Isotopes

Isotopes

The atoms of a chemical element can exist in different types. These are called isotopes. They have the same number of protons (and electrons), but different numbers of neutrons. For example, an atom with 6 protons must be carbon, and an atom with 92 protons must be uranium. Different isotop.....

An Isomer

An Isomer

An isomer in chemistry is a chemical that has the same molecular formula as another, but it has a different arrangement of atoms in space. They are molecules with the same chemical formula but different chemical structures. Different isomers have different chemical properties (that is, they may l.....

Ionic Bond

Ionic Bond

An ionic bond is the electrostatic forces of attraction between a non-metal and a metal ion in a giant ionic crystal lattice. It is a type of linkage formed from the electrostatic attraction between oppositely charged ions in a chemical compound. This occurs when charged atoms (ions) attract. Ion.....

Ion Channels

Ion Channels

Ion channels are pore-forming proteins that help to establish and control the small voltage gradient across the plasma membrane of all living cells by allowing the flow of ions down their electrochemical gradient. They are present in the membranes that surround all biological cells. They are pres.....
