In a metallic bond, the electrons which make up the 'sea' of delocalised electrons are all of those from the outermost shell from the atoms. The other shells stay unaltered.
Electricity is the flow of electrons through a conductor. The three main substances that make up electricity in a typical circuit are conductors (such as metal wires), insulators (which restrict the flow of electrons), and a power source (such as a battery or generator) that provides the energy to move the electrons.
When visible light is absorbed by a metal, it can cause the metal to heat up or emit electrons in a process called the photoelectric effect.
Electrons do not make up the nucleus of an atom. They orbit the nucleus at various energy levels.
Yes, clothing can have electrons. Electrons are subatomic particles that make up atoms, and since all matter is made up of atoms, clothing can have electrons within its structure.
Moving electrons make up electric current, which is the flow of electric charge through a conductor. This movement of electrons is what generates electricity and powers various electrical devices and systems.
Air mainly consists of nitrogen, oxygen, and a small amount of other gases such as carbon dioxide. Water is made up of hydrogen and oxygen atoms bonded together to form molecules of H2O. Metals are composed of closely packed atoms arranged in a crystalline structure, typically involving a lattice of positive metal ions surrounded by delocalized electrons.
Ions
The free electrons within the metal cause metal to conduct electricity because they drift easily with an applied electric force. All metal conducts electricity.
Positive Ions
We generally understand metallic bonding as the dynamic electromagnetic activity that exists between the nuclei of metal atoms and the "free electrons" (delocalized electrons) that "wander" through the metallic matrix. The term free electrons is often associated with the idea of conduction electrons. Consider a "model" and what is happening within it to get a handle on the idea.Picture a "construct" or matrix of metal atoms. Now consider that not all the electrons within the matrix are "involved" in the structure, and take these electrons out. We end up with basically the same matrix, but without all those "free electrons" within it to wander around. That's the basic metallic crystal structure. Now dump all those delocalized ("free") electrons back into the sturcture and look at the way those electrons and the positively charged nuclei interact. That is metallic bonding.Metallic bonding is a "general" bonding where all the positively charged nuclei are pulling and tugging on all of the free electrons as those electrons move about in the matrix. No single atomic nucleus forms a metallic bond with an electron, but rather it is a "group effort" or "group effect" of all the atomic nuclei and all those delocalized electrons. It might be viewed as a quantum mechanical phenomenon rather than a "physical" one. A link can be found below for more reading.
All metals don't stick to magnets because they are alike and if they are alike they repel each others. ^sucks^ The three pure metals that don't stick to magnets are copper, silver, and gold.
Metals are held together by metallic bonds. Metallic bonds consist of the attraction of the free-floating valence electrons for the positively charged metal ions. These bonds are the forces of attraction that hold metals together. Metals are made up of closely packed cations rather than neutral atoms. The valence electrons of metal atoms can be modeled as a sea of electrons. The valence electrons are mobile and can drift freely from one part of the metal to another. Metallic bonds consist of the attraction of the free-floating valence electrons for the positively charged metal ions. These bonds are the forces of attraction that hold metals together.
Since calcium is a metal, it gives up electrons.
There are many different types of metal, so it depends on the metal. If it is a metal such as pure copper, it is made up of only copper atoms. If it is a metal like bronze, it is made up different kinds of atoms like copper and tin. If it is an alloy, there are many different kinds of atoms contained within the metal.
== == When metals react with other elements, the atoms of the metals give up their valence electrons.

Ionic bonds are formed when electrons are transferred from one atom to another, creating positively and negatively charged ions that are attracted to each other. This transfer typically occurs between a metal and a non-metal, with the metal giving up electrons to the non-metal. The resulting attraction between the positive and negative ions forms the ionic bond.
