Delocalized valence electrons moving between nuclei become detached from their parent atom. The metal is held together by the strong forces of attraction between the delocalized electrons and positive nuclei.

Delocalised valence electrons moving between nuclei contribute to the metallic properties of a material by allowing for high electrical conductivity and thermal conductivity. These electrons are free to move throughout the structure, creating a "sea of electrons" that can carry electric current or heat energy efficiently.

What happened to the number of valance electrons move from left to right on the periodic table?
the number of valence electrons increases on moving from left to right in periodic table.Group 1 has 1 valence electron and group-18 has 8 valence electrons.
What are valence electrons and shells?
Valence electrons are the ones which participate in chemical reactions in some way, either by moving from one atom to another, or by being shared with another atom. They are found in the outer shell of an atom (there are usually inner shells with other electrons that are not valence electrons, although in the lightest elements, there are no inner shells and all electrons are valence electrons).
What happends to the valence electrons is they are moved from left to right in the periodic table?
As you move from left to right across the periodic table, the number of valence electrons increases by one at a time. This increase results in a higher effective nuclear charge, which leads to increased attraction between the nucleus and the electrons. This can affect the reactivity and chemical properties of the elements in that period.
What term is used for the electrons in the outermost shell?
there called valence electrons
Do freely moving valence electrons account for electrical conductivity in metals?
Yes, freely moving valence electrons account for electrical conductivity in metals. These electrons are not bound to specific atoms and can move throughout the metal lattice, creating a flow of electric charge when a voltage is applied. This mobility of electrons allows metals to conduct electricity efficiently.
What does a Aluminium bond look like?
An aluminium bond involves the sharing of electrons between aluminium atoms to form a metallic bond. This results in a sea of delocalized electrons moving freely between the atoms, giving aluminium its characteristic properties such as conductivity and malleability.
What are the moving particles that make up electricity?
Free Delocalised Electrons or Ions in Liquids (or in a Molten Substance).
When moving down a group in the periodic table what does the number of valence electrons do?
The number of valence electrons increases by one as you move down a group in the periodic table. Valence electrons are the electrons in the outermost energy level of an atom, and they determine the chemical properties of an element.
What are valence and electrons?
Valence electrons are the ones which participate in chemical reactions in some way, either by moving from one atom to another, or by being shared with another atom. They are found in the outer shell of an atom (there are usually inner shells with other electrons that are not valence electrons, although in the lightest elements, there are no inner shells and all electrons are valence electrons).

Why are metals conductors of heat?
Because of their many valence electrons. The free-moving electrons transmit heat quickly.
Why does metalic bonding cause metals to conduct electric current?
Metallic bonding involves positive metal cations surrounded by a 'sea' of delocalised electrons. These delocalised electrons are able to move freely as they are not joined to one particular atom. Normally, these electrons are moving completely randomly and so their resultant velocity is zero. However, when a potential difference is applied, these electrons gain a small resultant drift velocity that enables them to flow as an electric current.
How does the valence electrons increasing?
When moving left to right across a period on the periodic table, the number of valence electrons increases by one with each element. This is because the atomic number increases, resulting in a higher number of electrons in the outermost shell (valence shell).

As you move from left to right across the periodic table, the number of valence electrons increases by one at a time. This increase results in a higher effective nuclear charge, which leads to increased attraction between the nucleus and the electrons.

Why is silicone a widely preferred semiconductor?
because its valence electrons are free and it is used to the free moving of electrons..so they are used as semiconductors
When moving down a group ( family) in the periodic table the number of valence electrons?
When moving down a group, the number of valence electrons do not change. This similarity yields the elements in the same groups to have same chemical properties. For example, elements in group 17 obtain one electron to stabilize as -1 ion.In a group, all the elements have a same number of valence electrons. So their chemical properties are equal. But the physical properties vary.Valence electrons are the electrons in outermost shell.The valence electrons remain same in a group. For example-Group-1 elements have 1 valence electron.
