All materials are made up of molecules, and all molecules have tiny atoms, with positively charged protons, neutral neutrons, and negatively charged electrons.
所有的物质都是由分子构成的，而所有的分子内都有微小的原子、带正电荷的质子、中性的中子和带负电荷的电子。
The nucleus consists of uncharged neutrons and positively charged protons. negatively charged electrons travel around the nucleus in their orbits, similar to the way planets moving around the sun.
细小的原子核内含不带电荷的中子及带正电荷的质子，而带负电荷的电子则沿轨道环绕原子核运行，情况就好像行星环绕太阳运行一样。
When electric currents (electrons) are passed through positively-charged gasses (protons and neutron nucleuses) inside bulbs.
当电子流通过灯泡中带正电荷的气体(质子和中子核)。
Electrons are negatively charged with electricity, protons are positively charged.
电子是带负电荷的，质子是带正电荷的。
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 oxygen molecules form bubbles at the electrode, and the protons migrate away from the positively charged electrode.
该氧分子形成气泡在电极，和质子迁移脱离带正电荷的电极。
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。
Electrons are negatively charged with electricity, protons are positively charged.
电子带有负电荷，质子带有正电荷。
Electrons are negatively charged with electricity, protons are positively charged.
电子带有负电荷，质子带有正电荷。
