Which element is the largest K Rb Na Li?
Rb (rubidium) is the largest element among K (potassium), Rb (rubidium), Na (sodium), and Li (lithium). This is because as you move down a group in the periodic table, the atomic size increases due to the addition of more electron shells.
Why is the atomic radius of potassium larger than calcium?
Although they are all group I atoms, Na and K have a nuclear charge representative of s,p,and d electrons. Once you get to Rb the 4f sublevel comes into play along with the significantly increase nuclear charge. As a result, the does not increase as significantly as the Na and K.
What is the area of a 10km radius in square km?
The area of a circle with a radius of 10 km is πr^2, where r is the radius. In this case, the area would be approximately 314.16 square kilometers.
Is K metal or nonmetal?
Potassium (K) is a metal. It is a soft, silvery-white alkali metal with an atomic number of 19.
The correct symbol for the isotope of potassium with 22 neutrons is k 41 19?
The correct symbol for the isotope of potassium with 22 neutrons is K-41. The number after the element symbol represents the atomic mass, which is the sum of protons and neutrons in the nucleus. In this case, potassium has 19 protons and 22 neutrons, resulting in an atomic mass of 41.
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.
Which atom has the larger atomic radius K or Li?
K has a larger atomic radius than Li. This is because atomic radius generally increases down a group in the periodic table, so potassium (K) being below lithium (Li) in Group 1 will have a larger atomic radius.
What is the radius of k?
The atomic radius of potassium is 220pm.
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.
What elements have a smaller atomic radius than strontium?
Ca, Mg, Be, Fr, Cs, Rb, K, Na, Li, H
Which of the following has the largest radius K plus Na plus Na or K?
Potassium has the largest atomic radius.
What is the difference between the atomic radii of sodium (Na) and potassium (K)?
The atomic radius of sodium (Na) is smaller than the atomic radius of potassium (K). Sodium has a smaller atomic radius because it has fewer electron shells compared to potassium.
Does na1 have a larger atomic radius than k1?
K+ has larger radius
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.
How does the presence of core electrons affect the atomic radius of elements?
When there is an anion (negative charge) the radius will be larger because it is more full whereas it will be smaller if it is a positive charge because of less electrons. ex largest to smallest radius (K-,K, K+)
What has the largest radius K or Na?
Postassium, K, has a larger radius than sodium, Na, because it is in the next period on the table but in the same group as sodium.
Which element between calcium potassium scandium and titanium has the smallest atomic radius?
The element with the smallest atomic radius among calcium, potassium, scandium, and titanium is titanium. Atomic radius generally decreases from left to right across a period in the periodic table, and titanium is located towards the right side of the group mentioned.
