Compare the three types of bonds based on what happens to the valence electrons of the atoms?

In covalent bonding the valence electrons are shared across the orbitals, in ionic bonding the electrons move from one atom's orbital to another. In metallic bonding the valence electrons are delocalised and free to move within the lattice.

∙ 13y agoThe three types of chemical bonds are ionic bonds, covalent bonds, and metallic bonds.
In an ionic bond, one or more atoms (cations) give away all of its electrons to another atom or atoms (anions). This type of bond only occurs between a nonmetal(s) and a metal(s). For example, in NaCl (sodium chloride or salt) the sodium gives its 1 valence electron away to the chlorine atom, which has 7 atoms. They thus complete the octet, or 8 valence electrons, around the anion. However, an ionic bond only works if you can complete the octet, and you might need several cations and/or anions to do this.
In a covalent bond, the valence electrons are shared between each other. This type of bond only occurs between 2 or more nonmetals. For example, in H2O (water), the oxygen bond pairs are shared between the hydrogen bond pairs in order to form the compound.
In a metallic bond, the valence electrons are also shared amognst each other, similar to a covalent bond. This type of bond only occurs between 2 or more metals. However, not all metallic bonds behave in this way. Sometimes, a metallic bond can act like an ionic bond and give all of its electrons away to one element. And in certain cases, the whole compound can become neutral.

Covalent bond: electrons are shared betwee two atoms.
Metallic bond: electrons are delocalized.

How many valence electrons do stable atoms have?
A stable atom has 8 electrons in its outer most valence shell. A simple way to remember this is that all atoms want to be like the noble gases which all have 8 electrons (except helium but the reason is complicated and not necessary here)
Which atoms are most reactive?
The most reactive elements have either 1 valence electron or 7 valence electrons
What term is used to describe the sharing of valence electrons between two or more atoms?
When atoms share electrons as opposed to transferring them, the atoms are covalently bonded.
What is the importance of valence electrons in the organization of the periodic table?
The importance of valence electrons is that atoms in the same group ("groups" in the periodic table are the vertical columns- for example, nickel and platinum are in the tenth column; therefore, in the same group). Atoms of elements in the same group have the same number of valence electrons, so they have similar properties. Hope that helped with your homework! ;D
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.
When metals react with other elements what happens to the valence electrons of the the atoms?
== == When metals react with other elements, the atoms of the metals give up their valence electrons.

What happens two electrons when atoms share covalent bond?
They are shared by the valence shells of the atoms involved in the bond.
