Protons have a positive charge, neutrons have no charge, and electrons have a negative charge. The number of protons determines the element of the atom, while the number of neutrons can vary (resulting in different isotopes of the same element). Electrons exist in energy levels or shells ...

a有 但是 是坏的 But has is bad[translate] a也就是说铁元素原子核中的中子与质子要比其它所有元素原子核中的中子与质子靠近得更紧密,其中子与质子间的强相互作用力也最大,因而当其向同一个方向排列时,其也具有最大的磁场。 In other words, in the hard element atomic nucleus neutron and the proton ...
Such anomalies are due to the relative abundance of the "isotopes" or varieties of each element. All the isotopes of a given element have the same number of protons, but differ in their number of neutrons, and hence in their atomic mass. The isotopes of a given element have the same ...
aIndividuals receiving bilateral training showed a reduction in movement time of the impaired limb and increased upper limb functional ability compared to individuals receiving unilateral training. 接受双边训练的个体显示了对被削弱的肢体的运动时间的减少并且增加了上部肢体功能能力与接受单边的训练的个体比较。[...
First, build a computer model of the nucleus-series data, simulation center in the nucleus of neutrons and protons is how they are arranged and distributed, especially in the center of an iron 56, which sub-space with the proton shared between the neutron and proton single account How much ...
