Which has smaller size F or Na+?

Na+ has smaller size than F- because both Na+ and F- have equal number of electrons i.e.10 . After losing an electron Na will have less electron cloud and more effective nuclear charge whereas F after gaining an electron will have less effective nuclear charge than the parent atom so the size increases .

Which one has larger size Na or F?

Is fluorine bigger than na?

Sodium atoms are larger than fluorine atoms, but sodium ions are smaller than fluorine ions.

Is sodium ion bigger than fluorine ion?

Why sodium ion is smaller than sodium atom while fluoride ion is bigger than fluorine atom.

Which is bigger Na or Na+?

Yes Na+ is smaller than Na because Na+ is formed when an electron is lost from the Na atom,Thus the effective nuclear charge increases bcz the number of protons exceeds the number of electrons . This results in bringing the valence shell a little closer to the nucleus because of a very strong nuclear pull.

Which of the following atoms has the smallest size?

Atomic radii vary in a predictable way across the periodic table. As can be seen in the figures below, the atomic radius increases from top to bottom in a group, and decreases from left to right across a period. Thus, helium is the smallest element, and francium is the largest.

Which is smaller a fluorine atom or a fluorine ion?

Statement I: The fluoride ion has a larger radius than the fluorine atom. Statement II: The fluoride ion has 8 electrons and 9 protons.

Why is sodium ion smaller in size than sodium atom?

The primary reason sodium ions are smaller than sodium atoms is that the ion has only two shells of electrons (the atom has three). Some resources suggest the ion gets smaller since there are less electrons being pulled by the nucleus. Comments?

Is the O2 ion smaller than the F ion?

Fluorine is smaller than oxygen because as we move across a period the size of the elements decreases.

Why is na+ smaller than F-?

Since sodium has a higher atomic number (number of protons), the nuclear charge will be stronger. For this reason, Na+ is smaller than F-. F atomic number is 9 having 9-electrons & 9-protons. After gaining electron, it becomes F-having 10-electrons and 9-protons.

Why is the size of Na+ ion smaller than that of NE?

As no. of protons present in sodium ion is 11 , greater the nuclear charge greater will be the attraction of nucleus towards valence shell electrons and size decreases. Though both of them are isoelectronics, due to high nuclear charge of Na+ ion it is smaller than that of Ne.

Which ion has the smallest size in atomic table?

Largest in size out of Na+ Ne and F- is. Explain your answer. Largest in size out of Na+ Ne and F- is. Explain your answer. We will notify on your mail & mobile when someone answers this question. F- is the most electronegative ion. Thus, it has the smallest size possible in atomic table. Coming to Ne, it has no charge on it.

Why Nana+ has smaller size than F-?

Na+ has smaller size than F- because both Na+ and F- have equal number of electrons i.e.10 . After losing an electron Na will have less electron cloud and more effective nuclear charge whereas F after gaining an electron will have less effective nuclear charge than the parent atom so the size increases .I hope this explains about this question .
