Which is larger F or F 1?
F-1 is bigger because it has one more electron than F, therefor making it bigger..
What has the largest atomic radius?
CesiumThe element which has the largest atomic radius is Cesium. Atomic Radius is defined as the distance between the center of the nucleus and the outermost shell of an atom.
Is mg2+ bigger than F?
BONUS. (8 points) Why is the Mg2+ ion smaller than F–, even though they are isoelectronic? Because while having the same number of electrons, Mg2+ has 12 protons and F– has only 9. Therefore, the electron attraction to the nucleus is greater in Mg2+ making it smaller.
Which is larger Li+ or Na+?
(c) Using principles of atomic structure, explain why the Na+ ion is larger than the Li+ ion. The valence electrons in the Na+ ion are in a higher principal energy level than the valence electrons in the Li+ ion. Electrons in higher principal energy levels are, on average, farther from the nucleus.
Which ion is larger o2 or s2?
S2 is larger than O2 because S2 has more electrons than O2. … S2 is larger than K+ because the decrease in electron repulsions that accompany addition of an electron causes the electron cloud to expand.
Is O bigger than F?
From top to bottom of the periodic table ions will increase in radii. However, now left to right the radius is more of a function of the number of electrons. … Similarly, O2- will be larger than F- as both have 10 electrons but Z=8 for oxygen and Z=9 for fluorine.
Which is larger K+ or ca2+?
K has four shells, S only has three. (b) List the ions in order of increasing size. ION RADIUS K+ < Cl- < S2- In this isoelectronic series, more protons means smaller radius. ... (d) K+ is larger than Ca2+ Isoelectronic; Ca2+ has more protons to pull e- inward.
Which is smaller F or F?
We know that F and F- are both smaller than the rest because they have less shells. Now between F and F-: F- has one more electron, which causes the radius to be bigger.
Is K+ smaller than ca2+?
(d) K+ is larger than Ca2+ Isoelectronic; Ca2+ has more protons to pull e- inward.
Which is larger Cl or Ar?
Cl- has the same number of electrons as Ar, but it has less protons, so less of a positive charge pulling those electrons to the nucleus, so will has a larger radius.
Which is larger K+ or Cl?
In other words, K+ has bigger effective nuclear charge than Cl− , 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 potassium cation. Therefore, the chloride anion will have the larger atomic radius.
Which of the following is the smallest cation?
Boron is the smallest ion because it looses 3 electrons and gains a duplet state. Lithium, berilium also gain duplet state but have lesser number protons in their nucleus. Boron has the maximum number of protons among them so they have the maximum nuclear pull, so boron is the smallest Cation.
Is al3+ smaller than mg2+?
As they have equal number of electrons the electrons are not involving in determination of atomic radius. Hence atomic radius is totally depended on effective nuclear charge. Therefore radius of Al3+ is less than Mg2+.
Which is smaller in size O or o2?
Atomic radius of an atom is defined as the total distance from the nucleus to the outermost shell of the atom. Oxygen is an element with atomic number of 8 and thus has 8 electrons and 8 protons. … The attraction of 9 electrons is more by 8 protons and thus is shorter in size.
