As such, it governs-among other things-the energy levels of an atom formed from negatively charged electrons and a positive nucleus.
就此而论，它控制由带负电荷的电子与正电荷原子核的形成的原子能级。
That means it lacks sufficient energy, like x-rays and gamma rays, to remove an electron from an atom or a molecule to make a charged particle that can damage DNA and biomolecules.
也就是说，微波辐射与X射线和伽玛射线不同，是不具有足够的能量的，从而不会使原子或分子失去电子而变成带电粒子，造成DNA及其它生命分子的损坏。
The remainder of the atom from which one or more electrons are removed must be positively charged.
如果从原子中移走一个或多个电子，则该原子的其余部分必定带正电。
The number of protons, which are positively charged particles, determines the chemical properties of the atom, e. G. Whether it will bond with other atoms to form molecules.
组成，带正电质子的数目，决定了该原子的化学特性，例如它会否和其他原子结合成分子等。
The multiply charged ions (MCI) play an important role in those fields, such as atom and molecule physics, surface science, plasma physics, nuclear physics, and astrophysical.
多重离化态离子在原子分子物理、表面科学、等离子体物理、核物理以及天体物理中，扮演着重要角色。
If one of more electrons be moved, the atom is said to be positively charged.
如果原子失去了一个或多个电子，我们就说该原子带正电荷。
How does an atom become charged?
原子是怎样带电的？
In a neutral atom, the protons in the nucleus are balanced by the electrons. An atom that has gained or lost electrons becomes negatively or positively charged and is called an ion.
在中性原子中，电子数和原子核的正电荷数相等，但有些原子可以拥有比原子核的正电荷更多或更少的电子，从而原子就带上负的或正的电荷，这类带电的原子称为离子。
The atom is a basic unit of matter consisting of a dense, central nucleus surrounded by a cloud of negatively charged electrons.
原子是物质的基本单位组成了一个密集，中央核周围有云带负电荷的电子。
The atom is a basic unit of matter consisting of a dense, central nucleus surrounded by a cloud of negatively charged electrons.
原子是物质的基本单位组成了一个密集，中央核周围有云带负电荷的电子。
