusieurs particules et objets sont faits de plusieurs atomes, ils comportent aux particules charges de facon similaire concernant la facon dont ils repelent et attirent. |
| In an atom the protons and neutrons combine to form a tightly bound nucleus. |
Dans un atome les protons et neutrons sont combines pour former un nucleus serre. |
| This nucleus is surrounded by a vast cloud of electrons circling it at a distance but held near the protons by electromagnetic attraction (the electrostatic force discussed earlier). |
Ce nucleus est entoure d'une nuage vaste d'electrons l'encirclant par distance mais tenu pres des protons d'une atraction electromagnetique (Force electrostatique discutee avant). |
| The cloud exists as a series of overlapping shells / bands in which the inner valence bands are filled with electrons and are tightly bound to the atom. |
La nuage existe comme une series de coquilles/bandes surpassant ou les bandes de valence interne sont remplies d'electrons et sont serres a l'atome. |
| The outer conduction bands contain no electrons except those that have accelerated to the conduction bands by gaining energy. |
Les bandes de conduction exterieure ne contiennent pas d'electrons sauf ceux qui ont accelere aux bandes de conduction en gagnant de l'energie. |
| With enough energy an electron will escape an atom (compare with the escape velocity of a space rocket). |
Avec assez d'energie un electron va echapper d'un atome (comparer a la velocite echappant d'un satellite. |
| When an electron in the conduction band decelerates and falls to another conduction band or the valence band a photon is emitted. |
Quand un electrone a la bande de conduction decelere et tombe a une autre bande de conduction ou la bande de valence un photon est emis. |
| This is known as the photoelectric effect. |
Ca est conne comme effet photoelectrique. |
