Which of the following has the largest radius K Na Na+ K?
K+ has a larger atomic radius than Na+. The Periodic Table is accompanied by many trends. One such trend involves the atomic radius for these elements. As you go down the periodic table, the atomic radius increases which is why K+ has a larger radius… it’s below Na+.
Which has a larger radius Na or K?
As an example, potassium (K) has a larger average atomic radius (220 pm)than sodium (Na) does (180 pm). The potassium atom has an extra electron shell compared to the sodium atom, which means its valence electrons are further from the nucleus, giving potassium a larger atomic radius.
Which is larger k or k?
The cation of K+ is formed when K loses this outermost single electron to attain “electronic configuration” of: The K+ ion has its outermost electrons on the third energy level now and is size is smaller than that of K ion. Hence, K is larger than K+.
Which one of the following has the largest radius?
Thus O2− has a minimum z-effective thus largest radius.
Why is K bigger than Br?
Since potassium is located at the start of period 3, and bromine at the end of the same period, potassium will have a larger atomic radius than bromine, and thus the largest atomic radius of the four given atoms.
Which ion has largest radius?
1 Answer. Ernest Z. K+ has the largest radius.
Which is bigger Na or Na+?
The total number of electrons is 10 in case of Na+ and 11 in case of Na, while the number of proton is same i.e. 11 in both case.
Is Br or Br bigger?
Br – will have the largest atomic size because Br- has one extra electron in its valence shell which due to its unbalanced negative charge will be repelled and hence the atomic radius of Br- will increase.
Is mg bigger than na?
(i) The sodium ion (Na+) is larger than the magnesium ion (Mg2+) due to two effects.
Is potassium K or K +?
Potassium is a chemical element with symbol K and atomic number 19. Classified as an alkali metal, Potassium is a solid at room temperature.
…

What is the highest energy level for K?
Potassium, K , is located in period 4, group 1 of the periodic table, which means that it has one electron on its highest energy level. The size of a potassium atom is determined by how far that solitary electron that resides on the highest energy level, i.e on the fourth energy level, is from the nucleus.
What is the atomic radius of K+?
280 pm
Which has the largest radius Co3+ Mn3+ fe3+ Cr3+?
Fe 3+ has highest radii because by going left to right in the periodic table , the size get decreased so .. Fe 3+ >Co3+ >Cr3+ >Mn3+ .
How is atomic radius measured?
The radius of an atom can only be found by measuring the distance between the nuclei of two touching atoms, and then halving that distance. … The type of atomic radius being measured here is called the metallic radius or the covalent radius depending on the bonding.
Which of the following has the largest radius answers com?
Jupiter is the largest planet and therefore has the largest radius.
