Elements that are in groups of two or more and have the same charge are polyatomic ions. They exist to help bond together with other polyatomic ions and generally work to form complex compounds.Continue Reading
The most common example of a polyatomic ion is the hydroxide ion. It is an ion in which the oxygen and the hydrogen atoms are bonded together and work together to help each other form more complex bonds with other atoms. Elements that are in a polyatomic ion group always function as if they were a single ion and only carry a charge that a single ion would carry. They are generally not much bigger than a single element and do not take up much more space than a single one typically would.
They are generally around a neutral type of charge and function as the conjugate as an acid or a base, depending on what the ion needs. They can often change their function from an acid to a base because they are a combination of two elemental substances. They are the only type of cells in the universe that are able to easily switch between being acidic and alkaline without a major chemical process. They are able to do this to help the neutral ions that they stay around and are designed to help.Learn more about Atoms & Molecules
Charged groups of atoms are ions. Ions consist of one or more atoms that have gained or lost electrons. If the group gains electrons, it has a negative charge, and if it loses electrons, it becomes positive.Full Answer >
Gold nanoparticles are gold atoms in solution that have been created by the process of adding a reducing agent to gold ions. The resulting products have optical and electronic properties that make them useful in a variety of applications, including sensory probes, electronic conductors and therapeutic agents.Full Answer >
Ionic radius trends are seen within a group in the periodic table, where the radius gets bigger as one moves down a group and across a period, where the radius decreases among positive ions and increases among negative ions. The ionic radius is the radius of an atom's ion, and can be either larger or smaller than the radius of the neutral atom.Full Answer >
The bonds that hold the atoms in metals together are often described as being built upon metal ions that are floating in a sea of electrons. This is because the electrons in the outer shells, or valence shells, of metals are loosely held. The valence electrons are free to move from one atom to another.Full Answer >
