It's A
a. the electron configuration of a noble gas.
Explanation:
<em>First</em><em> </em><em>two</em><em> </em><em>pictures</em><em> </em><em>go</em><em> </em><em>together</em>
From top to bottom, <em>ionisation energy</em> <em>decreases</em><em> </em>[electron shielding], while from left to right, ionisation energy <em>increases</em><em> </em>[valence shell stability]. Noble gases always always possess such high energy of ionisation because they are stable, with Helium having the highest ionisation of all elements.
From top to bottom, <em>electron affinity</em> <em>decreases</em> [decrease in atomic radius], while from left to right, electron affinity <em>increases</em><em> </em>[increase in atomic radius].
There are many more trends, but I have ran out of space, so I will put this in the comments.
I am joyous to assist you anytime.
The correct answer among the choices given is the third option. When the kinetic energy of particles on a solid state increases, the particles <span>vibrate fast enough to overcome the forces of attraction holding them together and become a liquid. This is due to the increase in the energy of motion in each particle.</span>
Answer:
19
Explanation:
count up from 18 and go up until the arrow
Answer:
-2820 kJ
Explanation:
Just got it right on Ap3x :)
Check your question and verify that it says "multiply" and not "reverse", this is the only page that has the answer for that one.
If you have "reverse" there is another guy who asked the question, is easy to find.
