There are 2 significant figures in this number. A significant figure is any number that isn’t 0. Hope this helps.
The correct is this because they said
<span>The effective nuclear charge of an atom = total electrons - inner electrons
For O, ENC = 8 - 2 = 6
For Li, ENC = 3 - 2 = 1
For C, ENC = 6 - 2 = 4
The electrons in O experience the greatest effective nuclear charge and that is why O is smaller than C (which is smaller than Li).</span>
Answer:
Yes it will
An example is ice, when it melts the volume goes up which means it occupies much more space
The answer would be Sedimentary
