What else can I help you with?
Which has the larger radius Ca or Kr?
Ca has a larger atomic radius compared to Kr. This is because atomic radius tends to increase as you move down a group on the periodic table, so Ca, being in Group 2, has a larger atomic radius than Kr, which is in Group 18.
Which ion has the smallest ionic radius Mg2 plus or Ca2 plus?
Mg2+ has the smaller ionic radius compared to Ca2+ because as you move down a group in the periodic table, the ionic radius increases due to the addition of electron shells. Mg and Ca are in the same group, but Ca has more electron shells than Mg, resulting in a larger ionic radius for Ca2+.
What species has the smallest atomic radius between Kor Mg orRb or Ca?
The species with the smallest atomic radius among K, Mg, Rb, and Ca is Rb (Rubidium). This is because atomic radius tends to decrease across a period from left to right in the periodic table, and Rb is located towards the right side of this group of elements.
Is The Ca plus 2 ion larger than the Ca atom?
Mg2+ is larger Now, as for the logic behind this problem...The first thing to do is recognize that Ca2+ (Calcium) has lost 2 of its electrons, therefore its valence electron structure is the same as Ar's (Argon). Ar is in the same row as Mg. The trend for atomic radii is increasing to the left and down. Atomic radius increases to the left because the atoms to the right have more particles in the nucleus than their counterparts to the left; thus, the electrons are drawn closer to the nucleus, and the atomic radius is diminished.
Smallest to largest atomic radius PotassiumMagnesiumCalciumRubidium?
Rubidium has the largest atomic radius, followed by potassium, calcium, and then magnesium. This trend is due to an increase in the number of electron shells and shielding effects as you move down the periodic table from potassium to rubidium.
Which has the larger radius Ca or Kr?
Ca has a larger atomic radius compared to Kr. This is because atomic radius tends to increase as you move down a group on the periodic table, so Ca, being in Group 2, has a larger atomic radius than Kr, which is in Group 18.
Which has the greatest atomic radius K or Ca?
Both atoms have the same van der Waal's radius (2.00) Radii that are not available in either of these publications have RvdW 2.00 A. However, Caesium has a greater covalent radius (1.67) as compared to that of Radon (1.50) See the link for more info.
Which ion has the smallest ionic radius Mg2 plus or Ca2 plus?
Mg2+ has the smaller ionic radius compared to Ca2+ because as you move down a group in the periodic table, the ionic radius increases due to the addition of electron shells. Mg and Ca are in the same group, but Ca has more electron shells than Mg, resulting in a larger ionic radius for Ca2+.

Is ca plus 2 or mg plus 2 larger?
The Ca2+ ion is larger than the Mg2+ ion. The ionic radii are: 86pm for the Mg2+ and 114pm for the Ca2+. Besides the fact that the Ca2+ has more electrons this can be explained by the principle of electron shielding. Electron shielding is when lower level electrons block the EFC(effective nuclear charge) from effecting the valence electrons of an ion. Ca2+has more electrons than Mg2+ so more electron shielding occurs.
Smallest to largest atomic radius PotassiumMagnesiumCalciumRubidium?
Rubidium has the largest atomic radius, followed by potassium, calcium, and then magnesium. This trend is due to an increase in the number of electron shells and shielding effects as you move down the periodic table from potassium to rubidium.
Which is bigger Ca or Br?
Calcium has atomic number 20 and bromine is 35, so bromine has a bigger nucleus if that is what you mean
Largest atomic radius out of Ca Na Fe Al and k?
K (potassium) would have the largest atomic radius out of the elements given because it is located in the lower left corner of the periodic table. As you move down a group in the periodic table, the atomic radius increases due to the addition of more electron shells.
What elements have a smaller atomic radius than strontium?
Ca, Mg, Be, Fr, Cs, Rb, K, Na, Li, H
What is the symbol for the ion Ca?
The symbol for the calcium ion is Ca^2+.
Which of these is an ion with a plus 2 plus charge O Al Na Ca?
the atomic no of calcium is 20 so to reach the nearest noble gas electronic configuration it loses 2 electrons and forms + 2 ion.
