Let’s look closer at the sodium atom. Really close, so we could see. Atom is a neutral species, with 11 protons in the nucleus. We can find that information in the periodic table. 11 proton charge should ...

Collide, in the right orientation, with sufficient energy (more than the activation energy barrier)

Electron pair donor

• The independent variable is what you change throughout the experiment. Some examples of this may be temperature, pH, light levels or time. • The dependent variable is what is being measured. This is exp...

In an atom, protons have a +1 charge. Electrons that orbit the nucleus have a -1 charge, the number of electrons equals the number of protons so the charges cancel.
