Redox reactions form the basis of many fundamental processes of life. Without them, neither cellular respiration nor ...

When two objects have the same static charge, they move away or repel one another. Rubbing a balloon on hair causes electrons to move from your hair onto the balloon, giving the balloon a negative ...

The “lead” of a pencil is actually made of a substance called graphite which is made of carbon atoms. The picture shows a close-up of one carbon atom. A hydrogen atom has one proton as the nucleus and ...

For example, a negative charge causes a repulsive force on a neighbouring ... Since electrons are so small and one electron will not have much of an effect anywhere, it is more useful to refer ...

Because electrons have a negative charge, this can cause the charge of ... This proton-coupled electron transfer (PCET), as it is known, does not produce any change in charge – the most ...

A stable atom has a net charge of 0. In other words, it has an equal number of protons and electrons. The positive protons cancel out the negative ... atom's second shell. An electron may "drop ...
