What is the approximate geometry around each oxygen atom
AnnyKZ [126]

Answer:

correct option: A. tetrahedral

Explanation:

when we talk about hydrogen bonding in water due to oxygen then need to check the number of lone pair available for hydrogen bonding because hydrogen bond form between lone pair of oxygen and hydrogen of other water molecule so there are two lone pair which forms hydrogen bond and there are also two other covalent bond with hydrogen of same molecule so total number is 4 it means they will form a tetrahedral geometry

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>
