What property generally decreases across the periodic table from sodium to chlorine?

Which of the following properties generally decreases across the periodic table from sodium to chlorine? The effective nuclear charge experienced by the outermost electron of Na is different than the effective nuclear charge experienced by the outermost electron of Ne.

Why is there a decrease in atomic radius from Na to Cl?

Across the periodic table from Na to Cl, the number of electrons in the s- and p- orbitals of the valence shell increases, as does the number of protons in the nucleus. This results in a greater attraction for the electrons, drawing them closer to the nucleus, making the atom smaller.

Why is F ion smaller than onion?

Hence, the atomic radius of a neutral fluorine atom is smaller than a neutral oxygen atom. Moreover, atomic number of fluorine is 9 and it has higher nuclear charge due to which it will cause more attraction of electrons. As a result, size of a fluorine ion will be smaller.

Which of the following best explains why the f1 ion is smaller than the O2 ion?

F-ion is smaller when compared with O2-ion because of the larger nucleus charge of the F-ion. This is because of the presence of more protons in F-ion that pulls the electrons on the shell’s outside, thus making it smaller.

Is O2 or Na+ larger?

In other words, Na+ has bigger effective nuclear charge than O2− , which translates to a bigger net positive charge felt by the outermost electrons. This will compress the energy levels a bit and make the ionic radius smaller for the sodium cation. Therefore, the oxide anion will have the larger atomic radius.

Why the ionic radius of N3 is larger than that of O2?

(a) Potassium has a lower first-ionization energy than lithium. (b) The ionic radius of N3- is larger than that of O2-. Even though both ions are isoelectronic, there is a greater nuclear positive charge in the oxide ion causing its electrons to be more tightly pulled toward the nucleus.

Is P3 smaller than As3?

P3− is smaller than As3−.

Which ion is larger N3 or P3?

Answer: P3 – is larger radius than N3-.

Which ion is larger K+ or Ca2+?

(d) K+ is larger than Ca2+ Isoelectronic; Ca2+ has more protons to pull e- inward.

What is the radius of P3?

Trends in ionic radius across a period

	Na+	P3-
no of protons	11	15
electronic structure of ion	2,8	2,8,8
ionic radius (nm)	0.102	(0.212)

What is the atomic radius of Li+?

Metallic, Covalent and Ionic Radii(r)*

Atom/Ion	r(pm)
Li+	76
Lu	172
Lu3+	86
Mg	160

Is K+ bigger than F?

The atomic radius of potassium is larger than the ionic radius because potassium looses the outer electron and energy level thereby reducing in size while fluoride ion gains electrons and maintain the same energy levels hence become larger.
