| Atoms, the smallest particles of matter that retain the properties of the matter, are made of protons, electrons, and neutrons. | 原子是保持物质特性的最小物质粒子，由质子、电子和中子组成。 |
| Protons have a positive charge, Electrons have a negative charge that cancels the proton's positive charge. | 质子带有正电荷，电子带有负电荷，可以抵消质子的正电荷。 |
| Neutrons are particles that are similar to a proton but have a neutral charge. | 中子是一种与质子相似但带中性电荷的粒子。 |
| 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. | 除了电荷相同的粒子相互排斥，电荷相反的粒子相互吸引之外，正电荷和负电荷之间没有区别。 |
| If a solitary positive proton and negative electron are placed near each other they will come together to form a hydrogen atom. | 如果把一个单独的正质子和负电子放在一起，它们就会结合成一个氢原子。 |
| 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. | 这种斥力和吸引力（静止带电粒子之间的作用力）被称为静电力，理论上可以延伸到无限远，但随着粒子间距离的增加会被稀释。 |
| 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. | 当一个原子缺少一个或多个电子时，它就会带正电荷，而当一个原子至少多了一个电子时，它就会带负电荷。 |
| Having a positive or a negative charge makes an atom an ion. | 带有正电荷或负电荷的原子就是离子。 |
| Atoms only gain and lose protons and neutrons through fusion, fission, and radioactive decay. | 原子只能通过聚变、裂变和放射性衰变来获得和失去质子和中子。 |
| 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. | 虽然原子是由许多粒子组成的，物体也是由许多原子组成的，但它们在排斥和吸引方面的表现与带电粒子类似。 |
| In an atom the protons and neutrons combine to form a tightly bound nucleus. | 在原子中，质子和中子结合成一个紧密结合的原子核。 |
| 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). | 原子核周围有大量的电子云，这些电子在一定距离内环绕着原子核，但在电磁吸引力（前面讨论过的静电力）的作用下，电子云被固定在质子附近。 |
| 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. | 原子云以一系列重叠的壳/带形式存在，其中内价带充满电子并与原子紧密结合。 |
| The outer conduction bands contain no electrons except those that have accelerated to the conduction bands by gaining energy. | 外导带不包含任何电子，只有那些因获得能量而加速到导带的电子除外。 |
| With enough energy an electron will escape an atom (compare with the escape velocity of a space rocket). | 只要有足够的能量，电子就会逃离原子（与太空火箭的逃逸速度相比）。 |
| When an electron in the conduction band decelerates and falls to another conduction band or the valence band a photon is emitted. | 当传导带中的电子减速并落到另一个传导带或价带时，就会发射出光子。 |
| This is known as the photoelectric effect. | 这就是所谓的光电效应。 |

| When an electron in the conduction band decelerates and falls to another conduction band or the valence band a photon is emitted. | 当传导带中的电子减速并落到另一个传导带或价带时，就会发射出光子。 |
| This is known as the photoelectric effect. | 这就是所谓的光电效应。 |
| Atoms, the smallest particles of matter that retain the properties of the matter, are made of protons, electrons, and neutrons. | 原子是保持物质特性的最小物质粒子，由质子、电子和中子组成。 |
| Protons have a positive charge, Electrons have a negative charge that cancels the proton's positive charge. | 质子带有正电荷，电子带有负电荷，可以抵消质子的正电荷。 |
| Neutrons are particles that are similar to a proton but have a neutral charge. | 中子是一种与质子相似但带中性电荷的粒子。 |
| 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. | 除了电荷相同的粒子相互排斥，电荷相反的粒子相互吸引之外，正电荷和负电荷之间没有区别。 |
| If a solitary positive proton and negative electron are placed near each other they will come together to form a hydrogen atom. | 如果把一个单独的正质子和负电子放在一起，它们就会结合成一个氢原子。 |
| 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. | 这种斥力和吸引力（静止带电粒子之间的作用力）被称为静电力，理论上可以延伸到无限远，但随着粒子间距离的增加会被稀释。 |
| 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. | 当一个原子缺少一个或多个电子时，它就会带正电荷，而当一个原子至少多了一个电子时，它就会带负电荷。 |
| Having a positive or a negative charge makes an atom an ion. | 带有正电荷或负电荷的原子就是离子。 |
| Atoms only gain and lose protons and neutrons through fusion, fission, and radioactive decay. | 原子只能通过聚变、裂变和放射性衰变来获得和失去质子和中子。 |
| 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. | 虽然原子是由许多粒子组成的，物体也是由许多原子组成的，但它们在排斥和吸引方面的表现与带电粒子类似。 |
| In an atom the protons and neutrons combine to form a tightly bound nucleus. | 在原子中，质子和中子结合成一个紧密结合的原子核。 |
| 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). | 原子核周围有大量的电子云，这些电子在一定距离内环绕着原子核，但在电磁吸引力（前面讨论过的静电力）的作用下，电子云被固定在质子附近。 |
| 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. | 原子云以一系列重叠的壳/带形式存在，其中内价带充满电子并与原子紧密结合。 |
| The outer conduction bands contain no electrons except those that have accelerated to the conduction bands by gaining energy. | 外导带不包含任何电子，只有那些因获得能量而加速到导带的电子除外。 |
| With enough energy an electron will escape an atom (compare with the escape velocity of a space rocket). | 只要有足够的能量，电子就会逃离原子（与太空火箭的逃逸速度相比）。 |
