They are either transferred or shared. In ionic bonds, electrons are transferred, and shared in covalent bonds.
What else can I help you with?
Which type of substances have chemical bonds that are not directional and valence electrons that move freely between the atoms?
Metals.
What happens to a valence electron in a metallic bond?
In a metallic bond, valence electrons are delocalized and are free to move throughout the entire structure of the metal. This leads to properties such as high electrical and thermal conductivity. The mobility of these electrons allows metals to conduct electricity and heat efficiently.
What is happening to the elements electronic structures in group 1?
In Group 1 of the periodic table, the elements have one valence electron. As you move down the group, the size of the atoms increases due to the addition of more energy levels. As a result, the outermost electron becomes further away from the positively charged nucleus and more shielded by inner electrons. Thus, the electronic structure remains similar, with one valence electron, but the atoms become larger in size.
How many valence electrons are in Alika metals?
Alkali metals, which are found in Group 1 of the periodic table, have one valence electron. This single valence electron is responsible for their characteristic reactivity and the formation of positive ions. As you move down the group, the number of electron shells increases, but the number of valence electrons remains the same at one.
How many electrons do group 1A elements have in their valence shell?
Group 1A elements, also known as alkali metals, have one electron in their valence shell. This single valence electron is responsible for their high reactivity and tendency to lose that electron to form positive ions. As you move down the group, the number of electron shells increases, but the number of valence electrons remains the same at one.
What are two ways in which valence electrons move between the atoms?
Protans & nutrons
Which type of substances have chemical bonds that are not directional and valence electrons that move freely between the atoms?
Metals.
What is the periodic trends in ionization energy?
The ionization energy increases because the energy required to remove a valence electron will increase. The atoms want to keep their valence electrons because as you move more towards the right of the Periodic Table towards the noble gases. To write an abbreviation for electron configuration, it requires a noble gas and the valence electron configuration.
What is the period trend in first ionized energies?
The ionization energy increases because the energy required to remove a valence electron will increase. The atoms want to keep their valence electrons because as you move more towards the right of the Periodic Table towards the noble gases. To write an abbreviation for electron configuration, it requires a noble gas and the valence electron configuration.
What happens in a molecule when a covalent bond is formed?
In a covalent bond, the electrons are shared. For ex. when 2 hydrogens and one oxygen are paired up, they form a covalent bond. hydrogen has 1 valence electron and oxygen has 6. so they bond together so they all have their valence orbit filled

Why are the valance electrons of metallic bonds different from other bonds?
In a metal the valence electrons delocalize into the conduction band, becoming an "electron gas" that fills the metal's bulk volume.In covalent bonds the valence electrons are shared between local pairs of atoms.In ionic bonds the valence electrons leave the "metal" and move to the "nonmetal" creating a pair of separate oppositely charged ions.In resonance bonds the valence electrons oscillate between being shared between two nearby local pairs of atoms.etc.To summarize in metals the valence electrons become delocalized, in other bonds the valence electrons stay local.
What happens to the valence electrons of atoms in metallic bond?
In metallic bonding, valence electrons are delocalized and free to move among the atoms. This creates a "sea of electrons" that holds the metal atoms together in a lattice structure. The sharing of electrons in this way gives metals their characteristic properties, such as conductivity and malleability.
Why can metals conduct electricity but remain unchanged?
Only the free valence electrons forming the electron "gas" move and as many move in as move out. Only metals form this electron "gas".
