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

false

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

Halogens.

When atoms in a covalent bond have a rather high difference in the electronegativities the bond is set to be

A polar covalent bond.

When atoms in a covalent bond share electrons equally the bond is said to be .

it is a sigma bond.

The change that takes place when two or more substances what to form new substances is called a chemical reaction

(Apex) interact

If a chlorine atom were to attract an electron from sodium the chlorine atom would become charged.

positively

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

cations
