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.

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?
Valence electrons increase in number on moving from left to right on the periodic table. another question might be
Do freely moving valence electrons account for electrical conductivity in metals?
yes they conduct electricity
What term is used for the electrons in the outermost shell?
there called valence electrons
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?
When moving down a column in the periodic table, except for the first period of column 18, the number of valence electrons remains unchanged.
Is gold iii sulfide ionic or covalent?
Gold is a metal and so its bonding is via 'Sea of Electrons'. This is not perfectly ionic nor perfectly covalent. Rather, the valence electrons are delocalised and moving within atomic orbitals of all immediate neighbouring atoms...
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).

How do you identify the various types of bonds?
There are three types of chemical bonds. Ionic, covalent and metallic. Ionic is where a metal and a non metal combine and transfer electrons Covalent is where two non-metals combine and share their outer shell electrons Metallic is where you have a metal such as iron or aluminium. Inside the medal cation is a sea of delocalised electrons which create an electrostatic attraction between the positively charged cations (metal e.g iron) and the negatively charged delocalised (free moving) electrons. This is what makes some metals malleable because the bond is non-directional, meaning the cation can slide over each cation due to the constant attraction between the delocalised 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.
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.
What happends to the valence electrons is they are moved from left to right in the periodic table?

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
