Add electron dots and charges as necessary to show the reaction of calcium and oxygen to form an ionic compound.
xxMikexx [17]
The two atoms shown in the equation are CALCIUM and oxygen. 

<span>You start off with a neutral calcium atom with a shell of two electrons, a shell of 8 around that, a shell of 8 around that, and a shell containing 2...with no charge. </span>
<span>20 protons + 20 electrons. </span>

<span>You also have an oxygen atom with a shell of 2, and a shell of 6...with no charge. </span>
<span>8 protons + 8 electrons. </span>

<span>Each ionizes to form a calcium ion with 2 electrons removed (from the outer shell), leaving a +2 charge (20 protons, 18 electrons)... </span>
<span>and an oxygen ion with 2 electrons added (to the outer shell), leaving a -2 charge (8 protons, 10 electrons). </span>

<span>Their electrostatic attraction causes them to come together to form an ionic compound of CaO in a crystal lattice.</span>

Write a statement that shows how the charge of an ion relates to the number of electrons transferred.
DanielleElmas [232]

Answer:

Q = ne

Explanation:

Ler n be the number of electrons transferred and Q be the charge of an ion.

The net charge on the object is then given by :

Q = ne

Where

e is the electronic charge

Hence, the charge of an ion relates to the number of electrons transferred is equal to Q = ne.
