The valence electrons found in metallic bonds give metals which characteristics
Free- Roaming electrons, and conductivity
How do you know that a bond between magnesium and chlorine will be ionic
The difference in electronegativity between the two atoms is
above 1.7, Magnesium is a metal, and chlorine is a nonmetal.
Atoms with a low ionization energy hold tight to their outer valence electrons
No; the phrase given characterizes high rather than low
ionization.
Polyatomic ions always carry a positive charge
When hydrogen is attached to the more highly electronegative oxygen atom in a water molecule
the oxygen atom becomes partially negative the hydrogen atom
becomes partially positive
Atoms with a low electronegativity like calcium might bond with
an atom with a high electronegativity, like fluorine
Elements that typically attract electrons are what
When atoms in a covalent bond have a rather high difference in the electronegativities the bond is set to be
When atoms in a covalent bond share electrons equally the bond is said to be .
The change that takes place when two or more substances what to form new substances is called a chemical reaction
If a chlorine atom were to attract an electron from sodium the chlorine atom would become charged.
Why are the valence electrons found in metallic bonds different from other bonds because of what
Metallic bonds have delocalized electrons.
Atoms like sodium and lithium often lose electrons, which makes them
