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 the size of an ion after it has gained or lost electrons, leading to a change in the electron configuration and thus its size. Atomic radius refers to the size of an atom, typically measured as the distance from the nucleus to the outermost electron shell. Ionic radius is affected by the change in electron configuration, while atomic radius is more related to the position of the outer electrons in the neutral atom.


Why are the ionic radii of positive ions smaller than their corresponding atomic radii?

Positive ions have lost electrons, resulting in fewer electron-electron repulsions within the electron cloud, causing it to shrink. This leads to a smaller ionic radius compared to the corresponding neutral atom.


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).


How is an ionic radius and an atomic radius related?

Ionasion energy decreases as the shielding effect increases , due to the fact that more electrons are available and less nuclear attraction takes place. Therefore lower ionasion energy will be required.


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 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.


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 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.
