Valence electrons in a metallic bond are delocalized and can move freely within the metal atoms. This gives metals their malleability and luster.

Why Mg is harder than Na?
Mg. Mg has 2 valence electrons while Na only has 1 valence electron. Mg+2 also has a smaller ionic radius than Na+. Metallic bonds are stronger when metals have more valence electrons and smaller ion size. The metallic bond will be stronger for Mg. Thus, Mg will have the higher melting point.
What is a bond formed by the attraction between positively charged metal ions and the electrons around them?
Metallic Bond .
Explain what does the strength of a metallic bond depends upon?
Number of valence electrons-The greater the number of freely mobile valence electrons, the higher the charge of positive metal ion, the stronger the metallic bond. Size of metal atom or ion-The smaller the size of the metal ion, the closer the nuclei of metal cations are to the delocalized mobile electrons, the stronger the forces of attraction between the electrons and nuclei, the stronger the metallic bonds.
What happens to the outermost levels of metal atoms in a metallic bond?
They OVERLAP
Is lithium nitride ionic or covalent bond?
ionic lithium loses its one valence electron, becoming a positive ion iodine gains a valence electron (giving it all eight valence electrons), becoming a negative ion
What happens to the valence electrons of atoms in metallic bond?
Metals have metal bonds. valence electron make bonds with metal ions.
What type of bond is formed when gold bonds with itself?
Metallic bond, metallic positive grains surrounded by the electron cloud
What is the electron behavior for metallic bond?
electron sea
What determins the strength of metallic bond?
The number of valence electrons determines the strength of the metallic bond. The more the stronger the bond will be.
What is responsible for an ionic bond?
An ionic bond is a bond that is resulted between two atoms because of an electron transfer. This happens by thephenomenaatoms have to be attracted to other atoms who will complete their valence electron shell.
What type of bonding is present in metals?
Metals have what is called a metallic bond, in which all the constituent atoms share their valence electrons in the form of an electron cloud.
The bond between opositive charge ions is?
the bond is metallic bond where it joins metals in a crystal lattice, the atoms occupy lattice positions as positive ions, and valence electrons are shared between all the ions in an 'electron gas'.
When electrons are transfered between the atoms of metallic and nonmetallic elements what kind of bonds are formed?
When a metallic atom and a nonmetallic atom have an electron transfer to form an ion, this is known as an ionic compound. For example, salt (NaCl) an electron transfer occurs. The Na, which has 1 electron on its valence shell ( outer shell) and the Cl, which has 7 electrons on its valence shell. The Na transfers its one electron to the Cl. This therefore results in the Cl having a full valence shell; at this point Cl is negative and Na is positive. We can then conclude the NaCl is an ionic compound.
What is valence orbital?
A valence electron, also known as valence orbital, is basically composed of electron and atoms that can make a chemical bond. Valence electrons identify other elementÕs chemical properties to determine if the element may bond with other elements.
Lithium has one valence electron Bromine has seven valence electrons How might they form a chemical bond?
lithium donates an electron to bromine
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
How does the number of valence electrons affect an element?
The number of valence electrons affect the type of bond formed by an atom with other atoms as it determines the number and type of atoms it needs to bond with. An atom with one valence electron, for example, will bond with one atom that needs one electron.
