Answer:
A positive ion has fewer electrons, and importantly, fewer electron shells (since atoms usually lose electrons until they get down to an empty outer shell.) This makes it smaller than a neutral atom of that element.
A negative ion has more electrons, and importantly, greater electron-electron repulsion in its outer shell. This makes it larger than a neutral atom of that element.

Answer:
CH2
Explanation:
We are given that a compound is 14.40% hydrogen and 85.60% carbon.
Let the mass of the substance be 100g.
Mass of the hydrogen: 14.40% of 100 = 14.40 g
Mass of the carbon: 85.60% of 100 = 85.60 g
Now, let's find the moles of hydrogen:
![14.40 g*\frac{1 mole}{1gH} = 14.40 mole](https://tex.z-dn.net/?f=14.40%20g%2A%5Cfrac%7B1%20mole%7D%7B1gH%7D%20%3D%2014.40%20mole)
Moles of carbon:
![85.60g*\frac{1 mol}{12gC} = 7.13mol](https://tex.z-dn.net/?f=85.60g%2A%5Cfrac%7B1%20mol%7D%7B12gC%7D%20%3D%207.13mol)
Let's put these in a ratio and simplify:
7.13 mole C: 14.40 mole H
1 mole C: 2 mole H
Therefore, the empirical formula of this compound is CH2.
