Smallest to largest atomic radius PotassiumMagnesiumCalciumRubidium?
mg, ca,k ,rb magnesium, calcium, potassium, rubidium as you do down a group atomic radius increases as you go across a period atomic radius decreases
What species has the smallest atomic radius between Kor Mg orRb or Ca?
Mg
Which element between calcium potassium scandium and titanium has the smallest atomic radius?
Atomic radius (in 10^-12 m): K : 231 Ca: 197 Sc: 160 Ti: 146 (smallest)
What has a larger atomic radius Cl ion or Ca ion?
Calcium has the larger atomic radius than chlorine. Calcium has four energy levels, whereas chlorine has three energy levels. The higher the energy level, the farther it is from the atomic nucleus.
Which has the larger radius Ca or Kr?
Ca As you go down a period, the atomic radius decreases

Which element is the largest K Rb Na Li?
Rb is the largest, Li the smallest in the row above. Group 1 of the periodic table: Fr > Cs > Rb > K > Na > Li > H
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 has the larger radius Ca or Kr?
Ca As you go down a period, the atomic radius decreases
What elements have a smaller atomic radius than strontium?
Ca, Mg, Be, Fr, Cs, Rb, K, Na, Li, H
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.
What is the symbol for calcium?
Ca(NO3)2Taken from: http://www.fordhamprep.org/gcurran/sho/sho/lessons/lesson53.htm
How many grams are there in .761 moles of Ca?
For this you need the atomic mass of Ca. Take the number of moles and multiply it by the atomic mass. Divide by one mole for units to cancel. Ca= 40.1 grams.761 moles Ca × (40.1 grams) = 30.5 grams Ca
What is the symbol for Calcium in the Periodic Table?
The atomic symbol for an isotope of calcium will be the regular symbol for calcium, Ca. The number of protons will differ from standard calcium. This is written below the mass number Ca.
