F has one extra electron, which will goes in outer layer making F bigger.
Na has one less electron, which will cause its size to get smaller.

How does ionic radius differ from atomic radius?
Ionic radius is greater than atomic radius in a negative ion and less than it in a positive ion.
Why are the ionic radii of positive ions smaller than their corresponding atomic radii?
Because they have less negative electrons to hold onto & there aren't as many in the outer sublevels, so they can hold them closer to the nucleus causing the radius to shrink.
Why is the radius of a negative ion always greater than the radius of a neutral atom?
A positive ion has less electrons in its shell than a neutral atom. As a result of this, there is less repulsive force between the orbiting electrons (less electrons, less force) and they can come closer to the positively charged nucleus (which is attracting them). You will have an especially large decrease in radius if you remove the last electron from a shell (the electrons are composed into shells, the first one takes 2 electrons, second one 6, the third one 10 and so on).
Compare the size of the radius of a negative ion to its neutral atom?
The size of the Radius of a positve ion is smaller than a neutral atom because the postive ion has lost electrons, which means the outer most shell might be lost as well making the positve ion smaller and the nuetral atom remains the same
What causes an ionic bond form?
A large difference in electronegativity values between the two atoms forming the bond will cause the bond to be ionic. The electrons from the less electronegative atom will be completely donated to the atom with the greater electronegativity. This occurs when a metal and a non metal bond.

What is ionic coumpound?
Compound made of ions, which are atoms of an element with more or less electrons than number of protons, giving them a positive or negative charge.
Is a negative greater or less than a positive number?
A negative number is less than a positive number. Think about it this way: a negative number is less than 0. A positive number is greater than 0. Therefore, a negative number must be less than a positive number.
Is negative 5 greater than positive 0?
Zero isn't positive or negative. All negative numbers are less than zero.There is no such thing as "positive" (or "negative") zero.Also, a negative number is always less than any positive number.
Is a negative and a positive a positive?
In math, a positive is a number greater then zero, and a negative number is less than zero.
How does the size of the atomic radius in a nonmetal compare to size of its ionic radius?
I'm not positive but.... the ionic radius of a metallic atom is slammer than its atomic radius because metallic atoms want to loose electrons. The loss of electrons increases the pull of the nucleus, drawing the electrons closer and thereby making the ionic radius smaller than the atomic radius.
Is negative 56 less than 2?
Yes. A negative number is less than a positive.
What is a positive and What is a negative?
In math, a positive is a number greater then zero, and a negative number is less than zero.
Is negative 8 greater than positive 8?
No, negative 8 is less than positive 8.
