Valence electrons are the electrons present in the outermost shell of an atom. You can easily determine the number of valence electrons an atom can have by looking at its Group in the periodic table. ... Valence electrons are responsible for the reactivity of an element.
ions
octer rule
you lerned in chapter 6 that noble gases such as neon and argon are unractive in chemical reaction the explanation of the octed rule in forming compounds atoms tend to achieve the electron configuration in noble gas
mettallic bonds and mettallic properties
the valence electrons of metal atoms can be modeled of one parts the metal metalic bonds
When there is the strong electrostatic force of attraction between a cation and an anion (two oppositely charged ions) of elements is called ionic bond and is formed between a metal and a non-metal. ... Metallic bonds are malleable and ductile, while covalent bonds and ionic bonds non-malleable and non-ductile
compounds composed of cations and anions are called ionic compounds are electrelly neutral the total positive
