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>
The answer is: Electrons are shared in each pi bond. If the pi bonds flip back and forth between the adjacent p-orbitals on the two sides of an atom, the shared electrons in the p-orbitals can become delocalized.
Hope this help
The valence electron ring is full. The ring has 8 electrons already.
Answer:
: conjugate acid of 
: conjugate base of 
: conjugate base of
: conjugate acid of
Explanation:
According to the Bronsted-Lowry conjugate acid-base theory, an acid is defined as a substance which looses donates protons and thus forming conjugate base and a base is defined as a substance which accepts protons and thus forming conjugate acid.
Here in forward reaction is accepting a proton, thus it is considered as a base and after accepting a proton, it forms which is a conjugate acid.
And is losing a proton, thus it is considered as an acid and after loosing a proton, it forms which is a conjugate base.
Similarly in the backward reaction, is loosing a proton, thus it is considered as a acid and after loosing a proton, it forms which is a conjugate base.
And is accepting a proton, thus it is considered as a base and after accepting a proton, it forms 
which is a conjugate acid.
Answer:
this isn't correct answer but the equation is correct by using this methid you can got your answer .
Explanation:
Given - Mass number of atom = 23
Atomic number of atom = 11
As, no. of electrons in an atom is equal to an atomic number of the element.
So, number of electrons = 11
Secondly , number of protons are equal to number of electrons.
so, number of protons = 11
And number of neutrons = mass number - atomic number = 23−11 = 12
so, number of neutrons = 12
So , the atom contains 11 protons, 11 electrons, 12 neutrons.
