false. they are smaller because they have lost one or more electrons.

False. As a neutral atom will lose one or more electrons to become positive the atom will become smaller. Sodium for example will lose its outer shell (of one electron) when it becomes an ion and an hydrogen ion is just a single proton (and you can't get much smaller than that!)

False - the neutral atom has a radius of x.
The positive ion will have the radius of x minus the radius of the orbitals occupied by the electron(s) removed to create the ion.
It's a trick question. They tell you it's a + ion, to make you think it will be bigger - but remember that to be a positive ion it has to missing at least one electron, making it smaller.

false... positive ions is made by abstracting electrons in the neutral atom. doing so makes the electron cloud smaller thus the positive ions of an atom is smaller than the neutral atom..
best answer?

False.
Positive ions mean they have LOST electrons because they have more p+ than e- so they are +.
Losing electrons causes the radius to shrink so it therefore is always smaller.

That's false. They're always smaller.
