Which electrons from the metal make up the delocalized electrons?

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.

∙ 13y agoThis is because the electrons cannot be definitively assigned as 'belonging' to any one atom. The overall total of electrons is insufficient to fill all the valence shells of all the metal atoms, but due to the constant movement of electrons around the various atoms, the atoms are stabilized.

Why doesn't wood and metal attract to static electricity?
Static electricity is a build up of electrons. Static means still or stationary. Electrons on metal can not be stationary as the metal is such a good conductor of electricity. To remove static electricity after dragging your feet on a nylon carpet just touch a metal appliance or pipe eg a tap. Wood is generally porous so electrons again do not build up but ebony will build a static charge as it is a very dense wood. Electrons build up on plastic as it is a poor conductor. The electrons are static and a charge builds. Static electricity is caused by electrons being knocked off or building up on objects that are not normally good conductors.
Does copper conduct heat well because it is shiny?
Copper does not conduct well because of its shininess, but because a large fraction of the electrons in copper are in delocalized orbitals and therefore can move rapidly from one side of a copper object to another under the influence of an electric field.
What are the moving charges that make up an electric current?
Electrons.
Joan placed a metal spoon in a pot while boiling some water to make soup After a while she found that the metal spoon is too hot to pick up She wondered how the metal spoon became so hot?
Metal is a good conductor. Loosely held electrons can bump into other atoms and help transfer thermal energy.Transfer of heat.
What are tiny particles that make up electricity?
Tiny particles that make up electricity are called electrons. Electrons are negatively charged particles that orbit the nucleus of an atom. When these particles are in motion, they create an electric current that can be harnessed for various purposes.
Why do you think substances that are made up pf molecules do not normally conduct electricity?
because they do not have delocalized electrons
What causes metal to conduct electricity?
The free electrons within the metal cause metal to conduct electricity because they drift easily with an applied electric force. All metal conducts electricity.
What is a metallic is bond?
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.
How are particles in a piece of metal held together?
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.

Why can metals like copper malleable and ductile?
Metals are both ductile and malleable because of their electrons. The electrons move about the entire structure fo the metal, when the metal is pulled or smashed it doesnt crack because there are no similarly charged ions facing each other for repulsion. Picture this ionic representation of Sodium Cholride NaCl (Table Salt)Pretend theres circles around the signes +-+-+-+-+- -+-+-+-+-+ When this is hit down the positive charges will line up causing the structure to have the same charges facing each other which make it split. A metal has electrons flowing like a sea. Picture a structure of atoms with electrons zipping all over the place. When the metal is smashed or pulled the charges wont line up causing no repulsion. the another answer is:- High degrees of ductility occur due to metallic bonds, which are found predominantly in metals and leads to the common perception that metals are ductile in general. In metallic bonds valence shell electrons are delocalized and shared between many atoms. The delocalized electrons allow metal atoms to slide past one another without being subjected to strong repulsive forces that would cause other materials to shatter.
What happens to calcium's electrons during ionic bond?
Since calcium is a metal, it gives up electrons.
Is sodium a proton?
No. sodium is an alkali metal element that has 12 neutrons, 11 protons and 11 electrons in it's compositional make up.
When metal react with other elements what happens to the valence electrons of the metal atom?
== == When metals react with other elements, the atoms of the metals give up their valence electrons.
What types of atoms make up an ionic compound?
a metal and a non metal, provided the electronegativity difference between the two is more than 1.8
