Question

100 points! Formation of an Ion

Answer 1

Given the chemical formula Al2O3  and every oxygen ion (combined with an aluminum ion) has a charge of -2, the total negative charge is -2x3 = -6.

As Al2O3 is neutral, the total positive charge must be 6.  The charge of each aluminum ion is 6/2 = 3.

An uncharged aluminum atom must lose 3 electrons so that it will bond with oxygen.

Answer 2

$\huge\bold {Answer}$

Aluminum ions have a charge of +3. This means that the atoms have three more protons than electrons. In order to add electrons to aluminum ions, the purification process therefore requires a large amount of electricity.

Uncharged Aluminum atom must need to lose it's electrons,in order to form the bond with oxygen which has vacant orbitals

ion
atom that has a positive or negative charge because it lost or gained one or more electrons

chemical bond
the attractive force that holds atoms or ions together

ionic bond
a chemical bond in which one atom loses an electron and the other atom gains electrons to form ions

chemical formula
a combination of chemical symbols and numbers to represent a substance

covalent bond
bond formed by the sharing of electrons between atoms
